Assume: The system shown below starts from rest and there are no frictional forces opposing the motion of the system. The dolly and its wheels have negligible mass. The acceleration of gravity is 9.8 m/s2. 28.8 N 350 N If a person pulls on the rope with a constant force what is the acceleration of the system: Answer in units of m/s-

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?
