In order to move a box filled with equipment to the second story loft in the warehouse, several students built a ramp or inclined plane. there was some disagreement on the height and material for the ramp. the loft height was 2.5 meters. sara suggested a very long ramp, approximately 25 meters long. the other students disagreed, insisting it would take too much effort to push the box that distance and the ramp should be much shorter and steeper. instead they built a ramp 10 meters in length. what comments would you make to the students based solely on the mechanical advantage of an inclined plane?

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?
