Alinearly polarized electromagnetic wave has an average intensity of 196 w/m^2. this wave is directed towards two ideal polarizers (in real polarizers, transmission is also effected by reflection and absorption). polarizer a is oriented with its transmission axis at an angle of θ_1=20.8â with the incident electric field. polarizer b has its axis at an angle of θ_2=63.0â with the incident electric field. what is the average intensity of the wave after it passes through polarizer a? what is the average intensity of the wave after it passes through polarizer b? suppose that the two polarizers a and b are interchanged. what would the average intensity be after passing through both polarizers?

An insulated thermos contains 148 g of water at 72.7 Ëc. you put in a 11.7 g ice cube at 0.00 Ëc to form a system of ice + original water. the specific heat of liquid water is 4190 j/kgâ˘k; and the heat of fusion of water is 333 kj/kg. what is the net entropy change of the system from then until the system reaches the final (equilibrium) temperature?
