Calculate the energy of a photon of wavelength 11.56 meters. (planck’s constant is 6.626 x 10-34 joule seconds; the speed of light is 2.998 x 108 m/s)
5.32 x 1042 joules
2.555 x 10-41 joules second
1.718 x 10-26 joules
7.659 x 10-35 joules
1.9864 x 10-26 joules/second

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.

It is reasonable to assume that the bulk modulus of blood is about the same as that of water (2.2 gpa). as one goes deeper and deeper in the ocean, the pressure increases by 10000 pa for every meter below the surface. if a diver goes down 80.0 m in the ocean, by how much does each cubic centimeter of her blood change in volume? give the answer in cubic centimeters (actually one cubic centimeter equals one milliliter).
