1. an object rests on a ramp. as the high end of the ramp is raised further, the angle of inclination increases causing the object to start moving. with the help of a free-body diagram, explain why this happens.
2. In looking at a series of bright and dark fringes on a screen, how would one determine whether the pattern was created by a double-site or a single-site? why is there this difference in patterns?
