While on the alien planet you come across what appears to be an infinite solid cylinder of radius r. it has a linear charge density of λ. the volume charge density inside the cylinder is rho(r) rpo/r, where po is a constant. a) the charge within a small volume dv is dq pdv. the integral of pdv over a cylinder of length l is the total charge q-al within the cylinder. using this, prove that rho,-32/2πr2. b) use gauss's law to find an equation for the e-field inside the cylinder. c) what is the value of e when r-r using part b. is it what you expect it to be?

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?

Acommercial refrigerator with refrigerant-134a as the working fluid is used to keep the refrigerated space at -35°c by rejecting waste heat to cooling water that enters the condenser at 18°c at a rate of 0.25 kg/s and leaves at 26°c. the refrigerant enters the condenser at 1.2 mpa and 50°c. if the compressor consumes 3.3 kw of power, determine (a) the mass flow rate of the refrigerant, (b) the refrigeration load, (c) the cop, and (d) the minimum power input to the compressor for the same refrigeration load.
