Question

Calculate the angular velocity of the neptune (orbital period of 165 earth period) in its orbit around the sun.

Answer 1

The correct answer is: Angular velocity =
`1.208 * 10^(-9)` rad/s

Step-by-step explanation:
The angular velocity is given as:
ω =
`(2\pi)/(T)` --- (1)

Where T = 165 * (365 days) * (24 hours/day) * (60 minutes/hour) * (60 seconds/minute) = 5203440000 s

Plug in the value in (1):
ω =
`(2\pi)/(5203440000) = 1.208 * 10^(-9)` rad/s
