Please help. I need all steps, please do not use the delta dirac function as some other answers have for this question 4. (30 pts) A thick spherical shell (inner radius a, outer radius b) is made of dielectric material with a frozen-in polarization , where A is a constant, and r (x, y, z), r x2 +y2 + z2 is the vector and the distance from the center, respectively. (a) (10 pts) Calculate bound surface and volume charge densities...

Situation 1: You have a metal cube, measuring L on each side. The metal is in electrostatic equilibrium and has a net 4. charge of Q,. The cube has a cavity within it, however-where there is no metal. The shape of this cavity is not known. Somewhere within the cavity rests a point charge, q,. Its exact location is unknown, but it is not in contact with the inner wall of the cavity At a certain point P, on the...
1) Solve the problem. 1) The resale value of a certain industrial machine decreases over a 10-year period at a rate that changes with time. When the machine is x years old, the rate at which its value is changing is 280(x - 10) dollars per year. By how much does the machine depreciate during the fourth year? A) A decrease of $1540 B) A decrease of $1820 C) A decrease of $8960 D) A decrease of $1680 The slope...
Change of Variables When working integrals, it is wise to choose a coordinate system that fits the problem; e.g. polar coordinates are a good choice for integrating over disks. Once we choose a coordinate system we must figure out the area form (dA) for that system. For example, when switching from rectangular to polar coordinates we must change the form of the area element from drdy to rdrd0. To determine that rdrde is the correct formula how the edges of...
Problem 2 (9) Use kinetic theory of gasses to explain the following: a) As a glass of water evaporates, what happens to the temperature of the water? b) As a water vapor condenses onto a surface, what happens to the temperature of the vapor? c) As a solid sublimates, what happens to the temperature of the solid? Problem 3 [6] a) 15g of helium at 298K is equivalent to how many moles? molecules? volume? b) 15g of water at 298K...
Consider a cylindrical capacitor like that shown in Fig. 24.6. Let d = rb − ra be the spacing between the inner and outer conductors. (a) Let the radii of the two conductors be only slightly different, so that d << ra. Show that the result derived in Example 24.4 (Section 24.1) for the capacitance of a cylindrical capacitor then reduces to Eq. (24.2), the equation for the capacitance of a parallel-plate capacitor, with A being the surface area of...
