Question 1077792: How many seconds (angle) of rotation does the Earth complete in one second (time)?
I cannot understand this. Please help me. Thanks. Found 2 solutions by addingup, ikleyn:Answer by addingup(3677) (Show Source): You can put this solution on YOUR website! The earth completes a rotation every 24 hours, and a complete circle is 360 degrees:
360/24 = 15 degrees every hour
1 hour = 60 minutes x 60 seconds = 3,600 seconds
15/3,600 = 0.0041667 degrees per second.
One whole rotation is 360 degs = 360*60*60 seconds (angular seconds).
24 hours = 24*60*60 seconds (time seconds).
You want the ratio = = 15.
Answer. In its daily rotation around the axis the Earth makes turn in 15 angular seconds per second.
