Space probes may be attached to their launchers by exploding bolts, which can be used to separate the parts after takeoff. suppose a 4800-kg satellite uses this method to separate from the 1400-kg remains of its launcher, and that a total of 4850 j of energy is supplied to the two parts by the explosion. this process is "perfect" in the sense that the energy is transferred entirely to the motion of the system, rather than any deformations or other internal energy changes.

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?
