Instruments in airplane a indicate that, with respect to the air, the plane is headed 30° north of east with an air speed of 480.00 mi/h. at the same time, radar on ship b indicates that the relative velocity of the plane with respect to the ship is 370.00 mi/h in the direction 33° north of east. given, the ship is steaming due south at 12 mi/h.

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?
