Problem 7 Geosynchronous Satellites. Many satellites are moving in a circle in the earth's equatorial plane. They are at such a height above the earth's surface that they always remain above the same point. 1. Find the altitude of these satellites above the earth's surface. (Such an orbit is said to be geosynchronous.) 2. Explain, with a sketch, why the radio signals from these satellites cannot directly reach receivers on earth that are north of 81.3° N latitude.

Problem 7
Geosynchronous Satellites. Many satellites are moving in a circle in the earth's equatorial plane.
They are at such a height above the earth's surface that they always remain above the same point.
1. Find the altitude of these satellites above the earth's surface. (Such an orbit is said to be
geosynchronous.)
2. Explain, with a sketch, why the radio signals from these satellites cannot directly reach receivers on
earth that are north of 81.3° N latitude.
