Acyclist moving with a constant velocity of 6.0 m/s forward passes a car that is just starting. if the car has a constant acceleration of 2.0 m/s2, when will the car overtake the cyclist?

Why there is no inductive reactance in dc circuits

Need only answer if you think you know it

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?
