1. Radio signals travel at a rate of 3x10^7 meters per second. How many seconds will it take for a radio signal to travel from a satellite to the surface of the earth if the satellite is orbiting at a height of of 3.5x10^6 Meters?

Respuesta :

speed = 3*10⁷ m/sec
distance =3.5*10⁶m
time=distance/speed = 3.5*10⁶m/3*10⁷ m/sec ≈ 1.17/10 =0.117 sec
