MY NOTES ASK YOUR TEACHER A geosynchronous Earth satellite is one that remains above the same point on Earth (provided it orbits in the equatorial plane in the same direction as Earth's rotation). Such orbits are useful for communication and weather observation. Calculate the radius, in meters, of such an orbit.
