A wire 12.0 m long and having a mass of 90 g is stretched under a tension of 240 N. A pulse is sent from the left end of the string, and 20 ms later another pulse is sent in the opposite direction from the right end of the string. How far from the left end of the string do the pulses first meet

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?
