Can you explain the answer of this question below:
Let 19825_493f965b17f1e90d9c8381c8500ac576H and 19825_493f965b17f1e90d9c8381c8500ac576E respectively be the angular speeds of the hour hand of a watch and that of the earth around its own axis. Compare the angular speeds of the earth and hour hand of a watch.
  • A:
    19825_493f965b17f1e90d9c8381c8500ac576H =  19825_493f965b17f1e90d9c8381c8500ac576E
  • B:
    ωH = 219825_493f965b17f1e90d9c8381c8500ac576E
  • C:
    ωH = (1/2)19825_493f965b17f1e90d9c8381c8500ac576E
  • D:
    ωH = 419825_493f965b17f1e90d9c8381c8500ac576E
The answer is b.

Can you explain the answer of this question below:LetH andE respective...
Given,
Angular velocity of the hour hand-H
Earth’s speed around its own axis-E
So, time taken by hour hand to complete a rotation is=TH=12hr
Time taken by earth to complete a rotation =TE=24 hours
So,
ωEH =(2π/TE )/2π/TH=TH/TE=1/2
⇒ ωEH=1/2
⇒ 2 ωE= ωH
