Question

The ratio of an angular speed of hours hand and seconds hand of clock

Answer 1

Angular speed is equals to distance / time here distance is constant that is 2πr only time period of revolution is different. angular speed is inversely proportional to time hence let's consider Wh for hours hand. and Ws for second hand

then ratio will be Wh /Ws = 60 S / 12 hours ,,,,
= 60s / 12* 60* 60 seconds = 1 /720 .so
Wh / Ws = 1 / 720 this is the ratio of angular speed of hours hand and second hand of clock.
