The power radiated by the sun is 3. 9 × 1026 W. The earth orbits the sun in a nearly circular orbit of radius 1. 5 × 1011 m. The earth's axis of rotation is tilted by 23. 4° relative to the plane of the orbit (see the drawing), so sunlight does not strike the equator perpendicularly. What power strikes a 0. 30-m2 patch of flat land at the equator at point Q?
