A hydrogen atom has its electron in the n state. = 1
(a) How much energy would have to be absorbed by the atom for it to become ionized from this level?
(b) What is the frequency of the photon that could produce this result?
A pulsar is a rapidly rotating neutron star that emits a radio beam the way a lighthouse emits a light beam. What is the pulsar's angular acceleration
As an example, consider a coil of diameter 2.00 cm with 72.0 turns that is rotated about an axis perpendicular to the field at a rate of 20.0 Hz. If the maximum induced emf in the coil is 6.00 V, find out the strength of the magnetic field.
