A500n person stands 2.5m from a wall against which a horizontal beam is attached. the beam is 6m long and weighs 200n. a cable is attached to the free end of the beam and makes an angle of 45 to the horizontal and is attached to the wall.
1)determine the magnitude of the tension of the cable.
2)determine the reaction force that the wall exerts on the beam.

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?
