In three situations, a single force acts on a moving particle. Here are the velocities (at that instant) and the forces:
(1) v = (-4i^) m/s, F = (6i^ - 2j^) N
(2) v = (2i^ - 3j^) m/s, F = (-2j^ + 7k^) N
(3) v = (-3i^ + 1j^) m/s, F (2i^ + 6j^) N
Rank the situations according to the rate at which energy is being transferred, greatest transfer to the particle ranked first, greatest transfer from the particle ranked last.

The law of the conservation of momentum says that the total momentum of any closed and isolated system cannot

Acyclotron is used to produce a beam of high-energy deuterons that then collide with a target to produce radioactive isotopes for a medical procedure. deuterons are nuclei of deuterium, an isotope of hydrogen, consisting of one neutron and one proton, with total mass 3.34×10−27kg. the deuterons exit the cyclotron with a kinetic energy of 6.40 mev .a-what is the speed of the deuterons when they exit? b-if the magnetic field inside the cyclotron is 1.25 t, what is the diameter of the deuterons' largest orbit, just before they exit? c-if the beam current is 350 μa how many deuterons strike the target each second?
