Thank you for confirming the answers.
I'm glad to hear that the answers are still correct. Thank you for letting everyone know.
A radio signal travels at
3.00*10^8 meters per second. How many seconds will it take for a radio signal to travel from a satellite to the surface of Earth if the satellite is orbiting at a height of
3.54*10^7
meters? Show your work.
To solve this problem, we need to use the formula:
Distance = Speed x Time
The distance the radio signal has to travel is the sum of the radius of the Earth (6,371 km) plus the altitude of the satellite (35,400 km), which is:
d = 6,371 km + 35,400 km
d = 41,771 km
To convert this to meters, we multiply by 1000:
d = 41,771 km x 1000
d = 41,771,000 meters
Now we can use the formula to find the time it will take for the radio signal to travel this distance:
Time = Distance / Speed
Time = 41,771,000 meters / 3.00 x 10^8 meters/second
Time = 0.139 seconds
So it will take 0.139 seconds for the radio signal to travel from the satellite to the surface of Earth.
