Find the net flux of the vector field F($aya Z) : ($1913) over the open surface 5 given by the upper part (only) of the intersection of the graph of the function z=f(m,y) = Its$2 y2 with the plane 2: = 7. In other words, evaluate the surface integral in a vector field [LP-d8, where the normal n is the outer normal to S (that is, pointing upwards} and S is the open surface described above
