The tungsten filament of an electric lamp has a length of 0.5 m and a diameter 6x10m. The power rating of the lamp is 60 W. Assuming the radiation from the
filament is equivalent to 80%
that of a perfect black body radiator at the same
temperature, estimate the steady temperature of the filament.
(Stefan constant -5.7x10 %WmrK')

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?
