Question

Ratio of angular speed of seconds hand to hour hand

Answer 1

Answer:

What is the ratio of the angular speed of the hour and second hands of a clock? We know that a second hand of the clock takes 60sec (1 min) to cover an angular distance of 2π radians (360°). For an hour hand to complete 1 rotation i.e 2π radians it takes 12hrs ( 12×3600 seconds). Finally the ratio is 21600/30 = 720:1.
