Which illustration represents the arrangement of particles in a liquid?

Answer:

V/Ve = 1.1

Explanation:

The formula to find the escape velocity of an object at a distance from Earth's Surface is given as follows:

Ve = √[2GM/R]

where,

Ve = escape velocity = ?

G = Universal Gravitational  Constant = 6.67 x 10⁻¹¹ N.m²/kg²

M = Mass of Earth = 5.97 x 10²⁴ kg

R = Radius of Earth = 6.37 x 10⁶ m

Therefore,

Ve = √[2(6.67 x 10⁻¹¹ N.m²/kg²)(5.97 x 10²⁴ kg)/(6.37 x 10⁶ m)]

Ve = 11.2 x 10³ m/s = 11.2 km/s

Hence, the ratio will be:

V/Ve = (12.3 km/s)/(11.2 km/s)

V/Ve = 1.1

Answer:

6.9m/s

Explanation:

Given parameters:

Acceleration of the object  = 4m/s²

Distance = from x; 2m to x; 8m

Unknown:

Average velocity  = ?

Solution:

From the given parameters, we use the right motion equation to solve the problem.

   v² = u² + 2aS

v is the final velocity

u is the initial velocity

a is the acceleration

 S is the distance covered

 Distance  = 8m - 2m  = 6m

 Initial velocity  = 0m/s

The final velocity gives us the average velocity in this problem;

       v² = 0² + (2 x 4 x 6) = 48

      v = √48  = 6.9m/s

A sound box or sounding box (sometimes written soundbox) is an open chamber in the body of a musical instrument which modifies the sound of the instrument, and helps transfer that sound to the surrounding air. Objects respond more strongly to vibrations at certain frequencies, known as resonances.

Explanation:

Answer:

it is attracted to negative pole

A copper wire will get attracted to negative pole of magnetic field when it

is moved across it

The copper wire has free electrons in it which when moved across the

magnetic field will result in the movement of the electrons to the negative

pole of the magnetic field.

This is because unlike poles attract and like poles repel. Copper is a metal

and positively charged and so it gets attracted to the negative pole during

electron flow.

Answer: e. P/2

Explanation:

For ideal gases, we have the relation:

P*V = n*R*T

where:

n =  number of mols

R = Gas constant

T = temperature

V = volume

P = pressure.

We know that for sample A, we have n moles, a temperature T and a volume V, then the pressure of this sample will be:

Pa = (n*R*T)/V.

For sample B, we have:

n/2 moles, temperature T/2 and a volume V/2, then the pressure will be:

Pb = (n/2)*R*(T/2)*(2/V) = (n*R*T/V)*(2/4)

and:

(n*R*T/V) = Pa

Then we can replace it and we get:

Pb = (n*R*T/V)*(2/4) = Pa*(2/4) = Pa*(1/2) = Pa/2.

Then the correct option is e.

Answer:

a) The x and y components of the momentum are [tex]8.731\,\frac{kg\cdot m}{s}[/tex] and [tex]-11.661\,\frac{kg\cdot m}{s}[/tex], respectively.

b) The magnitude and direction of its momentum are approximately 14.567 kilogram-meters per second and 306.823º.

Explanation:

a) The vectorial equation of momentum is represented by the following expression:

[tex]\vec p = m\cdot \vec v[/tex] (1)

Where:

[tex]\vec p[/tex] - Vector momentum, measured in kilogram-meters per second.

[tex]m[/tex] - Mass of the particle, measured in kilograms.

[tex]\vec v[/tex] - Vector velocity, measured in meters per second.

If we know that [tex]m = 2.93\,kg[/tex] and [tex]\vec v = 2.98\,\hat{i}-3.98\,\hat{j}\,\,\,\left[\frac{m}{s} \right][/tex], then the momentum is:

[tex]\vec p = (2.93)\cdot (2.98\,\hat{i}-3.98\,\hat{j})\,\,\,\left[\frac{kg\cdot m}{s} \right][/tex]

[tex]\vec p = 8.731\,\hat{i}-11.661\,\hat{j}\,\,\,\left[\frac{kg\cdot m}{s} \right][/tex]

The x and y components of the momentum are [tex]8.731\,\frac{kg\cdot m}{s}[/tex] and [tex]-11.661\,\frac{kg\cdot m}{s}[/tex], respectively.

b) The magnitude and direction of momentum are represented by the following expressions:

[tex]\|\vec p \| = \sqrt{p_{x}^{2}+p_{y}^{2}}[/tex] (2)

[tex]\theta = \tan^{-1}\left(\frac{p_{y}}{p_{x}} \right)[/tex] (3)

Where:

[tex]\|\vec p\|[/tex] - Magnitude of momentum, measured in kilogram-meters per second.

[tex]\theta[/tex] - Direction of momentum, measured in sexagesimal degrees.

If we know that [tex]p_{x} = 8.731\,\frac{kg\cdot m}{s}[/tex] and [tex]p_{y} = -11.661\,\frac{kg\cdot m}{s}[/tex], then the magnitude and direction of momentum are, respectively:

[tex]\|\vec p\| = \sqrt{\left(8.731\,\frac{kg\cdot m}{s} \right)^{2}+\left(-11.661\,\frac{kg\cdot m}{s} \right)^{2}}[/tex]

[tex]\|\vec p\| \approx 14.567\,\frac{kg\cdot m}{s}[/tex]

[tex]\theta =\tan^{-1}\left(\frac{-11.661\,\frac{kg\cdot m}{s} }{8.731\,\frac{kg\cdot m}{s} } \right)[/tex]

[tex]\theta \approx 306.823^{\circ}[/tex]

The magnitude and direction of its momentum are approximately 14.567 kilogram-meters per second and 306.823º.

Explanation:

In an inelastic collision, the momentum remains conserved while the kinetic energy is not conserved.

(i) Here, a small sports car runs into the machine from behind.

Due to the conservation of momentum, it remains conserved. It means their momentum changes are the same size.

Hence, the correct option is (c).

(ii) The car is moving faster than the tractor. A faster moving object will lose more energy as compared to the other. It means car's most of the energy is converted to internal energy. The car will have a a larger change in kinetic energy. Hence, the correct option is (a).

Answer:

c it is not accelerating on it's on but gravity pulls it there for velocity increases.

As an object falls, velocity increases and acceleration is unchanged. Therefore, option C is correct.

The term velocity is defined as the direction of the movement of the body or the object.

Speed is fundamentally a scalar quantity. Velocity is, in essence, a vector quantity. It is the rate at which distance changes. It is the displacement rate of change.

The velocity of something is the rate at which it moves in a specific direction. For example, the speed of a car driving north on a highway or the speed of a rocket after launch. The scalar denotes that the absolute magnitude of the velocity vector is always the speed of motion.

Thus, it is not accelerating on it's on, but gravity pulls it there as velocity increases.

Answer:

B. Shear Modulus

Explanation:

In this scenario, the friction force between the sliding block and the floor causes the block to deform.

Hence, the elastic modulus which describes the relationship between stress and strain for a block of iron sliding across a horizontal floor is Shear Modulus.

Shear Modulus can be defined as the ratio of shear stress to shear strain with respect to a physical object.

This ultimately implies that, Shear Modulus arises as a result of the application of a shear force on an object or body which eventually leads to its deformation. Thus, this phenomenon is simply used by scientists to measure or determine the rigidity of an object or body.

Mathematically, Shear Modulus is given by the formula;

[tex] G = \frac {Fl}{ADx} [/tex]

Where;

G is the Shear Modulus.

F is the force applied to the object.

A is the area of the object.

l is the length of the object.

Dx is the change in length.

Shear Modulus is measured in Pascals.

"A hydraulic turbine converts the energy of flowing water into mechanical energy. A hydroelectric generator converts this mechanical energy into electricity.

A cell phone more likely to break when dropped from a higher height than a lower one because it has more potential energy at high height.

Potential energy is the energy stored by an object as a result of its position relative to other objects, internal tensions, electric charge, or other reasons.

Potential energy is commonly defined as an object's gravitational potential energy, the elastic potential energy of an extended spring, and the electric potential energy of an electric charge in an electric field. The joule is the SI unit of energy.

Although it has connections to the Greek philosopher Aristotle's concept of potentiality, the word potential energy was coined by the 19th-century Scottish engineer and physicist William Rankine.

Explanation:

momentum is mass times velocity. since the velocity changes by 2 m/s. you just take the difference from final velocity to beginning velocity.

4kg*12m/s = 48 kg*m/s

4kg*10m/s = 40 kg*m/s

48kg*m/s - 40 kg*m/s = 8kg*m/s
