I posted a physics question for 50 points, on my profile someone please help me
2+2*2+8=?

Which sound characteristic is not affected by the relative motion of an object

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?

Apersons beliefs and general outlook, which act like filters on the information they receive are called ?
