revolution defination

It is the time taken by a satellite to complete one revolution around the Earth. Circumference of a circle of radius R + h is 2 p (R+h). Let T be the time period, v the velocity and h the height of the satellite above the Earth's surface. Substituting in the equation, we get ..
