and a moment of inertia of 1.94 × 10-46 kg m?
about an axis through its centre perpendicular to
the lines joining the two atoms. Suppose the mean
speed of such a molecule in a gas is 500 m/s and
that its kinetic energy of rotation is two-thirds of its
kinetic energy of translation. Find the average angular
velocity of the molecule.
In a Maxwell's wheel experiment, the mass of the wheel is 450 gram, and the
radius of the spindle going through the center of the wheel is 3 mm. A student
lets the wheel fall 30 cm, and finds out that the speed of the center of mass is
0.15 m/s. What is the moment of inertia of this wheel? Take g=9.81 m/s^2.

This result is obtained by using integral calculus to add up the contributions of all the atoms in the disk. The factor of 1/2 reflects the fact that some of the atoms are near the center and some are far from the center; the factor of 1/2 is an average of the square distances.
