Find the ux of the field F(x,y,z) = 22 i + X] 62 k outward through the surface cut from the parabolic cylinder 2 = 1 y2 by the planes x = O, x = 1, and z = O. The flux is . (Simplify your answer.) Use a parametrization to find the flux F . n do of F = 5zk across the portion of the sphere x2 + y + z = a where z is positive in the direction away from the origin. S . . . The flux is . (Type an exact answer in terms of It.)
