Evaluate the following statements about an elephant and a feather falling through air reaching terminal velocity. select all that are true. the feather experiences more air resistance than the elephant and thus reaches a smaller terminal velocity. the feather experiences a smaller force of gravity acting on it so will need a smaller amount of air resistance to reach terminal velocity. both the elephant and the feather have the same acceleration due to gravity thus will reach the same terminal velocity. both elephant and feather have the same force of gravity acting on them, yet the feather experiences greater air resistance. after reaching terminal velocity both the elephant and the feather have zero acceleration and zero net force. both elephant and feather weigh the same amount, yet the greater mass of the feather leads to a smaller acceleration.

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?
