The type of energy that is produced by the system that is described is heat energy. The correct answer is D.
I want to say its cooled by reflection because of the foil, sun reflects off of the foil back into the atmosphere. I don't think it's conduction because I have the foil on my windows and it's never warm to the touch. it's not a liquid so I don't believe it's convection. The foil reflects the radiation so I don't think it's b, c or d. so I wanna say A but I'm not 100% sure
Perpendicular slope would be 1/3. so the equation will be Y=1/3x -4
