Question

If Earth completes one revolution in 24 hours, what is the angular displacement made by Earth in one hour. Express your answer in both radian and degree.

Answer 1

Answer:

Pai/12 radian

Explanation:

Angular displacement by Earth in one hour =pai/12 radian

Answer 2

Dear Student,

◆ Answer -

Angular displacement = 15° = π/12 rad

● Explanation -

Time period of revolution of earth is given as 24 hours.

Time period = 24 hours

Angular displacement in 1 hour is given by -

Angular displacement = time elapsed / time period × 360

Angular displacement = 1/24 × 360

Angular displacement = 15°

We can convert this to radian by -

Angular displacement = 15 × 2π/360

Angular displacement = π/12 rad

Hope this helps you...
