Acertain spring has a stiffness of 50 n/m. a block of mass 2 kg is attached to the end of the spring. find the damping coefficient b and damping rate γ if the systern is critically damped.

Aria drove to the store, did some shopping, and then came home. during maria's trip, when was her displacement equal to zero?

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?

Which of these metals are magnetic?
