Answer
$\omega=0.105 \frac{rad}{s}$
Work Step by Step
The second hand of clock completes a round trip in 60 seconds.
Therefore, the angular speed $\omega=\frac{2\pi}{60}$
When we put the value of $\pi$ in the above formula,
$\omega=\frac{2(3.1416)}{60}$
$\omega=0.105 \frac{rad}{s}$
Therefore, the angular speed of the second hand is $0.105 \frac{rad}{s}$.
