Glare appears on a computer screen when light from the surroundings reflects off of the screen’s surface. some computer screens have a special coating to reduce glare. which best explains how the coating works? a: the coating absorbs light that shines on it and prevents the light from reflectingb: the surface of the coating is rough, so light that shines on it gets scattered in many directions. c: the coating bends light that passes through it and prevents the light from reaching the user’s eyesd: the surface of the coating allows light from the room to pass through but blocks the light from the screen.

If the temperature were raised very high, classically what would we expect the heat capacity per object to be for this one-dimensional system? give a numerical value. chigh t = __ j/k/object (one reason for the discrepancy is that the high-temperature limit assumes that the number of oscillators is large (n > > 1), which is not the case in this tiny system.)

When a spring is compressed, the energy changes from kinetic to potential. which best describes what is causing this change? work power gravitational energy chemical energy
