Two airplanes leave an airport at the same time. The velocity of the first airplane is
680 m/h at a heading of 57.7◦. The velocity
of the second is 580 m/h at a heading of 119◦. How far apart are they after 2.4 h? Answer in units of m.

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?
