A solid conducting sphere of radius a is surrounded by a layer of linear dielectric between a < r < b . The linear dielectric has a non-uniform dielectric constant. A grounded very thin conducting shell coats the outer surface of the linear dielectric at radius b. Find the displacement field D in the region a < r < b.

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.

Consider an insulating crystal, made up of layers of atoms. what form would you expect the temperature dependence of the phonon heat capacity to approach at extremely low temperatures if the interlayer coupling is i)very strong (rigid coupling), and ii) very weak. explain.
