(3) Consider the velocity field v -yi ( xy)j: Drag the circle around the plane, and change its radius in the following simulation: https://ggbm.at/bP7Evgpf. (a) Use the flux form of Greens theorem to explain why the flux out of any circle Centred at the line x = 0 is zero. (b) Use Greens theorem to explain why the circulation around any circle centred at the line y 0 is zero. (c) Explicitly calculate the circulation around a circle of unit radius centred at x- (d) Is v conservative?
