Observe the second hand of the clock.what about his moves and speed explain in science |
|
Answer» 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 |
