the speed of tip of hand is 360° per 60 minute
Length of the hours hand in a pendulum = 10cm
The distance travelled by the hour hand for one day = 2πr cm
=2× 22/7×10 cm
The time taken by the hours hand = 1 day = 24 hours = 60×60×24 seconds
speed of tip of the hour hand = distance / time
=2×22/7×10//60×60×24
= 1/10745 cm/s
