a) the moving car transfers kinetic energy to the parked car.

b) kinetic energy in the moving car disappears.

c) kinetic energy in the parked car is created.

d) the parked car transfers kinetic energy to the moving car.

Calculate the mass of an object that has a momentum of 100kg x m/sec and velocity of 4 m/sec

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?

The total amount of energy contained in an object
