Engineers are testing a new thin-film coating whose index of refraction is less than that of glass. They deposit a 560-nmnm-thick layer on glass, then shine lasers on it. A red laser with a wavelength of 640 nmnm has no reflection at all, but a violet laser with a wavelength of 400 nmnm has a maximum reflection. How the coating behaves at other wavelengths is unknown.

An ascending elevator, hanging from a cable, is coming to a stop. part a part complete identify all forces acting on the elevator from the list below. select all that apply. select all that apply. kinetic friction normal force tension weight static friction submitprevious answers correct part b draw a free-body diagram of the object. draw the vectors starting at the black dot. the location and orientation of the vectors will be graded. the exact length of your vectors will not be graded but the relative length of one to the other will be graded.
