2. Wavg = Delta Theta / Delta Time

Delta Theta is in radians

3. Since the Earth rotates once during a day, the delta theta equals 2 Pi radians.

Time = 60 seconds (in a minute) * 60 minutes (in an hour) * 24 hours (in a day) = 84600 seconds.

2 Pi radians / 84600 seconds = 7.27 * 10^-5 rads/sec

Appartenly this is wrong accoring to the homework program WebAssign. What is wrong with my work?

Also, I got 1.99 * 10^-7 rad/sec for the angular velocity of the earth around the sun, which is apparently also wrong.

Help?
