Homework Help: Physics

Posted by Elizabeth on Tuesday, March 26, 2013 at 4:32pm.

The power radiated by the sun is 3.90 1026 W. The earth orbits the sun in a nearly circular orbit of radius 1.50 1011 m. The earth's axis of rotation is tilted by 27 relative to the plane of the orbit (see the drawing), so sunlight does not strike the equator perpendicularly. What power strikes a 0.575-m2 patch of flat land at the equator at point Q?
