The sun is 1.5 1011 m from the earth.
(a) Over what surface area is solar radiation spread at thisdistance?
(b) What is the total power radiated by the sun? (The sun deliversenergy to the surface of the earth at a rate of approximately 1400W/m2.)
(c) Treating the sun as a body of emissivity 1, estimate itstemperature. The sun's radius is 6.96 108 m.
