Determine whether the following are true or false: A) If Sis a surface parametrized byr:DR^3, then A(S) = (double integral)D dA, where A(S) is the surface area of S. B) Let c be a boundary of a closed and bounded region D in the xy-plane. Then counterclockwise is always a positive orientation of c. c) Let Fbe a constant vector field on R^3. Then the flux of F through the unit sphere x^2 + y^2 + 2^2 = 1 is...

PLEASE SHOW ALL WORK NEATLY! THANK YOU! (10 pts) Let F(x, y, z) = (x + y, y - 1, e), and let S be the part of the surface z = 9. 22 - y2 above the plane z=5, with downward orientation. Evaluate the flux of F across S by computing the surface integral IsF. ds.
NO.25 in 16.7 and NO.12 in 16.9 please. For the vector fied than the vecto and outgoing arrows. Her can use the formula for F to confirm t n rigtppors that the veciors that end near P, are shorter rs that start near p, İhus the net aow is outward near Pi, so div F(P) > 0 Pi is a source. Near Pa, on the other hand, the incoming arrows are longer than the e the net flow is inward,...
