Question

Q. calculate angular velocity of :--
a) second hand of a watch.
b) minute hand of watch.
c) hour hand of a watch.
d) revolution of earth around sun.​

Answer 1

Answer:

The ratio of angular speed of a second-hand to the hour-hand of a watch is. A. 3600 : 1. B ... Therefore angular speed = 602πrad/sec.

Top answer

We know that a second hand of the clock takes 60sec (1 min) to cover an angular distance of 2 π radians (360°).Therefore angular speed = 2π60 rad/sec
