Several days after snowfall , the roofs of some homes on your street have almost no snow on them, while the roofs on other homes are still covered. assuming they have all received the same amount of sunlight, give one reason for this observation related to thermal energy & insulation.

Calculate the minimum energy required to remove one proton from the nucleus 126c. this is called the proton-removal energy. (hint: find the difference between the mass of a 126c nucleus and the mass of a proton plus the mass of the nucleus formed when a proton is removed from 126c.) express your answer with the appropriate units. emin e m i n = nothing nothing request answer part b how does the proton-removal energy for 126c compare to the binding energy per nucleon for 126c, calculated using eb=(zmh+nmn−azm)c2?
