Coherent light with wavelength 601nm passes through two very narrow slits, and the interference pattern is observed on a screen a distance of 3.00 m from the slits. The first-order bright fringe is a distance of 4.84 mm from the center of the central bright fringe.
For what wavelength of light will the first-order dark fringe (the first dark fringe next to a central maximum) be observed at this same point on the screen?
A 200-kg crate is pushed horizontally with a force of 715 N. If the coefficient of friction is 0.20, compute the acceleration of the crate.
How strong is the electric field between the plates.
A gymnast with mass m1 = 43 kg is on a balance beam that sits on (but is not attached to) two supports. The beam has a mass m2 = 108 kg and length L = 5 m. Each support is 1/3 of the way from each end. at first the gymnast stands at the left end of..
