A6.00 kg object is lifted vertically through a distance of 5.25 m by a light string under a tension of 80.0 n. find: (2 marks) a. the work done by the force of tension, b. the work done by gravity, and c. the final speed of the object if it starts from rest.

Which describes increasing the efficiency of energy resource

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?
