It takes 23 hours 56 minutes and 4 seconds for the earth to make one revolution (mean sidereal day). What is the angular speed of the earth

The angular speed of the Earth is approximately radians per second.

Explanation:

We suppose that Earth rotates at constant angular speed. From Rigid Body Physics, we remember that angular speed of the planet (), measured in radians per second, is:

(Eq. 1)

Where is the period, measured in seconds.

Therefore, the angular speed of the planet is:

The angular speed of the Earth is approximately radians per second.

answer: d. a cme increases the amount of energy in the solar wind

explanation:

coronal mass ejections, also called cmes, are large clouds of plasma and magnetic field that erupt from the sun. only when the cloud is aimed at earth will the cme hit earth and therefore cause impacts. high-speed solar wind streams come from areas on the sun known as coronal holes.
