Question

What is a period of revolution of the earth satellite?

Answer 1

1. Satellites are objects that revolve around a planet.
2. Those satellites that revolve around the planet earth, are called earth satellites.
3. These satellites can be manmade or natural, like the moon.
4. The time it takes for a satellite to complete one complete revolution is called the time period or the period of revolution of the satellite.
5. $$\begin{gathered} TimeperiodofrevolutionT=2\mathrm{\pi }\sqrt{\frac{R_h}{g}} \\ where{R}_{h}isheightofsatellitefromearth\text{'}ssurface,gisaccelerationduetograity \end{gathered}$$
   where, $T$ is the time period and $r$ is the semi-major axis of elliptical orbit around the sun.
