Q6. Gauss Law (20 points) As shown in the following figure, a solid insulating spherical shell of inner radius $R_4$ and outer radius $R_3$ carries a net charge $Q_1$ uniformly distributed throughout its volume. A conducting spherical shell of inner radius $R_2$ and outer radius $R_1$ is concentric with the solid insulating spherical shell and carries a net charge $Q_2$. Using Gauss's Law, find the electric field in regions labeled (1), (2), (3), (4), and (5) in the figure and the charge distribution on the conducting spherical shell when the entire system is in electrostatic equilibrium.

Watch the movie (it is located in the folder Movie inside the module in Canvas for the Final Exam) or even better you can watch it in Showtime if you are a subscriber to the service. Also watch the scene from the series The Sopranos that happens in a Boiler room and read the article from the Detroit Free Press and answer the following questions: 1) What is called a boiler room? 2) In the movie, it is explained how the owner of the brokerage firm makes money, try to explain it in your own words 3) Why does the operation is illegal? 4) In a boiler room operation who are the typical persons who lose money? (describe their typical profile and why they are chosen as preys by the scam men)

A block slides UP a ramp which is inclined at an angle 7°. The block has speed 7 m/s at the bottom of the ramp. How far does the block slide along the ramp before coming to a stop if the coefficient of kinetic friction between the block and the ramp is 0.7? Note there are different versions of this problem. Read carefully.

A new supercar has been launched by the Proton Company and the velocity can be expressed in the following function: v(t) = 15t^3 + 30t^2 + 10t where the unit velocity is measured in m/s and t in seconds. Determine the acceleration of the supercar at t = 3 by using: (i) 3-point central difference (ii) 5-point central difference Use h = 0.0001. (b) The rate of heat flow (conduction) between two points on a cylinder heated at one end is given by dQ = 1AdT/dx, where dQ is the heat flow, A is the cylinder's cross-sectional area, T is the temperature, t is the time, and x is the distance from the heated end. Given that dT/dx = (100(L-x)(20-t))/(100-xt), where L is the length of the rod. If the initial condition is Q(0) = 0 and the parameters are A = 10 cm, L = 20 cm, x = 2.5 cm, and d = 0.4 cal/cm/s, compute the heat flow for t = 0 to 25 s by using the Midpoint method. Use h = 5.

Problem 2: (a) Show that $f(x)\frac{d}{dx}\delta(x) = f(0)\frac{d}{dx}\delta(x) - f'(0)\delta(x)$ (1) (b) Write a general expression (it may include derivatives that are not evaluated) for the fourier transform of $f(x) = x^{2n}e^{-x^2/2}$ (2) where $n$ is a positive integer. (hint: it is useful to use $e^{-x^2/2}$ to define the expression). Evaluate your expression for $n = 1, 2, 3$. (c)Determine the fourier transform of $h(x) = \int^x dx'h(x')$ (3) in terms of the fourier transform of $h(x)$, $\tilde{h}(k)$, and $k$. (d) Determine an analytic expression the fourier transform of $f(x) = |x|^\alpha e^{-|x|} $ (4) as a function of $\alpha$ (You can use Mathematica). Compute the series around $\alpha = -1$ and $\alpha = -2$. Explain what happens to the fourier transform at these points in terms of the behavior of the integral that defines the transform.
