Question

15. If Earth completes one revolution in
24 hours, whatisthe angular displacement
made by Earth in one hour. Express your
answer in both radian and degree.​

Answer 1

Answer:

earth completes one revolution in 24 hours . so, angular displacement in 1 hour = 360/24 = 15° . 15° = 15π/180 = π/12 radian.

_____________________________________________________

Angle in 24 Hours = 360°

Angle in one Hour =

$\frac{360}{24}$

= 15°

1 degree =

$\frac{\pi}{180} \: rad$

15° =

$\frac{\pi}{180} \times 15$

Answer

$\frac{ \pi}{12} \: radian$
