A fan at a rock concert is 40.0 mm from the stage, and at this point the sound intensity level is 108 dBdB . Sound is detected when a sound wave causes the tympanic membrane (the eardrum) to vibrate . Typically, the diameter of this membrane is about 8.40 in humans?(A) How much energy is transferred to her eardrums each second ?
(B) How fast would a 2.00 mg mosquito have to fly to have this much kinetic energy?

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.
