Question
The figure in this exercise shows a horizontal layer of the vector field of a fluid flow in which the flow is parallel to the xy-plane at every
point and is identical in each layer (i.e., is independent of z). State whether you believe that the curl is nonzero at the origin. If you
believe that it is nonzero, then state whether it points in the positive or negative z-direction.
X
O The curl at the origin is zero.
O The curl at the origin is nonzero and points in the negative z-direction.
O The curl at the origin is nonzero and points in the positive z-direction.
