A13.0 kg wheel, essentially a thin hoop with radius 1.80 m, is rotating at 469 rev/min. it must be brought to a stop in 16.0 s. (a) how much work must be done to stop it? (b) what is the required average power? give absolute values for both parts.

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?
