The distance from earth to a NASA satellite traveling through the solar system is 6.0 * 109m. A command is sent to the satellite from scientists on earth to send back telemetry data. Assuming the satellite instantly transmits the data when it receives the command, how much time (in s) would pass before the scientists receive the data?

the signal it takes 40 s to get the answer

Explanation:

As the satellite is in space the speed of radiation (waves9 is the speed of light in a vacuum, which is constant 3. 108 m / s, so we can use the uniform motion ratios to find the time.

v = d / t

t = d / v

t = 6.0 109 / 3. 108

t = 2 101 s

t = 20 s

This is the time it takes to get the signal from the earth to the satellite and it takes the same time to return, so since they send the signal it takes 40 s to get the answer
