he sun radiates like a perfect blackbody with an emissivity of exactly 1.
(a) Calculate the surface temperature of the sun, given it is a sphere with a 7.00 ✕ 108 m radius that radiates 3.80 ✕ 1026 W into 3 K space.
K
(b) How much power does the sun radiate per square meter of its surface?
W/m2
(c) How much power in watts per square meter is this at the distance of the earth, 1.50 ✕ 1011 m away? (This number is called the solar constant.)
