Please help with the solution

5.3 A sphere of radius 0.5 m at T s = 27C and emissivity 0.85 is in a box with walls at T w = 77C. What is the rate at which: A. Radiant energy is emitted by the sphere B. Radiant energy is absorbed by the sphere C. Find the net power absorbed by the sphere. 5.4 A power tower absorbs solar energy that heats molten salt to 1000C. The salt then radiates like a blackbody. A. Qualitatively (no numbers) sketch the radiation spectrum emitted versus wavelength. B. Calculate the wavelength of the peak of your curve
