A thin layer of gasoline floating on water appears brightly colored in sunlight. From where do the colors come?
1..the interference of light waves reflected from the opposite surfaces of the gasoline film
2.the interference of the various wavelengths of sunlight reflected at the air‑gasoline boundary
3.the interference of light waves of similar frequencies created by the dispersion of the sunlight by the gasoline film
4.the interference of light waves refracted by the opposite surfaces of the gasoline film

Asmall object with mass 0.200 kg swings back and forth on the lower end of a light rope that is 3.00 m long. the upper end of the rope is attached to the ceiling. as the object swings through its lowest position, where the rope is vertical, the speed of the object is 5.80 m/s. at this point in the motion, what is the tension in the rope? (use g = 9.80 m/s2.)

A14 kg rock starting from rest free falls through a distance of 5.0 m with no air resistance. find the momentum change of the rock caused by its fall and the resulting change in the magnitude of earths velocity. earth mass is 6.0 * 10^24 kg. show your work assuming the rock earth system is closed.
