Question

Which has a longer time period, a satellite revolving close or away from the surface of the earth?

Answer 1

Answer: away from surface

Explanation:

Answer 2

A satellite that is revolving closer to earth will have a smaller time period or period of revolution. Short distance results in a greater force of gravity and a shorter orbit...which inturn results in a larger velocity. A larger velocity in a short orbit means small period of revolution. Thus we can say that a satellite revolving away from the surface of earth has a longer time period.
