Most rivers curve or meander. water travels more slowly on the outside of the curve and more quickly on the inside of the curve. which statement is true?
the pressure on the inside of the curve of a river channel is greater than the pressure on the outside.
all the water is part of the river, so the pressure is the same throughout.
the pressure on the inside of the curve of a river channel is less than the pressure on the outside.
the pressure is greatest in the middle of the river channel.

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?
