Magnetic flux density is given as B =* = 6+ Problem [1] <15 points> on a surface given by r = 510,= = 48. Calculate the total flux o passing through this surface. For Problems 2 to 4: Figure shows a resistive loop with resistance of 2 Ohms. Magnetic flux density in this region is B = (2zł + 3xý)e ^.

(8). The one dimensional neutron diffusion equation with a (plane) source at x-0 is d'f(x) n (2) +002 f (x)-00(x) dx where f(x) is the flux of neutrons (f(x)→0 as x→±o), Q δ (x) is the (plane) source at x-0 (5(x) is the Dirac delta function), and o is a constant. This problem involves finding the solution to this equation using Fourier Transforms. You may use the formulas derived in class for the Fourier Transform of derivatives, but otherwise compute...

4. PROBLEM A planar source at the center of an infinite slab of graphite 2 meters thick emits 108 thermal neutrons per cm/sec. Given that the same system is at room temperature, calculate a) total number of thermal neutrons b) number of thermal neutrons absorbed per cm2/sec of the slab c) neutron current as function of position in the slab. d) Total number of neutrons leaking per cm2/sec from the two surfaces of the slab; e) probability that a source...

(1 point) This problem will illustrate the divergence theorem by computing the outward flux of the vector field F(x, y, z) - 2ri + 5y + 3-k across the boundary of the right rectangular prism: -3 <<6, -15y<3,-425 oriented outwards using a surface integral and a triple integral over the solid bounded by rectangular prism. Note: The vectors in this field point outwards from the origin, so we would expect the flux across each face of the prism to be...

For Problems 5 to 6: Figure shows a capacitor connected to a voltage source. There are two dielectric slabs stacked in the capacitor. The dielectric slabs are not perfect dielectrics, thus they have finite conductivities. Hint: Notice that electric flux densities in dielectrics 1 and 2 are equal: D -D Another hint: You can imagine this structure as two capacitors connected in series. Can you find the voltage V1 on capacitor 1. d. Problem [5] <15 points> Calculate the magnitude...
