Aproton of mass m is at rest when it is suddenly struck head-on by an alpha particle (which consists of 2 protons and 2 neutrons) moving at speed v. if the collision is perfectly elastic, what speed will the alpha particle have after the collision? (assume the neutron's mass is equal to the proton's mass.) a) zero b) 2v/3 c) 3v/5 d) 5v/3

Electromagnetic induction. a coil of wire contains n turns and has an electrical resistance r. the radius of each turn is a. initially, inside the coil there exists a uniform magnetic field of magnitude b0 parallel to the axis of the coil. the magnetic field is then reduced slowly. the current induced in the coil is i. how long does it take for the magnitude of the uniform field to drop to zero?
