Nuclear physics

The isotope helium-6 undergoes beta decay. Write the reaction equation, and determine the identity of the daughter nucleus.

physics

A bicycle wheel consist of a rim ( radius R = 0. 40 m ) and essintially massless spokes. Soppose we mount the bycle wheel on the wall. so that the wheel is parallel to the wall. Is it free to spin around its center, but not freee to translate. A very light string is wrapped around the rim and a mass m + 0. 80 kg is attached to the end of the string. The mass is then released and falls 1.5 m in 0.78 s Determine the mass of the rim. Determine the final angular velocity of the wheel Through how many rotation did the wheel spin? calculate the work done by the mass on the wheel A solid cylinder of mass M and raduis R is rolling without slipping towards a semicircular track. The cylinder... click for more

Properties of nuclei

Singly ionized carbon is accelerated through 1000 V and passed into a mass spectrometer to determine the isotopes present. The magnetic field strength in the spectrometer is 0.200 T. (a) determine the orbit radii for the 12C and 13C isotopes as they pass through the field. (b) Show that the ratio of radii may be written in the form r1/r2 = the square root of m1/m2.

atomic physics

Calculate the classical frequency for the light emitted by an atom. To do so, note that the frequency of revolution is v/2pir, where r is the Bohr radius. Show that as n approches infinity in f= 2pi2mk2e4/h3 times 2n-1/(n-a)2 n2 the expression varies as 1/n3 and reduces to the classical frequency.

Nuclear power eactor: what is the change in the mass of the nuclear fuel due to the energy being taken from the reactor?

A nuclear power reactor generates 1.0e9 W of power. In one year, what is the change in the mass of the nuclear fuel due to the energy being taken from the reactor?
