The air is less dense at higher elevations, so skydivers reach a high terminal speed. The highest recorded speed for a skydiver

As per Einstein's theory of special relativity, the light speed in a vacuum remains constant regardless of the observer's speed. Therefore, the response should be A) 0.1c (one-tenth the speed of light)

Answer:

Explanation:

Given that the charge starts from rest and at point B has gained kinetic energy K = 4.8 J

we can apply the principle of conservation of mechanical energy, indicating that the increase in kinetic energy equals the reduction in electrostatic potential energy.

Thus, we can represent this as

Answer:

If the starting and ending points are identical, the overall work equals zero.

Explanation:

Option (D) is correct.

A force is considered conservative when the work performed by it while moving an object from point A to point B does not rely on the path taken and remains consistent across all paths. The work done is determined solely by the initial and final locations of the particle. Thus, when the initial and final positions in a conservative field coincide, the work is said to be zero.
