Sketch and describe the vector field F (x, y) = (-y,2x)

Using a graphic calculator, plot the vector field F(x, y) = j. Explain briefly with words why the plot x²+y? has this shape.

Please solve and explain this multi variable calculus problem. Thank you.

only solute question c ， please

Horizontal cross-sections of the vector fields F⃗ (x,y,z) and G⃗ (x,y,z) are given in the figure. Each vector field has zero z-component (i.e., all of its vectors are horizontal) and is independent of z (i.e., is the same in every horizontal plane). You may assume that the graphs of these vector fields use the same scale. (a) Are div(F⃗ ) and div(G⃗ ) positive, negative, or zero at the origin? Be sure you can explain your answer. At the origin, div(F⃗ ) is At the origin, div(G⃗ ) is (b) Are F⃗ and G⃗ curl free (irrotational) or not at the origin? Be sure you can explain your answer. At the origin, F⃗ is At the origin, G⃗ is (c) Is there a closed surface around the origin such that F⃗ has nonzero flux through it? Be sure you can explain your answer by finding an example or a counterexample. (d) Is there a closed surface around the origin such that G⃗ has nonzero circulation around it? Be sure you can explain your answer by finding an example or a…
