Earth completes one revolution round the sun in 365.25 days. What is the angular velocity ?

Text Solution

AI Generated Solution

To find the angular velocity of the Earth as it revolves around the Sun, we can follow these steps: ### Step 1: Understand the formula for angular velocity The angular velocity (ω) is defined as the angular displacement (Δθ) divided by the time taken (t) to complete that displacement: \[ \omega = \frac{\Delta \theta}{t} \] ...
