The power radiated by the sun is 3.9 3 1026 W. The earth
Chapter , Problem 31(choose chapter or problem)
The power radiated by the sun is 3.9 3 1026 W. The earth orbits the sun in a nearly circular orbit of radius 1.5 3 1011 m. The earths axis of rotation is tilted by 278 relative to the plane of the orbit (see the drawing), so sunlight does not strike the equator perpendicularly. What power strikes a 0.75-m2 patch of fl at land at the equator at point Q?
