Alaser beam enters a 12.0 cm thick glass window at an angle of 33.0° from the normal. the index of refraction of the glass is 1.41. at what angle from the normal does the beam travel through the glass? how long does it take the beam to pass through the plate?

Acar traveling at 22 m/s starts to decelerate steadily. it comes to a complete stop in 15 seconds. what is it’s acceleration?

It may seem strange that the selected velocity does not depend on either the mass or the charge of the particle. (for example, would the velocity of a neutral particle be selected by passage through this device? ) the explanation of this is that the mass and the charge control the resolution of the device--particles with the wrong velocity will be accelerated away from the straight line and will not pass through the exit slit. if the acceleration depends strongly on the velocity, then particles with just slightly wrong velocities will feel a substantial transverse acceleration and will not exit the selector. because the acc

What are the dimensions of the cross section that passes through the points a, f, g, and d?
