Question

Which of the following represents the time taken for a microwave signal from Earth to reach a geostationary satellite situated 36,000 km above the Earth's equator?

A) Approximately 0.12 seconds
B) Roughly 0.24 seconds
C) Around 0.06 seconds
D) About 0.48 seconds

Answer 1

The time taken for a microwave signal from Earth to reach a geostationary satellite situated 36,000 km above the Earth's equator is approximately 0.12 seconds.

Step-by-step explanation:

To calculate the time taken for a microwave signal from Earth to reach a geostationary satellite situated 36,000 km above the Earth's equator, we can use the formula:

Time = Distance / Speed

In this case, the distance is 36,000 km and the speed of light, which is the speed of electromagnetic signals, is approximately 300,000 km/s. Plugging these values into the formula, we get:

Time = 36,000 km / 300,000 km/s = approximately 0.12 seconds

Therefore, the correct answer is A) Approximately 0.12 seconds.
