Divergence and flux from graphs Consider the following vector fields, the circle C, and two points P and Q. a. Without computing the divergence, does the graph suggest that the divergence is positive or negative at P and Q? Justify your answer. b. Compute the divergence and confirm your conjecture in part (a). c. On what part of C is the flux outward? Inward? d. Is the net outward flux across C positive or negative? 22. F = ( x, y 2 )

Quantities that have magnitude and direction but not position. Some examples of vectors are velocity, displacement, acceleration, and force. They are sometimes called Euclidean or spatial vectors.
