A city bus travels 6 blocks East and 8 blocks north. Each block is 100 meters long. If the bus travels this distance in 15 minutes, what isn’t the average speed of the bus (m/s)? Using info from the answer to that what also is the velocity of the city bus?

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?
