You've been told the Earth puts out 0.070 [W/m squared] as a global average. What would you predict would be the surface heat flux in [W/m squared] from a planet that is 70% larger in radius than the Earth, but has the same bulk composition. You can assume the only source of internal heat is radioisotopes (ignore tides, etc.).
I think you are in my class, do you get number three on the exam?
