1.	A clock contain hour’s hand of length 14 cm. Calculate the displacement produced by the tip of thehand in the time of 9 hours is
Answer» he LENGTH of the lour hand is 14 cm.To find:Displacement of the hour hand in 9 hours.Solution:1) The length of the hour hand would be the radius of the circular PATH covered by the hand of the clock.2) Hand covers the TIME of 9 hours so it will COVER 3/4 of the total distance.3) So the displacement will be 3/4(2πr)3/2×πr3/2×22/7×1466 cm.Displacement of the hour hand in 9 hours is 66 cm.
