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?

An insulated thermos contains 148 g of water at 72.7 Ėc. you put in a 11.7 g ice cube at 0.00 Ėc to form a system of ice + original water. the specific heat of liquid water is 4190 j/kgā¢k; and the heat of fusion of water is 333 kj/kg. what is the net entropy change of the system from then until the system reaches the final (equilibrium) temperature?

Two masses are connected by a rope that hangs over a pulley as shown below. the pulley is a uniform cylinder of radius ķ
=0.381meters and mass ķ=3.1ķķ. initially ķ"is on the ground and ķ#rests 2.5 meters above the ground. if the system is released, use conservation of energy to determine the speed of ķ#just before it strikes the ground. assume the pulley bearing is frictionless.
