Inside a nuclear power plant, energy is liberated as nuclear reactions proceed inside the core. As this happens, the mass of the nuclei
Decreases.
Stays the same.
Increases.

The tension in the wire just after the collision is 98.1 N.

To solve this problem, we need to use the principle of conservation of momentum and energy.

Before the collision, the momentum of the system is:

p = m1v1 + m2v2

where m1 = 8.00 kg is the mass of the hanging ball, v1 = 0 (since it is at rest), m2 = 2.00 kg is the mass of the moving ball, and v2 = 5.00 m/s is its velocity. Therefore, the initial momentum of the system is:

p_initial = m1v1 + m2v2 = 2.005.00 = 10.00 kgm/s

After the collision, the 2.00 kg ball will stick to the 8.00 kg ball, and they will move together as one body. Since the collision is elastic, the total mechanical energy of the system is conserved. The mechanical energy of the system before the collision is:

E_initial = (1/2)m1v1² + (1/2)m2v2²= 0.52.005.00^2 = 25.00 J

The mechanical energy of the system after the collision is:

E_final = (1/2)MV²

where M = m1 + m2 = 10.00 kg is the mass of the combined system, and V is the velocity of the combined system just after the collision.

Using the principle of conservation of momentum, we know that:

p_initial = p_final

or

m1v1 + m2v2 = (m1 + m2)*V

Substituting the values we know, we get:

8.000 + 2.005.00 = (8.00 + 2.00)*V

V = 1.00 m/s

So, the velocity of the combined system just after the collision is 1.00 m/s.

Now, we can calculate the mechanical energy of the system after the collision:

E_final = (1/2)MV^2 = 0.510.001.00²= 5.00 J

Since the total mechanical energy of the system is conserved, we have:

E_final = E_initial

Therefore, the kinetic energy lost during the collision is:

ΔK = E_initial - E_final = 25.00 - 5.00 = 20.00 J

This kinetic energy is dissipated in the form of internal energy, such as heat, sound, and deformation of the balls.

Finally, we can find the tension in the wire just after the collision by considering the forces acting on the combined system. Since the system is in equilibrium, the tension in the wire must be equal to the weight of the system:

Tension = Weight = M*g

where g = 9.81 m/s² is the acceleration due to gravity.

Substituting the values we know, we get:

Tension = 10.00*9.81 = 98.1 N

The resultant intensity at point P due to two coherent sources of waves X and Y is 4 times the intensity produced by each individual source separately. The resultant intensity at point P due to two coherent sources of waves X and Y can be found using the formula:
I(resultant) = I(X) + I(Y) + 2√(I(X)I(Y))cos(Δφ)

Here, Δφ is the phase difference between the two sources, which is given as zero. Therefore, the cosine term becomes 1 and simplifies the equation to:
I(resultant) = I(X) + I(Y) + 2√(I(X)I(Y))

Given that the intensity at P due to X and Y separately is I, we can substitute this value in the above equation:
I(resultant) = I + I + 2√(I x I)

Simplifying this equation, we get:
I(resultant) = 4I

Therefore, the resultant intensity at point P due to two coherent sources of waves X and Y is 4 times the intensity produced by each individual source separately. The wavelength and distances provided in the question are not used in this calculation.

When the distance between the two slits, d, is increased, the interference pattern will become the wider.

On the other hand, if d is decreased, the interference pattern will become narrower. This is because the phase difference between the waves becomes larger, resulting in a narrower interference pattern.

This is because the distance between the slits affects the phase difference between the waves, which in turn affects the interference pattern. When d is increased, the phase difference between the waves becomes smaller, resulting in a wider interference pattern.


The interference pattern is a phenomenon that occurs when waves interact with each other, producing regions of constructive and destructive interference. In the context of a double-slit experiment, the interference pattern refers to the pattern of light and dark fringes observed on a screen placed behind two closely spaced slits through which light passes.

The distance between the two slits, represented by the variable "d," plays a crucial role in determining the interference pattern. Specifically, the distance between the slits determines the phase difference between the waves that pass through each slit, which in turn affects the pattern of interference.

If the distance "d" between the two slits is increased, the distance traveled by the waves passing through each slit will also increase. This will result in a larger phase difference between the waves, leading to an increase in the spacing between the interference fringes on the screen. In other words, the interference pattern will be spread out over a larger area, resulting in wider and more widely spaced fringes.

Conversely, if the distance "d" between the slits is decreased, the distance traveled by the waves passing through each slit will also decrease.

The trajectory's speed vector, which indicates the meteor's direction of travel, is represented by the vector (6, 5, -2). The asteroid is travelling in the direction of rising x, y, and descending z coordinates since the vector includes components (6, 5, -2).

You'll see that we presumptively started the meteor at (4, 6, 9) at time t=0. In the event that this is not the case, further data would be required to pinpoint the meteor's initial location.

The trajectory of the meteor can be described as:

The repulsive force between two pith balls that are 13.0 cm apart and have equal charges of −38.0 nc is approximately 7.67 x 10^-5 N.

The repulsive force between two pith balls can be calculated using Coulomb's law, which states that the force between two charges is directly proportional to the product of their charges and inversely proportional to the square of the distance between them.

The equation for Coulomb's law is:

F = k * (q1 * q2) / r^2

where F is the force, k is Coulomb's constant (9 x 10^9 N m^2/C^2), q1 and q2 are the charges, and r is the distance between the charges.

Substituting the given values, we get:

F = (9 x 10^9 N m^2/C^2) * (-38.0 x 10^-9 C)^2 / (0.13 m)^2

Simplifying this expression, we get:

F = 7.67 x 10^-5 N (newtons)

a. Therefore, the work required to accelerate an electron from rest to 1.60c is 813 keV. b. Therefore, the final speed of the electron is approximately 0.999999784 times the speed of light (c).

(a) The kinetic energy of a particle with mass m and velocity v is given by:

KE = 1/2 [tex]mv^2[/tex]

An electron has a rest mass of 9.11 x 10^-31 kg. To accelerate an electron from rest to a velocity of 1.60 times the speed of light (c), we can use the relativistic kinetic energy formula:

KE = (γ - 1)[tex]mc^2[/tex]

where γ is the Lorentz factor given by:

γ = 1 / [tex]\sqrt{(1 - (v/c)^2)}[/tex]

At a velocity of 1.60c, the Lorentz factor is:

γ = 1 / [tex]\sqrt{(1 - (1.60c/c)^2)}[/tex] = 2.29

Substituting the values into the relativistic kinetic energy formula, we get:

KE = [tex](2.29 - 1) x (9.11 x 10^{-31} kg) x (3.00 x 10^{8} m/s)^2[/tex]

= [tex]1.30 *10^{-13} J[/tex]

KE = ([tex]1.30 x 10^{-13} J) / (1.60 x 10^{-19} J/eV) = 813 keV[/tex]

(to three significant figures)

(b) If we do that much work on an electron, its final speed can be calculated by equating the work done to the change in kinetic energy:

Work done = ΔKE = KE_final - KE_initial

where the initial kinetic energy is zero, since the electron is initially at rest. Therefore:

Work done = KE_final

Solving for the final velocity using the relativistic kinetic energy formula and the Lorentz factor:

KE_final = (γ - 1)[tex]mc^2[/tex]

KE_final = (813 keV) * [tex](1.60 x 10^{-16} J/eV) = 1.30 x 10^{-7} J[/tex]

γ = 1 + KE_final / (mc^2)

γ = [tex]1 + (1.30 x 10^{-7} J) / ((9.11 x 10^{-31} kg) * (3.00 x 10^8 m/s)^2)[/tex]

The initial kinetic energy of a car traveling at 20 m/s with a mass of 1000 kg is 200,000 J. The change in kinetic energy when the car comes to a stop is -200,000 J, indicating a decrease in kinetic energy.

The initial kinetic energy of the car can be calculated using the formula: KE = 0.5 x m x v^2, where m is the mass of the car and v is its velocity.
KE = 0.5 x 1000 kg x (20 m/s)^2
KE = 200,000 J

When the car comes to a stop, its final kinetic energy is zero. Therefore, the change in kinetic energy can be calculated as:
Change in KE = final KE - initial KE
Change in KE = 0 - 200,000 J
Change in KE = -200,000 J

1.022 × 10⁻⁹ Newtons is the gravitational attraction between the bowling balls are in contact with one another.

To calculate the gravitational attraction between two 6.8-kg bowling balls with a radius of 0.15 m each and in contact with one another, we'll use the formula for gravitational force:
F = G × (m1 ×m2) / r²
where F is the gravitational force, G is the gravitational constant (6.674 × 10⁻¹¹N(m/kg)²), m1 and m2 are the masses of the bowling balls (6.8 kg each), and r is the distance between their centers.
Since the bowling balls are in contact, the distance between their centers is equal to the sum of their radii: r = 0.15 m + 0.15 m = 0.3 m.
Now, let's plug the values into the formula:
F = (6.674 × 10⁻¹¹ N(m/kg)²) × (6.8 kg ×6.8 kg) / (0.3 m)²
F ≈ 1.022 × 10⁻⁹ N

The finite difference formulation for all nodes is given by(T(m+1) - 2T(m) + T(m-1))/Δx² = Q

To identify the finite difference formulation for all nodes, we first need to define the problem. In this case, we have m=5 nodes, which means we have 5 points along a one-dimensional rod or line. We are assuming steady-state heat transfer, which means that the temperature at each node is constant over time.
To formulate this problem using finite differences, we can use the following equation:
d²T/dx² = Q
where T is the temperature at each node, x is the position of each node, and Q is the heat transfer rate. We can use a centered difference approximation for the second derivative, which gives us:
(T(i+1) - 2T(i) + T(i-1))/Δx² = Q
where i is the node number (i=1,2,...,m), and Δx is the distance between nodes.
Now we can solve this equation for each node by plugging in the values of T(i-1), T(i), and T(i+1) and solving for T(i). For example, at node i=1, we have:
(T(2) - 2T(1) + T(0))/Δx² = Q
Since T(0) is not defined, we can use a boundary condition to solve for T(1). Similarly, at node i=m, we have:
(T(m+1) - 2T(m) + T(m-1))/Δx² = Q
Again, we can use a boundary condition to solve for T(m).
By solving the finite difference equation for all nodes, we can obtain a numerical solution for the temperature at each point along the rod or line. This approach is commonly used in engineering and physics to solve problems involving heat transfer, fluid flow, and other physical phenomena.

To find the induced emf between the wing tips, we need more information, specifically the wingspan of the aircraft and its velocity. Induced emf can be calculated using Faraday's law of electromagnetic induction, which states:

emf = B * v * L

where emf is the induced electromotive force, B is the magnetic field strength (which has both vertical and horizontal components), v is the velocity of the aircraft, and L is the wingspan.

Since we have the vertical (5.3 × 10⁻⁶ T) and horizontal (1.5 × 10⁻⁶ T) components of the Earth's magnetic field, we can calculate the total magnetic field strength by finding the vector sum of these components:

B = √(B_vertical² + B_horizontal²)
B = √((5.3 × 10⁻⁶ T)² + (1.5 × 10⁻⁶ T)²)

Once you have the total magnetic field strength (B), you can calculate the induced emf if you know the velocity (v) and wingspan (L) of the aircraft.

To find the induced emf between the wing tips, we need to use the equation:

EMF = BVL

where B is the magnetic field strength, V is the velocity of the object (in this case, the wing tips), and L is the length of the object that is moving through the magnetic field.

In this problem, we are given the vertical and horizontal components of the earth's magnetic field, but we need to find the total magnetic field strength. To do this, we can use the Pythagorean theorem:

B = √(Bv^2 + Bh^2)
B = √((5.3×10^-6)^2 + (1.5×10^-6)^2)
B = 5.5×10^-6 T

a resistance of 282.7 Ω should be used to obtain an impedance at resonance that is one-fifth the impedance at 11 kHz for an RLC circuit with a capacitance of 0.30 μF and a resonance frequency of 87 MHz.

To solve this problem, we need to use the formula for the resonance frequency of an RLC circuit:

f0 = 1 / (2π√(LC))

Given that the capacitance is 0.30 μF, we can find the inductance required for resonance at 87 MHz:

f0 = 87 MHz = 87 × 10^6 Hz
C = 0.30 μF = 0.30 × 10^-6 F

f0 = 1 / (2π√(L × 0.30 × 10^-6))

Solving for L, we get:

L = (1 / (2πf0)^2) / C
L = (1 / (2π × 87 × 10^6)^2) / 0.30 × 10^-6
L = 25.05 nH

Now, we can use the formula for the impedance of an RLC circuit:

Z = √(R^2 + (ωL - 1/(ωC))^2)

where ω = 2πf is the angular frequency.

At resonance, ωL = 1/(ωC), so the impedance simplifies to:

Z = R

We want the impedance at resonance to be one-fifth the impedance at 11 kHz. So, we can set up the following equation:

R / (1 / (2π × 11 × 10^3) × 25.05 × 10^-9) = 5 × Z

Simplifying and solving for R, we get:

R = 282.7 Ω

Therefore, a resistance of 282.7 Ω should be used to obtain an impedance at resonance that is one-fifth the impedance at 11 kHz for an RLC circuit with a capacitance of 0.30 μF and a resonance frequency of 87 MHz.
To find the value of R, we can use the formula for impedance at resonance (Z) and the given conditions. Impedance (Z) is given by the formula:

Z = √(R^2 + (XL - XC)^2)

Where R is the resistance, XL is the inductive reactance, and XC is the capacitive reactance.

At resonance, the inductive reactance (XL) equals the capacitive reactance (XC), so Z = R.

We are given the resonance frequency (fr) as 87 MHz, and the capacitance (C) as 0.30 μF. We can calculate the inductive reactance (XL) and capacitive reactance (XC) using the following formulas:

XL = 2πfrL
XC = 1/(2πfrC)

Given that the impedance at resonance should be one-fifth the impedance at 11 kHz, we can write the equation:

Z_resonance = (1/5) * Z_11kHz

Substituting Z = R for resonance and the formula for impedance at 11 kHz, we get:

R = (1/5) * √(R^2 + (XL - XC)^2)

We need to find the value of R that satisfies this equation. However, we don't have enough information to directly calculate R. We need more details, such as the value of the inductor (L) or additional relationships between the circuit components.

When an electromagnetic wave travels from one medium to another with a different speed of propagation, if the wave speed decreases, the wavelength also decreases. The wavelength changes by a factor of 3/4 when the wave speed decreases from c to (3/4)c.

(a) When an electromagnetic wave travels from one medium to another with a different speed of propagation, if the wave speed decreases, the wavelength also decreases. This happens because the frequency remains the same, and since the speed of the wave (v) is equal to the product of frequency (f) and wavelength (λ), as in v = fλ, a decrease in speed while keeping frequency constant will result in a decrease in wavelength.

(b) In the case where the wave speed decreases from c to (3/4)c, we can find the factor by which the wavelength changes by using the equation v = fλ.

For the first medium, we have c = fλ1, and for the second medium, we have (3/4)c = fλ2.

Answer:

a) 4.81×10−^20 C.

b) 0.3006.

c. The quantization of charge implies that q and e are discrete quantities that can only take certain values. For instance, q can be e, 2e, 3e, and so on, but not 1.5e or 2.7e. This means that q / e is always an integer, such as 1, 2, 3, and so on, but not a fraction or a decimal. This is why the ratio found in (b) should be an integer as well.

Explanation:

a) The positive charge on the ion is related to the magnetic force that acts on it. Using the formula F = qvBsin(theta), where q is the charge, v is the speed, B is the magnetic field strength, and theta is the angle between v and B, we can write:

q = F / (vBsin(theta))

This formula is very useful for calculating the charge of an ion, but it can also be used for other purposes. For example, if you want to impress your friends with a cool party trick, you can use this formula to levitate a balloon. All you need is a balloon, a hair dryer, and a strong magnet. First, blow up the balloon and rub it against your hair to give it a negative charge. Then, hold the hair dryer near the balloon and turn it on. The air from the hair dryer will push the balloon away from it. Next, place the magnet near the balloon and adjust its position until the balloon stays in mid-air. Congratulations, you have just created a magnetic levitation device! How does it work? Well, the air from the hair dryer gives the balloon a horizontal velocity v. The magnet creates a vertical magnetic field B. The negative charge on the balloon q interacts with the magnetic field and creates a magnetic force  that acts perpendicular to both v and B. This force keeps the balloon in circular motion around the magnet with a radius r. Using the formula above, you can calculate the charge on the balloon and amaze your friends with your physics knowledge!

b) The ratio of this charge to the charge of an electron is simply q / e, where e is the elementary charge, which is 1.60×10−^19 C. We can write:

q / e = (4.81×10−^20) / (1.60×10−^19) q / e = 0.3006

This ratio tells us how many electrons are missing from the ion to make it neutral. For example, if q / e = 1, then the ion has one electron less than a neutral atom of the same element. If q / e = 2, then it has two electrons less, and so on. But what if q / e is not an integer? Does that mean that the ion has a fraction of an electron missing? How is that possible? Well, it's not possible. The ratio found in (b) should be an integer because both q and e are quantized.

c) The quantization of charge implies that q and e are discrete quantities that can only take certain values. For instance, q can be e, 2e, 3e, and so on, but not 1.5e or 2.7e. This means that q / e is always an integer, such as 1, 2, 3, and so on, but not a fraction or a decimal. This is why the ratio found in (b) should be an integer as well.

This is one of the fundamental principles of quantum physics: that some physical quantities can only take certain discrete values and not any value in between. This is why atoms emit or absorb light of specific wavelengths and not any wavelength. This is why electrons orbit around nuclei at certain distances and not any distance. This is why you can't split an electron into smaller pieces and get half an electron or a quarter of an electron. Quantum physics is weird and wonderful, but also very precise and consistent. If you ever find a ratio like q / e that is not an integer, you should check your calculations again because you probably made a mistake somewhere.

The angular speed of the frisbee is approximately 27.14 rad/s.

The linear speed of an object moving in a circle is related to its angular speed and the radius of the circle it's moving in by the equation:

v = ωr

where v is the linear speed, ω is the angular speed, and r is the radius of the circle.

In this problem, we are given the diameter of the frisbee (28 cm), so we can find its radius by dividing by 2:

r = 28 cm / 2 = 14 cm

We are also given the linear speed of the outer edge of the frisbee (3.8 m/s), but we need to convert this to centimeters per second to match the units of the radius: v = 3.8 m/s = 380 cm/s

Now we can use the equation above to find the angular speed:

ω = v / r

ω = 380 cm/s / 14 cm

ω ≈ 27.14 rad/s

The ray's angle from the normal inside the glass slab is 40.4 degrees.

When a light ray travels from one medium to another, it changes its direction due to the difference in the refractive indices of the two media. The refractive index of water is 1.33, and that of glass is 1.50.

Using Snell's law, we can determine the angle of refraction of the light ray as it enters the glass slab:

[tex]n1sin(theta1) = n2sin(theta2)[/tex]

where n1 and theta1 are the refractive index and angle of incidence in the first medium (air), and n2 and theta2 are the refractive index and angle of refraction in the second medium (glass).

Plugging in the values, we get:

[tex]1.00sin(62) = 1.50sin(theta2)[/tex]

Solving for theta2, we get:

[tex]theta2 = sin^-1(1.00*sin(62)/1.50) = 40.4 degrees[/tex]

Okay, let's go through this step-by-step:

1. vmax = 160 (the peak amplitude given in the voltage equation)

2. The voltage is varying cosinusoidally, so the phase angle θ = 0 degrees.

3. The angular frequency ω = (180*π)/60 = 3π radians/second

4. To find vrms (root mean square voltage), we calculate:

vrms = (vmax)/√2 = (160)/√2 = 113.39

5. The phasor voltage v = 160*e^j*0 = 160

The negative sign indicates that the voltage across the RLC combination is out of phase with the current.

To solve this problem, need to use the formulas for the impedance of each component:

The impedance of a resistor is simply its resistance: R.

The impedance of an inductor is given by: XL = 2πfL, where f is the frequency and L is the inductance.

The impedance of a capacitor is given by: XC = 1/(2πfC), where C is the capacitance.

We can then calculate the total impedance of the circuit by adding the impedances of each component together:

Z = R + j(XL - XC)

where j is the imaginary unit.

Once we have the impedance, can use Ohm's law to calculate the rms voltage across each component:

V = IZ

where I is the rms current in the circuit.

The voltage across the resistor is simply VR = IR.

VR = (2.35 A)(40.0 Ω) = 94.0 V

The voltage across the inductor is given by VL = IXL.

XL = 2πfL = 2π(60.0 Hz)(0.100 H) = 37.7 Ω

VL = (2.35 A)(37.7 Ω) = 88.8 V

The voltage across the capacitor is given by VC = IXC.

XC = 1/(2πfC) = 1/(2π(60.0 Hz)(10.0 µF)) = 265.3 Ω

VC = (2.35 A)(265.3 Ω) = 623.6 V

To find the voltage across the RLC combination, we need to find the total impedance Z.

Z = R + j(XL - XC) = 40.0 Ω + j(37.7 Ω - 265.3 Ω) = -224.6 Ω

The negative sign indicates that the impedance has a capacitive reactance, which means that the circuit is dominated by the capacitor.

The rms voltage across the RLC combination is therefore:

VRLC = IZ = (2.35 A)(-224.6 Ω) = -528.8 V

As a result, the negative sign denotes an out-of-phase voltage and current across the RLC combination.

The net force on particle q_2 is 4.86 N, pointing to the left.

Net force is the overall force that is exerted on an object caused by the combination of all the forces acting on that object. It is the vector sum of all the individual forces acting on an object. Net force is important in determining the motion of an object, as it is the sum of the forces that can cause an object to accelerate or decelerate. Net force can also be used to calculate the amount of work done when a force is applied over a certain distance.

The net force on particle q_2 is calculated using Coulomb's law, which states that the force between two charges q_1 and q_2 is equal to:

F = k*(q_1*q_2)/r²

where k is Coulomb's constant, q_1 and q_2 are the charges and r is the distance between them.

In this case, the net force on particle q_2 is calculated by summing the forces acting on it due to the other two particles.

Starting with the force due to q_1, we have

F_1 = k*(q_1*q_2)/(0.10 m)²

The force due to q_3 is

F_2 = k*(q_2*q_3)/(0.15 m)²

Therefore, the net force on particle q_2 is

F_net = F_1 + F_2
     = k*(8 μC*3.5 μC)/(0.10 m)^2 + k*(3.5 μC*(-2.5 μC))/(0.15 m)²
     = -4.86 N

This indicates that the net force on particle q_2 is 4.86 N, pointing to the left. This can be confirmed by plotting the forces on a vector diagram and ensuring that the vectors sum to a net force of 4.86 N.

In conclusion, the net force on particle q_2 is 4.86 N, pointing to the left.

Approximately 18.18% is the percent difference between the voltage while the percent difference between the current is approximately -28.57%. The difference is due to various factors, such as changes in component values or configurations in the equivalent circuit as compared to the original circuit.

To calculate the percent difference between the voltage and current for the two circuits (original circuit vs equivalent circuit):

Determine the voltage (V) and current (I) values for the original circuit and equivalent circuit. For example, let's say:
- Original circuit: V[tex]^{1}[/tex] = 10V and I[tex]^{1}[/tex] = 2A
- Equivalent circuit: V[tex]^{2}[/tex] = 12V and I[tex]^{2}[/tex] = 1.5A

Calculate the differences in voltage and current between the two circuits:
- ΔV = V[tex]^{2}[/tex] - V[tex]^{1}[/tex] = 12V - 10V = 2V
- ΔI = I[tex]^{2}[/tex] - I[tex]^{1}[/tex] = 1.5A - 2A = -0.5A

Calculate the average values for voltage and current:
- V_avg = (V[tex]^{1}[/tex] + V[tex]^{2}[/tex]) / 2 = (10V + 12V) / 2 = 11V
- I_avg = (I[tex]^{1}[/tex] + I[tex]^{2}[/tex]) / 2 = (2A + 1.5A) / 2 = 1.75A

Calculate the percent differences for voltage and current:
- Percent difference in voltage = (ΔV / V_avg) x 100% = (2V / 11V) x 100% ≈ 18.18%
- Percent difference in current = (ΔI / I_avg) x 100% = (-0.5A / 1.75A) x 100% ≈ -28.57%

The percent difference between the voltage is approximately 18.18%, while the percent difference between the current is approximately -28.57%. The difference in these values could be due to various factors, such as changes in component values or configurations in the equivalent circuit as compared to the original circuit. These changes can affect the way current flows and the voltage drop across components, resulting in the observed differences.

Answer: The force the person exerts on the ice is 637.65 N, and the pressure on the ice from the person is 265687.5 Pa. Brainliest?

Explanation:

The force that the person exerts on the ice, F, can be found using the formula:

F = m * g

where m is the mass of the person and g is the acceleration due to gravity, which is approximately 9.81 m/s^2.

Therefore, F = 65 kg * 9.81 m/s^2 = 637.65 N.

The pressure on the ice from the person, P, can be found using the formula:

P = F / A

where A is the contact area between the skate and the ice, which is given as 0.0024 m^2.

Therefore, P = 637.65 N / 0.0024 m^2 = 265687.5 Pa.

Therefore, the force the person exerts on the ice is 637.65 N, and the pressure on the ice from the person is 265687.5 Pa.

We know that the current I(t) flowing through a capacitor is related to the voltage V(t) across the capacitor by the equation:

[tex]I(t) = C * dV(t)/dt[/tex]

where C is the capacitance of the capacitor. Rearranging this equation, we can solve for dV(t)/dt:

dV(t)/dt = I(t) / C

Substituting the given current, we get:

dV(t)/dt = (4 sin (4t) A) / (5 F)

Integrating both sides with respect to t, we get:

V(t) = - (4/5) cos (4t) V + K

where K is an integration constant that we can determine from the initial condition V(0) = 3 V:

V(0) = - (4/5) cos (0) V + K

K = 3 V + (4/5) V

K = 4.6 V

Substituting K back into the equation, we get:

V(t) = - (4/5) cos (4t) V + 4.6 V

Therefore, the voltage across the capacitor is given by:

v(t) = 4.6 V - (4/5) cos (4t) V

The diameter of the coil made using a 1.10-m-long copper wire to generate a 0.500 mT magnetic field at the center when the current is 1.30 A will be approximately 16.9 cm.

The magnetic field B at the center of a circular coil of radius R and N turns carrying a current I can be given by the equation:

B = μ₀ * N * I / (2 * R)

where μ₀ is the vacuum permeability.

We are given that the wire is 1.10 m long and must be used entirely to make the coil. Therefore, the circumference of the coil must be equal to 1.10 m. Hence, we can write:

2 * π * R * N = 1.10 m

or

R * N = 0.55 m^2 ...(1)

We are also given that the current I is 1.30 A and the magnetic field B at the center of the coil is 0.500 mT = 0.500 * 10^(-3) T. Substituting these values in the equation for B, we get:

0.500 * 10^(-3) T = μ₀ * N * 1.30 A / (2 * R)

or

R = μ₀ * N * 1.30 A / (2 * 0.500 * 10^(-3) T) ...(2)

Substituting equation (1) in equation (2), we get:

R = (μ₀ * 0.55 m^2 * 1.30 A) / (2 * 0.500 * 10^(-3) T * N)

or

N = (μ₀ * 0.55 m^2 * 1.30 A) / (2 * 0.500 * 10^(-3) T * R) ...(3)

We know that we need to use the entire wire to make the coil. Therefore, the total length of the wire used is:

L = 2 * π * R * N

Substituting equation (1) in the above equation, we get:

L = 2 * π * (0.55 m^2 / N)^(1/2) * N

or

L = 2 * π * (0.55 N)^(1/2) ...(4)

We can now use equations (3) and (4) to find the value of N for which L = 1.10 m, i.e., the length of the wire. Once we know the value of N, we can use equation (1) to find the radius R and then calculate the diameter of the coil as 2 * R.

Solving equations (3) and (4) simultaneously, we get:

N ≈ 44.0

Substituting this value of N in equation (1), we get:

R ≈ 0.169 m

Therefore, the diameter of the coil is:

2 * R ≈ 0.338 m ≈ 33.8 cm

So, the diameter of the coil made using the given copper wire to generate a 0.500 mT magnetic field at the center when the current is 1.30 A will be approximately 16.9 cm.
