Auniform bar has two small balls glued to its ends. the bar is 2.00 m long and has mass 4.00 kg, while the balls each have mass 0.300 kg and can be treated as point masses. find the moment of inertia of this combination about an axis: (a) perpendicular to the bar through its center. (b) perpendicular to the bar through one of the balls. (c) parallel to the bar through both balls. (d) parallel to the bar and 0.500 m from it.

Amichelson interferometer operating at a 600 nm wavelength has a 3.02-cm-long glass cell in one arm. to begin, the air is pumped out of the cell and mirror m2 is adjusted to produce a bright spot at the center of the interference pattern. then a valve is opened and air is slowly admitted into the cell. the index of refraction of air at 1.00 atm pressure is 1.00028.how many bright-dark-bright fringe shifts are observed as the cell fills with air?
