Problem 11: Gun sights are adjusted to aim high to compensate for the effect of gravity,__deleteda1e95d6bdd8fd52001 666cb4e43a9d922d8880f1022887403bfae 627e23f904bdeleted__ 0N86-C1-52-40-A837-22816 If a gun is sighted to hit targets that are at the same height as the gun and 125 m away at the same height, how low, as a positive number in meters, will the bullet hit if aimed directly at a target 185 m away

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?

Calculate a pendulums frequency of oscillation (in hz) if the pendulum completes one cycle in 0.5s.

Cyclotrons are widely used in nuclear medicine for producing short-lived radioactive isotopes. these cyclotrons typically accelerate h- (the hydride ion, which has one proton and two electrons) to an energy of 5 mev to 20 mev. this ion has a mass very close to that of a proton because the electron mass is negligible—about 1 2000 of the proton’s mass. a typical magnetic field in such cyclotrons is 1.9 t. (a) what is the speed of a 5.0-mev h-? (b) if the h- has energy 5.0 mev and b = 1.9 t, what is the radius of this ion’s circular orbit?
