Question

Radio signals travel at a rate of 3 × 10^8 meters per second. How many seconds would 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 3.6 × 10*7 meters?

A.) 8.3 seconds
B.) 1.2 × 10^–1 seconds
C.) 1.08 × 10^16 seconds
D.) 10.8 × 10^15 seconds

Answer 1

The time it takes for a radio signal to travel from a satellite to the Earth's surface, given the speed of radio signals and the satellite's orbit height, is calculated as 1.2 × 10⁻¹ seconds.

Step-by-step explanation:

To calculate the time it takes for a radio signal to travel from a satellite to the surface of the Earth, we use the formula:

Time = Distance / Speed

Given that the radio signals travel at a rate of 3 × 10⁸ meters per second, and the satellite is orbiting at a height of 3.6 × 10⁷ meters, we can plug these values into our formula:

Time = (3.6 × 10⁷ meters) / (3 × 10⁸ meters per second)

Time = (3.6/3) × 10⁷⁻⁸ seconds

Time = 1.2 × 10⁻¹ seconds

Therefore, the correct answer is B.) 1.2 × 10⁻¹ seconds.
