For the flow field given in cartesian coordinates by u = 2y 3y2z 3ar, w=0: (a) is the flow steady? (b) is the flow compressible or incompressible? (c) if viscous and gravitational forces are negligible, find the pressure gradient

Ametal ring 4.20 cm in diameter is placed between the north and south poles of large magnets with the plane of its area perpendicular to the magnetic field. these magnets produce an initial uniform field of 1.12 t between them but are gradually pulled apart, causing this field to remain uniform but decrease steadily at 0.240 t/s . (a) what is the magnitude of the electric field induced in the ring? (b) in which direction (clockwise or counterclockwise) does the current flow as viewed by someone on the south pole of the magnet?
