What is the ratio of angular speed of hour hand of clock and angular speed of earth on its own axis?

Open in App

Solution

The second hand of a clock takes 60 seconds to complete one rotation. Its angular speed is 0.105 rad /s. ... Its angular speed is 1.455 x 10^-4 rad /s. The earth takes 24 hours to complete one rotation about its axis. The angular speed of the earth of itsrotation about its axis is 7.273 x 10^-5 rad /s.
