The velocities of A, B, and C after the first three collisions are (1 - e)v, (1 - e)v, and (2e - 1)v respectively.

Let's denote the masses of the four balls as A, B, C, and D respectively. The velocity of each ball after the first three collisions can be determined using the equation of Conservation of Momentum:

The momentum of A + B before the collision = Momentum of A + B + C after the collision

mAvA + mBvB = mAv'A + mBv'B + mCv'C

Where v'A, v'B, and v'C are the velocities of A, B, and C respectively after the collision.

Since all four balls have the same mass, m, the equation simplifies to:
2mv = 2mv'A + 2mv'B + 2mv'C

Solving for v'A, v'B, and v'C gives

v'A = (1 - e)v

v'B = (1 - e)v

v'C = (2e - 1)v

Therefore, the velocities of A, B, and C after the first three collisions are (1 - e)v, (1 - e)v, and (2e - 1)v respectively.

The coefficients of friction for this scenario are μs = 0.4 and μk = 0.2.

The coefficient of static friction (μs) is the ratio of the maximum force of static friction (Fs max) that can be overcome between two solid surfaces in contact with each other, while the coefficient of kinetic friction (μk) is the ratio of the force of kinetic friction between two solid surfaces in contact with each other that are in motion. Both coefficients can be used to describe the amount of friction between two surfaces, which is dependent on the type of material and surface finish. The equation F = μN is used to calculate frictional forces, where F is the force of friction, μ is the coefficient of friction, and N is the normal force, which is equal to the weight of the object in question.

The normal force N, which is equal to the weight of the object, is determined using the equation N = mg, where m is the mass of the object and g is the acceleration due to gravity. Using this information, the coefficients of friction can be calculated. In this case, the block weighs 200 N and requires 80 N of force to overcome the static friction to get it moving. The normal force is equal to the weight, which is 200 N, so the coefficient of static friction is:

μs = Fs max /N= 80 N/200 N= 0.4. For the kinetic coefficient of friction, 40 N of force is required to keep the block moving at a constant velocity. Since the block is already moving, the maximum force of static friction does not apply, so the force of kinetic friction is used. Thus, the coefficient of kinetic friction can be calculated as follows: μk = kinetic friction/N = 40 N/200 N = 0.2

Some stars rise and set, while others remain in the sky all the time, depending on the observer's location on Earth.

This phenomenon occurs because Earth rotates on its axis, causing the stars to appear to move across the sky.
Stars that rise and set are called "circumpolar stars." These stars are visible above the horizon throughout the entire night, and their positions change due to Earth's rotation. For observers at the Earth's equator, all stars will appear to rise and set because they are equally distributed around the sky.

However, for observers at higher latitudes, some stars will never rise nor set. These stars are called "circumpolar stars." They are visible all year round and seem to circle around the celestial poles (North and South Poles). The closer an observer is to the poles, the larger the number of circumpolar stars.

In summary, whether stars appear to rise and set or remain in the sky depends on the observer's location on Earth. At the equator, all stars will appear to rise and set, while at higher latitudes, some stars will be circumpolar and stay visible in the sky all the time.

The statement that photons of ultraviolet radiation contain more energy than do photons of violet visible light is true.

Due to its shorter wavelengths than blue or violet light, ultraviolet radiation oscillates more quickly and has a higher energy content per photon than visible light.

Compared to visible light, UV light contains more energetic photons, but the quantity is governed by intensity, which is the number of photons released in a certain amount of time, such as from a lamp.

This is also known as the luminous flux or light flux.

The color of visible light depends on the energy of the photons that produce it. Higher energy (shorter wavelength) light is at the violet end of the visible light spectrum, whereas lower energy (longer wavelength) light is at the red end.

UV light has a shorter wavelength than violet visible light due to its increased intensity.

Static equilibrium means that all forces are equal, so to make this easiest you want to break F1 into it's horizontal and vertical components. As there are no other forces acting in the horizontal, we know the horizontal component of F1 is 40N.

Dynamic equilibrium is a state in which bodies are moving at a constant speed as opposed to static equilibrium, which is a state in which bodies are at rest (rectilinear motion). The total amount of forces exerted on them in both situations is zero.

When two forces are acting on an object that is in static equilibrium, it indicates that their sum is zero, which makes static equilibrium a useful analytical tool. You may create an equation to figure out the direction and strength of the unknown force if you know the direction and strength of one of the forces.

In this experiment, rubbing a plastic bag against wool allowed electrons to move back and forth between the two, creating a negative charge on the bag. When the negatively charged bag was brought close to the neutral PAN, the bag's negative charge attracted the PAN's electrons, separating the two charges and leaving the PAN with a positive charge. On touching the pan the surplus positive charge was neutralized, creating a spark.

When the pan was brought up to the nose a slight jolt was felt and a crackling sound was heard. This resulted in the excess charge in the pan being carried through the air to the nearest conductor, the person holding the pan.

1) The boiling point of water reduces by 3.28°C at 1,000 m above sea-level

2) The boiling point of water reduces by 6.56°C at 2,000 m above sea-level

Explanation:

The variation of the boiling point of water with elevation is given as follows

The boiling point reduces by 0.5°C for every 152.4 meter increase in elevation

At sea-level, the boiling point temperature of water = 100°C

1) At 1,000 m elevation, the boiling point temperature, T = 100 - (1,000/152.4) × 0.5 ≈ 96.72 °C

Therefore, the boiling point of water reduces by 100° - 96.72° = 3.28°C at 1,000 m above sea-level

2) At 2,000 m elevation, the boiling point temperature, T = 100 - (2,000/152.4) × 0.5 ≈ 93.44°C

The boiling point of water reduces by 100° - 93.44° = 6.56°C at 2,000 m above sea-level

A conductor refers to a material that allows an electric current to flow through it with ease. In other words, it has a low electrical resistance. Conductors are materials that have a high number of free electrons that are able to move freely through the material. Examples of conductors include copper, aluminum, gold, and silver. These materials are commonly used in the electrical industry to make wires and other electrical components that need to conduct electricity. In addition to materials, a conductor can also refer to a person or an organization that is responsible for directing or leading an orchestra or a choir. In this context, a conductor is in charge of maintaining the ensemble's rhythm and intonation, and interpreting the score in a way that brings out the music's emotional content and intended meaning.

(i) The magnitude of the electric field created by a charged conductor is given by the formula E = \(\frac{kq}{r}\), where k is the Coulomb constant, q is the charge, and r is the distance from the center of the sphere.

For a good conductor, like sphere A, the charge will be distributed evenly on the surface of the sphere. So, the electric field at a radial distance of 6cm will be Eₐ = \(\frac{kq}{r^{2} }\) = \(k\frac{210^{-6} }{(619^{-2} )}^{2} =\frac{k}{72}\)

For an insulator, like sphere B, the charge is distributed uniformly throughout its volume. The electric field at a radial distance of 6cm will be \(E_{b}\)=  \(\frac{kq}{r^{2} }=k\frac{210^{-6} }{(619^{-2} )}^{2} =\frac{k}{72}\)

As we can see, the magnitudes of the electric fields created by both spheres are equal, so the answer is (b) \(E_{a} =E_{b}\)

(ii) For the radius of 4cm, the electric field created by sphere A and sphere B will

\(E_{a} =\frac{kq}{r^{2} }=k\frac{210^{-6} }{(410^{-2} )^{2} } =\frac{k}{16}\\E_{b} =\frac{kq}{r^{2} }=k\frac{210^{-6} }{(410^{-2} )^{2} } =\frac{k}{16}\\\)

As we can see, the magnitudes of the electric fields created by both spheres are equal at a radius of 4cm, so the answer is (b) \(E_{a} =E_{b}\)

If a clock appears to run slow by a factor of 10, it means that the clock's speed is 1/10th the speed of the observer. Therefore, the speed of the clock is one-tenth the speed of the observer.

The speed of the clock cannot be determined based solely on the information given about its time dilation factor. Without additional information about the clock's actual velocity or the reference frame of the observer, it is not possible to calculate its speed accurately. The time dilation factor of 10 suggests that the clock is experiencing significant time dilation due to its motion relative to the observer, indicating that it is moving at a substantial velocity.
