Question

angular velocity of the hour hand ratating about its own axis​

Answer 1

Answer:

Time period = 12hours

T = 12 × 60 ×60 = 43200

f = 1/43200

w = 2πf

w = π/21600

or

w = 2π/T

Answer 2

Explanation:

hour hand of a watch complete one rotation in 12 hours while earth complete one rotation in 24 hours so angular velocity of hour hand is double the angular velocity of the earth
