Question

The angular speed of daily rotation of earth in rad.s-1 is?

Answer 1

it takes the Earth approximately 23 hours, 56 minutes and 4.09 seconds to make one complete revolution (360 degrees). This length of time is known as a sidereal day. The Earth rotates at a moderate angular velocity of 7.2921159 × 10−5 radians/second. Venus has the slowest angular velocity (2.99 × 10−7rad/sec) and Jupiter has the fastest (1.76 × 10−4rad/sec).
