Answer:

We conclude that if a flat piece of paper or blowing ball is dropped from the same height, They would hit the ground at the same time.

Thus,

option a) is correct.

Explanation:

When there is no air in the space, it is basically a vacuum.

In other words, the vacuum can be termed as a 'space devoid of matter'.

So, when there is no air in space, it means there is no force that can act on the body.

Therefore, no matter what objects (heavy or light) we may drop from the same height, they would all hit the ground at the same time.

As there is no force that can act on an object in the vacuum, it means every object in the vacuum seems to stand still while falling.

Therefore, we conclude that if a flat piece of paper or blowing ball is dropped from the same height, They would hit the ground at the same time.

Thus,

option a) is correct.

A negative test charge experiences a force to the right as a result of an electric field. Which is the best conclusion to draw

zaharov [31]

Answer:

The electric field points to the left because the force on a negative charge is opposite to the direction of the field.

Explanation:

In an electric field, a positive charge has tendency to move from high to low potential and hence experience the electric force in the direction of electric field since electric field lines are directed from high to low potential.

In an electric field, a negative charge has tendency to move from low to high potential and hence experience the electric force in the direction opposite to electric field since electric field lines are directed from high to low potential.This phenomenon happened because The electric field from a positive charge will points away from the charge while the electric field from a negative charge will points toward the charge.

Part D

Brrunno [24]

Answer:

i. The magnetic force of repulsion.

ii. The magnetic force of attraction.

Explanation:

A magnet is a material that has the attraction and repulsion capability. Magnets has two poles, north and south, thus would attract or repel another magnet in its neighborhood. It can either be a permanent or temporal magnet, and attracts ferrous metals.

i. In the case of two combinations where two ends are the same, it could be observed that the two ends (poles) repels each other. Thus since like poles repels, magnetic force of repulsion is felt.

ii. In the case of one combination in which the two ends are different, the two ends (poles) attract. Since unlike poles attracts, magnetic force of attraction is observed.

photon strikes the surface of tungsten and an electron is emitted. what is the maximum possible speed of the electron?

zalisa [80]

Answer: The maximum possible speed v is √2( hν - Ф ) / m

Explanation: You could be referring to the provided explanation, despite the fact that the question isn't comprehensive. When a photon collides with the surface of any metal, it transmits all of its energy to the electron in the atom. The collision causes the electron to travel with a certain amount of kinetic energy. This is referred to as the photoelectric effect. The maximum kinetic energy is calculated using Einstein's equation for the photoelectric effect:

K.E. = hν - Ф

½ mv² = hν - Ф

Hence the maximum possible speed is:

v = √2( hν - Ф ) / m
