Question

Communications satellites are placed in orbits so that they always remain above the same point of the earth's surface.A Part completeWhat must be the period of such a satellite?Express your answer in hours to the nearest integer.TT = 24 h Previous Answers CorrectB What is its angular velocity?

Answer 1

Answer:

24 hours

$7\times 10^{-5}\ rad/s$

Explanation:

If a satellite is in sync with Earth then the period of each satellite is 24 hours.

$T=24\times 60\times 60\ s$

Angular velocity is given by

$\omega=\dfrac{2\pi}{T}\\\Rightarrow \omega=\dfrac{2\pi}{24\times 60\times 60}\\\Rightarrow \omega=7\times 10^{-5}\ rad/s$

The angular velocity of the satellite is $7\times 10^{-5}\ rad/s$
