An electric power plant manages to transfer 76% of the heat produced in the burning of fossil fuels to steam. of the heat carried by the steam, 45 % is converted to mechanical work of the spinning turbine. which best describes the overall efficiency of the heat-to-work conversion of the plant? greater than 76% efficient 76% efficient 45% efficient less than 45% efficient

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=20.8∘ with the incident electric field. polarizer b has its axis at an angle of θ_2=63.0∘ 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?
