Bill and Nageen have each built an electric motor and they are testing them by having them lift boxes. Bill's motor lifts a box 0.39 metres in 2 seconds. Nageen's motor lifts the same box 0.35 metres in 2 seconds. Whose motor has applied more power to the box?

Bill's motor

Explanation:

Bill's motor lifts a box 0.39 metres in 2 seconds.

Nageen's motor lifts the same box 0.35 metres in 2 seconds.

Power = Work done/time

or

Power of bill's motor,

Power of Nageen's motor,

So, Bill's motor applied more power to the box.

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.
