Two blocks are pushed together, compressing a spring between them by compression distance x. after being released, the spring falls to the ground, and the carts with masses ma and mb move along a frictionless track reaching a max height ha and hb respectively. which variable increasing would decrease ha
write an expression for maximum heigh ha in terms of ma mb k x and g

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?
