33. 2075 set a q. no. 102 the sun is a black body of surface
temperature about 6000k. if sun's radius is 7x108m.
calculate the energy per second radiated from its surface.
the earth is about 1.5x1011 m from the sun. assuming all
the radiation from the sun falls on the surface of sphere of
this radius, estimate the energy per second per meter?
