A box of mass m = 19.5 kg m=19.5 kg is pulled up a ramp that is inclined at an angle θ = 23.0 ∘ θ=23.0∘ angle with respect to the horizontal. The coefficient of kinetic friction between the box and the ramp is μ k = 0.335 μk=0.335 , and the rope pulling the box is parallel to the ramp. If the box accelerates up the ramp at a rate of a = 2.69 m/s 2 a=2.69 m/s2 , calculate the tension F T FT in the rope. Use g = 9.81 m/s 2 g=9.81 m/s2 for the acceleration due to gravity.

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?
