Answer 1

Explanation:

To complete one second the arm of second moves360

∘

Angular speed is

60

2π

Hour hand completes 1 rotation 360

∘

in

12hrs

Angular speed is

12×3600

2π

Therefore the ratio of angular velocity is given as

60

2π

=

12×3600

2π

Hence the ratio of the angular speed of hour and seconds is1:720
