Question

The Angular velocity of
a) The minute handle of watch
b)Second handle of watch
c) Hour handle of watch​

Answer 1

Answer:

B. second handle of watch

Answer 2

Explanation:

The second hand goes through 2π radians in 1 min, or 2π radian/60 seconds, so ω = π/30 rad.s-1 = 0.03 rad.s-1. The minute takes one hour = 60 s/min × 60 min = 3600 s to go around, ... The hour hand of the clock does not actually have a uniform instantaneous angular velocity but we can find its average angular velocity.
