A group of engineers is preparing a satellite to land by moving it 10% closer to Earth in each rotation. Which statement is correct about the rotational inertia of the satellite?
O Rotational inertia first decreases and then increases as the satellite is ready to land.
O Rotational inertia decreases proportional to the decrease in the radius of rotation.
O Rotational inertia increases proportional to the decrease in the radius of rotation.
O Rotational inertia does not change because it is conserved

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?
