Unpolarized light passes through two Polaroid sheets. The transmission axis of the second polarizing filter makes an angle of 480 with the axis of the first polarizer. What fraction of the original unpolarized light is transmitted through the second polarizing filter

Describe how the fermi level changes with donor level, temperature and contact with p and n type semiconductors

The difference between a red shift and a blue shift has to do with wavelength frequency. t or f

6–48 bananas are to be cooled from 24 to 138c at a rate of 215 kg/h by a refrigeration system. the power input to the refrigerator is 1.4 kw. determine the rate of cooling, in kj/ min, and the cop of the refrigerator. the specific heat of banana above freezing is 3.35 kj/kg·8c.
