Plz answer each of them thanks so much

Conservative Vector Fields 7 Determine whether the following vector fields are conservative. If they are , find a potential function. a) F = Ost= 4 Green's Thecrem, divergence d carl 9 For each of the following vector fields Fland reglove ? ( i) compute the two dimensional divergence and Curl ( i) Evaluate both integrals in the circulation form of Green's Theorem ( 1:) Evaluate both integrals in the flux form of Green's Theorem ( iv ) Is the vector field conservative , sauce free , or neither? 1) F .
