This is more then likely wrong but for part B i said 70% of power had to be transferred back to maintain equilibrium so therefore 239.4 W/m^2
And for Part C I used T^4 = P/(e*"boltz constant"*Area)
Which then became
T = 4Sqrt(239.4 W/m^2/(0.602*5.67*10^-8*4*pi*6378000m^2)
Hey guys having some trouble with this question its a new topic in my course
The Earth receives solar radiation at a rate of 342 W/m2 averaged over the total surface of the Earth. About
30% of this radiation gets reflected back into space while the rest is absorbed. For the Earth to...
