Question

What can you say about the angular speed of an hour hand as compared to that of the Earth's rotation about its axis ?

Answer 1

Answer:

Hour-hand of a watch completes one rotation in 12 hours, while earth completes one rotation in 24 hours. So angular velocity of hour-hand is double the angular velocity of the earth. This is because ω = 2 π T , where T is the time taken to complete one rotation and ω is the angular velocity
