A1.50-m string of weight 0.0125 n is tied to the ceiling at its upper end, and the lower end supports a weight w. ignore the very small variation in tension along the length of the string that is produced by the weight of the string. when you pluck the string slightly, the waves traveling up the string obey the equation: y(x, t) = (8.50 mm)cos(172 rad/m x − 4830 rad/s t)assume that the tension of the string is constant and equal to w. (a) how much time does it take a pulse to travel the fulllength of the string? (b) what is the weight w? (c) how many wavelengths are on the string at any instant of time? (d) what is the equation for waves traveling down the string?

Calculate the heat capacity per object when the total energy is 4 quanta. (think of this in terms of increasing from 3.5 quanta of energy in the system to 4.5 quanta of energy in the system, if that were possible.) c4 = __ j/k/object

Light that is polarized along the vertical direction is incident on a sheet of polarizing material. only 96% of the intensity of the light passes through the sheet and strikes a second sheet of polarizing material. no light passes through the second sheet. what angle does the transmission axis of the second sheet make with the vertical?
