(a) What is the period of rotation of Earth in seconds? (b) What is the angular velocity of Earth? (c) Given that Earth has a radius of 6.4×106 m at its equator, what is the linear velocity at Earth’s surface?

Step 1 of 4 </p>

We have to express period of rotation of earth in seconds.after that we have to find the angular velocity of the earth and linear velocity of the earth.

Step 2 of 4</p>

The time taken by the earth to complete one rotation about its own axis is called period of rotation of earth.

The earth takes 24 hours (but exactly 23 hours 56 minutes 4 secs )to complete one rotation.

Now we have to convert hour to sec

=24 hours(3600 s/1 hr)

=86,400 s

So the period of rotation of earth is 86,400 s.
