Question

define rotation. what is the speed of rotation at the equated ?
​

Answer 1

Answer:

A rotation is a circular movement of an object around a center of rotation. The geometric plane along which the rotation occurs is called the rotation plane, and the imaginary line extending from the center and perpendicular to the rotation plane is called the rotation axis. The earth rotates once every 23 hours, 56 minutes and 4.09053 seconds, called the sidereal period, and its circumference is roughly 40,075 kilometers. Thus, the surface of the earth at the equator moves at a speed of 460 meters per second--or roughly 1,000 miles per hour.

Answer 2

Answer:

The daily movement of Earth on its imaginary axis from West to east is called rotation. To covers a distance of 40,000 km of rotation of the length of equational diameter,the earth takes 24 hours. So,the speed of rotation there would work out to be 1674 km per hour.
