Answer 1

A “satellite orbiting” at an altitude at “half of the earth’s radius” is

Explanation:

The orbital velocity at height h above the earth surface is,

Orbital velocity just above the earth surface is (V)

Orbital velocity at height of half of earth radius

Where,

Orbiting at an altitude at “half of the earth’s radius” is,
