An airplane was moving 50 mys to the north relative to the air at landing. The wind was blowing 5 m/s toward the south relative to the ground. What was the speed of the airplane relative to the ground at the time of landing?
10 m/s
45 m/s
55 m/s
250 m/s

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?
