A geosatellite is 3600 km above the earth's surface. It is rotating in a circular orbit at a height of . Satellite's orbital...

Suppose the orbit of a satellite is exatly 35780 km above the earth's surface. Determine the tangential velocity of the satellite.

If a satellite orbits as close to the earth's surface as possible,

if a satellite orbits as close to the earth's surface as possible.

Taking the earth to be a uniform sphere of radius 6400 km and the value of g at the surface to be 10ms^(-2) , calculate the energy needed to raise a satellite of mass 2000 kg to a height of 800 km a above the earth's surface and to set it into circular orbit at that altitude.

The orbital velocity of an artifical satellite in a cirular orbit above the earth's surface at a distance equal to radiu of earth is v. For a satellite orbiting at an altitude half of earth's radius, orbital velocity is

A remote sensing satellite of the earth revolves in a circular orbit at a height of 250 km above the earth's surface. What is the (i) orbital speed and (ii) period of revolution of the satellite ? Radius of the earth, R=6.38xx10^(6) m, and acceleration due to gravity on the surface of the earth, g=9.8 ms^(-2) .

Define orbital velocity of a satellite. Derive expressions for the orbital velocity of a satellite. Show that the escape velocity of a body from the earth's surface is sqrt2 times its velocity in a circular orbit just above the earth's surface.

The ratio of energy required to raise a satellite to a height h above the earth surface to that required to put it into the orbit is

An artifical satellite of mass 'm' is moving in a circular orbit aroundthe earth. The height of the satellite above the surface of the earth is R. Suppose that it stops suddenly in its orbit and falls freely under gravity. With what speed it will strike the surface of the earth?
