If the length of the day is T, the height of that TV satellite above the earth's surface which always appears stationary from earth, will be :

The height of a communication satellite from the earth's surface is about

When the height of a satellite increases from the surface of the earth.

The height of a geostationary satellite from the surface of the earth is

An artificial satellite is moving in a circular orbit around the earth with a speed equal to half the magnitude of escape velocity from the earth. (i) Determine the height of the satellite above the earth's surface. (ii) If the satellite is stopped suddenly in its orbit and allowed to fall freely onto the earth, find the speed with which it hits the surface of the earth.
