1. as part of their training, air force pilots make two practice landings with instruc- tars, and are rated on performance. the instructors discuss the ratings with the pilots after each landing. statistical analysis shows that pilots who make poor land ings the first time tend to do better the second time. conversely, pilots who make good landings the first time tend to do worse the second time. the conclusion: crit icism the pilots while praise makes them do worse. as a result, instructors were ordered to criticize all landings, good or bad. was this warranted by the facts? answer yes or no, and explain briefly.

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?
