A communications satellite is in a synchronous orbit that is 3.47

Solutions

Expert Solution

Note that the distance to be travelled is from A to B, then B to C.          
          
Cutting the figure into 2 right triangles, and using Pythagorean theorem,          
          
AB = AC =    1745009.943   m  
          

Thus, the total distance is the sum of AB and Ac,          
          
d =    3490019.885   m  
          

Thus, as light travels at c = 3E8 m/s, then t = d/c:          
          
t =    0.0116    s   [ANSWER]

A communications satellite is in a synchronous orbit that is 3.09×107m directly above the equator. The satellite is located midway between Quito, Equador, and Belem, Brazil, two cities almost on the equator that are separated by a distance of 3.48×106m. Calculate the time it takes for a telephone call to go by way of satellite between these cities. Ignore the curvature of the earth.

A geosynchronous communications satellite in stationary orbit is used to relay radio messages from one point to another around the earth’s curved surface. Apply Newton’s second law to the satellite to find its altitude in meters above the earth’s surface. RE = 6.38 × 106 m, mE = 5.97 × 1024 kg, and G = 6.674 × 10−11 Nm2/kg2.
