The gauge pressure in your car tires is 2.50×105n/m2 at a temperature of 35.0°c when you drive it onto a ship in los angeles to be sent to alaska. what is their gauge pressure on a night in alaska when their temperature has dropped to −40.0°c ? assume the tires have not gained or lost any air.

Unpolarized light of intensity i_0=750w/m^2 is incident upon two polarizers. after passing through both polarizers the intensity is i_2=280w/m^2. (a) what is the intensity of the light after it passes through the first polarizer in w/m^2? (b) write an equation for the angle between the polarizers in terms of the initial (i_0) and final (i_2) intensities. (c) find the angle between the polarizers in degrees.
