(a) What is the period of rotation of Earth in seconds? (b) What is the angular velocity of Earth? 6? (c) Given that Earth has a radius of 6.4×10? m at its equator, what is the linear velocity at Earth’s surface?

Solution 4PE Step-by-step solution Step 1 of 3 (a) The time for one complete rotation of an object is period. The rotation of the earth around its axis is 24hours Convert time period of earth from hour to sec. Hence period of rotation of earth in sec is . Step 2 of 3 (b) Frequency is inverse of period The angular velocity of rotation is The angular velocity of the earth is equal to .
