Find the work done in pumping gasoline that weighs 6600 newtons per cubic meter. a cylindrical gasoline tank 3 meters in diameter and 2 meters long is carried on the back of a truck and is used to fuel tractors. the axis of the tank is horizontal. the opening on the tractor tank is 5 meters above the top of the tank in the truck. find the work done in pumping the entire contents of the fuel tank into the tractor.

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?
