The angular speed of seconds needle in a mechanical watch is
The angular speed of seconds needle in a mechanical watch is
$\frac{\pi }{{30}}\,rad/s$
$2\pi \,rad/s$
$\pi \,rad/s$
$\frac{{60}}{\pi }\,rad/s$
The angular speed of seconds needle in a mechanical watch is
$\omega = \frac{{2\pi }}{T} = \frac{{2\pi }}{{60}} = \frac{\pi }{{30}}\,rad/s$
