Question

The orbital velocity of an artificial satellite in a circular orbit is v.The orbital velocity of satellite orbiting at an altitude of half of the radius will be

Answer 1

Answer:

$\color{blue}{ANSWER}$

Orbital velocity is the velocity needed to achieve balance between gravity's pull on the satellite and the inertia of the satellite's motion -- the satellite's tendency to keep going. This is approximately 17,000 mph (27,359 kph) at an altitude of 150 miles (242 kilometers).
