Answer:0.84cm/s

Explanation:the length of second hand clock become the radius of the circle in which the second hand is revolving

For linear velocity the distance is 2Πr

r=8cm

t=60s(as we know second hand complete one complete revolution in 60s )

v =d/t

v=2Πr/60

v=0.84cm/s

Answer:

The speed of the second hand (the one which shows seconds) is 0.008m/s. Why do clocks go faster the higher up they come? The hour hand of the clock is 2.5 inches long.
