- SSF. = SSST. F Find the outward flux of the vector field F = (z,y,z the boundary of the cylinder x² + y² = 4, and includes its bottom the surface S. S is + y) through and top given by z = 0 and z = 8.arrow_forwardSolvearrow_forwardThe magnetic field B due to a small current loop (which we place at the origin) is called a magnetic dipole (Figure). Let p = (x² + y² + z²)2. For p large, B = curl(A), where y A = . p3 > Let C be a horizontal circle of radius R = 5 with center (0, 0, 10). Use Stokes' Theorem to calculate the flux of B through C.

- 1. Let R and b be positive constants. The vector function r(t) = (R cost, R sint, bt) traces out a helix that goes up and down the z-axis. a) Find the arclength function s(t) that gives the length of the helix from t = 0 to any other t. b) Reparametrize the helix so that it has a derivative whose magnitude is always equal to 1. c) Set R = b = 1. Compute T, Ñ, and B for the helix at the point (√2/2,√2/2, π/4).arrow_forwardNeed help with part (e). Thank you :)arrow_forwardHeat transfer Fourier’s Law of heat transfer (or heat conduction) states that the heat flow vector F at a point is proportional to the negative gradient of the temperature; that is, F = -k∇T, which means that heat energy flows from hot regions to cold regions. The constant k > 0 is called the conductivity, which has metric units of J/(m-s-K). A temperature function for a region D is given. Find the net outward heat flux ∫∫S F ⋅ n dS = -k∫∫S ∇T ⋅ n dS across the boundary S of D. In some cases, it may be easier to use the Divergence Theorem and evaluate a triple integral. Assume k = 1.
