Two fluids of densities p and 2p are layered in a cylindrical container of diameter d, as shown above. The height of each fluid is h, and the pressure at the top of the column is P0. What is the absolute pressure at the inside surface of the bottom of the container?

There are weak or strong attractive forces between atoms of liquids with a high viscosity

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.
