During a testing process, a worker in a factory mounts a bicycle wheel on a stationary stand and applies a tangential resistive force of 135 N to the tire's rim. The mass of the wheel is 1.90 kg and, for the purpose of this problem, assume that all of this mass is concentrated on the outside radius of the wheel. The diameter of the wheel is 60.0 cm. A chain passes over a sprocket that has a diameter of 8.75 cm. In order for the wheel to have an angular acceleration of 3.70 rad/s2, what force, in Newtons, must be applied to the chain?

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?
