A device uses an AC voltage of 4320 V, which is obtained from a standard 120.0 V outlet by means of a transformer. If the primary coil has 21 turns, how many turns are in the secondary coil?
A proton moving in a magnetic field experiences a magnetic force of 17 N at 26o at one instant in time. At the same instant in time, an electron moving with the same speed experiences the same magnetic field. Compare the magnetic force experienced by the electron to that of t...
