The graph indicates the running route for Tobias. A graph with horizontal axis time (seconds) and vertical axis position in (meters). The line runs in straight segments from 0 seconds 0 meters to 4 seconds 10 meters to 6 seconds 5 meters to 10 seconds 10 meters to 12 seconds 15 meters to 14 seconds 5 meters to 16 seconds 22 meters to to 20 seconds 28 meters. Which best describes his run?

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?
