Electromagnetic radiation from the sun reaches the earth at a rate 1370W/m^2. The radius of the sun is 6.96x10^8m and the distance from the center of the sun to earth is 1.5x10^11. Assume solar radiation reaches sun as single wave.  A) what is the electric field amplitude of solar radiation when it reaches earth ?   b)what is total energy radiated by sun in 2.5 seconds  give answer in J   c) if we assume sun emits like a black oft with emissivity e=1 calculate the temperature on the surface of Sun in Celsius  Please show work
