What component of fitness should you work on every time you exercise?

Answer: current I= 2 A

Explanation: when resistors are in series current I is same

Through each resistor. Potential drop along resistor R is

ΔV= IR. then I = ΔV/R = 6V/3Ω

Three resistors: R1 = 5 Ω,R2 = 3 Ω, and R3 = 4 Ω are connected in series to each other. A voltmeter connected in parallel to resistor R2 measures a voltage of 6 Volts, then the current flowing through the battery would be 2 Ampere.

Resistance is the obstruction of electrons in an electrically conducting material.

As given in the problem ,Three resistors: R1 = 5 Ω,R2 = 3 Ω, and R3 = 4 Ω are connected in series to each other. A voltmeter connected in parallel to resistor R2 measures a voltage of 6 V.

By using Ohm's Law,

V = IR

6 Volt = Electric current × 3 Ohms

Electric current = 6 volt / 3 Ohm's

                          = 2 Ampere

Thus, the current flowing through the battery would be 2 Ampere.

The charge on each ball is 6.1 ×10⁻⁸ C.

The definition of force in physics is: The push or pull on a massed object changes its velocity.

An external force is an agent that has the power to alter the resting or moving condition of a body. It has a direction and a magnitude. A spring balance can be used to calculate the Force. The Newton is the SI unit of force.  Force is a vector quantity and it has both magnitude and direction.

Let the balls have equal charge of q. Then, electrostatic force acting on each particle = √3 q²/r² dyne =  √3 q²/15² dyne =0.0076 q².

Weight of each ball = 13.3 ×980 dyne = 13034 dyne.

As the electrostatic force and the weight acts perpendicular to each other.

Hence, 0.1/√3 = 0.0076 q²/13034

q = 6.1 ×10⁻⁸ C

Hence, the charge on each ball is  6.1 ×10⁻⁸ C.

Answer: [tex]0.985\times 10^{-4}\ T[/tex]

Explanation:

Given

Electron is accelerated 3.5 kV potential difference

Distance between plates d=29 mm

The potential difference between plates is V=100 V

here, the kinetic energy of an electron is acquired through a potential difference of 3.5 kV

[tex]\Rightarrow \dfrac{1}{2}m_ev^2=e\times 3.5\times 10^3\\\\\Rightarrow v=\sqrt{\dfrac{2\times 3.5\times 10^3e}{m_e}}=\sqrt{\dfrac{7\times 10^3\times 1.6\times 10^{-19}}{9.1\times 10^{-31}}}\\\\\Rightarrow v=\sqrt{1.23\times 10^{15}}=3.5\times 10^7\ m/s[/tex]

To move in a straight line Force due to magnetic field must be balanced by force due to charge

Answer:

equipment for the measurement of microwave L bands with a range between 1 GHz and 2 GHz.

Explanation:

The electromagnetic spectrum can be calculated with the relationship between the speed of light, its wavelength and its frequency.

         c = λ f

For reasons of analysis and equipment used, it is artificially divided into ranges, with poorly defined limits and in some cases with overlaps between some.

For the case of analysis, f = 1.41 10⁹ Hz, we have the range called

* Microwave for f> 3 108 Hz to approximately f <3 1011 Hz

For the lower part of the frequency 3 10⁸ <f <3 10⁹ Hz we have UHF television channels and cell phones and military communications.

As the frequency observed by the researchers is in the UHF range, it is possible that they are using microwave equipment for communications, specifically equipment for the measurement of microwave L bands with a range between 1 GHz and 2 GHz.

Increasing the number of resistors in a parallel branch, decreases the total resistance of the system.

Parallel resistive circuit is one where the resistors are connected to the same two points (or nodes) and is identified by the fact that it has more than one current path connected to a common voltage source.

As more and more resistors are added in parallel to a circuit, the equivalent resistance of the circuit decreases and the total current of the circuit increases.

The answer is C I believe

Refers to the attachment for the answer.

Let us assume that the object of mass m is kept on the Inclined plane.

Now, there will act one force called as Component of the Weight along the Incline which is given by the Relation,

mgsinθ,

where θ is the angle which the incline makes with the surface or Angle of the Incline.

Now, If there will be no friction and the object is moving along the incline

Force = mgsinθ

⇒ ma = mgsinθ

∴ a = gsinθ

This case is valid when the angle of the Incline is greater than the angle of repose, which means the object is moving with no cause or acing of the force.

But sometimes when the object does not move without the action of force, I mean that the angle of repose is greater than the angle of the incline, then we need to apply the force so that the object can move then,

Force applied = mgsinθ

∴ a = gsinθ

It will change the cases when friction is involved.

Now, For velocity, It can be found by using the equation of Motions. Time, Distance or initial velocity, etc must be given if the question will be asked related to the velocity. So by using them, you can find that.

Answer:

T = 2.83701481512 seconds

Explanation:

Hi!

The formula that you will want to use to solve this question is:

[tex]T = 2\pi *\sqrt{\frac{L}{g} }[/tex]

T--> period

L --> length of the pendulum

g --> acceleration due to gravity (9.8m/s^2)

since we know that the mass of the bob at the end of the pendulum does not affect the period of the pendulum, we can go ahead and ignore that bit of information (unless, of course, the weight causes the pendulum to stretch)

so now we can plug in our given info into the formula above and solve!

T = 2*pi * sqrt(2/9.8)

T = 2.83701481512 seconds

*Note*

- I used 3.14 to pi, if you need to use a different value for pi (a longer version, etc) your answer will be slightly different

Answer:

a. 0.332 W/m² b. 11.2 V/m c. 15.8 V/m

Explanation:

(a) the average intensity of the light,

Intensity, I = P/A where P = average power = 150.0 W and A = area through which the power emits = 4πr² where r = distance from bulb = 6 m.

So, I = P/A = P/4πr²

Substituting the values of the variables into the equation, we have

I =  P/4πr²

I =  150.0 W/4π(6 m)²

I =  150.0 W/4π(36 m²)

I =  150.0 W/452.39 m²

I =  0.332 W/m²

(b) the rms value of the electric field,

Since Intensity, I = E²/cμ₀ where E = rms value of electric field, c = speed of light = 3 × 10⁸ m/s and μ₀ = permeability of free space = 4π × 10⁻⁷ H/m.

Making E subject of the formula, we have

E² = Icμ₀

E = √(Icμ₀)

Since I = 0.332 W/m², substituting the other terms into the equation, we have

E = √(0.332 W/m² × 3 × 10⁸ m/s × 4π × 10⁻⁷ H/m.)

E = √(0.332 W/m² × 3 × 10⁸ m/s × 4π × 10⁻⁷ H/m.)

E = √(12.5 × 10)

E = √125 V/m

E = 11.18 V/m

E ≅ 11.2 V/m

(c) the peak value of the electric field.

The peak value of electric field, E' is gotten from E = E'/√2 where E = rms value of electric field.

So, E' = √2E

= √2 × 11.2 V/m

= 15.81 V/m

≅ 15.8 V/m

Explanation:

Answer:

the correct answer is C

Explanation:

For this exercise we can use the conservation of angular momentum, let's define a system formed by the disk and the other body, so that the torques during the collision have been internal and the moment is conserved.

Initial instant. Before placing the second body

          L₀ = I₁ w₁

Final moment. Right after placing the body

         L_f = (I₁ + I₂) w

the moment of inertia of the ring with respect to an axis passing through its center is tabulated

         I_{cm} = m r²

we use the parallel axes theorem to find the moment of inertia about an axis passing through one end

        I₁ = I_{cm} + m d²

where d is the distance from the center of mass to the new axis

        d = r / 2

we substitute

        I₁ = mr² + m (r/2)²

        I₁ = 5/4 m r²

The second body does not specify a specific shape, so we can assume it to be punctual

        I₂ = m’ (2r)²

        I₂ = 4 m’ r²

in the exercise indicate that

        m ’= m / 4

        I₂ = m r²

how the moment of inertia is conserved

        L₀ = L_f

        I₁ w₁ = (I₁ + I₂) w

        5/4 m r² w₁ = (5/4 m r² + m r²) w

        5/4 m r² w₁ =9/4 m r² w

        w = 5/9 w₁      

we calculate

         w = 5/9 12

         w = 6.67 rad / s

having the initial and final angular velocities we can find the kinetic energy of the hoop

         K₀ = ½ I₁ w₁²

         K_f = ½ (I₁) w2

the energy ratio is

        [tex]\frac{K_f}{K_o}[/tex] = [tex]\frac{w^2}{w_1^2}[/tex]

        \frac{K_f}{K_o} = (6.67 / 12)²

        \frac{K_f}{K_o} = 0.309

        [tex]\frac{K_f}{K_o} %[/tex] = 31%
