Question

The angular velocity of seconds hand in a wall clock is​

Answer 1

Answer:0. 42 rad/s.

Explanation:

Answer 2

Angular Velocity(ω) is defined as the "rate of change of angular displacement(θ)."

Therefore, ω=θ/t

Calculation:

Given: Second-hand clock

The time that is taken to complete one revolution,

t = 60 seconds

Rotation angle(θ) = 2π rad

hence, angular speed(ω) of a second hand =

2π/60 = π/30 rad/s.
