A metal ring 5.00 cmcm 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 TT between them but are gradually pulled apart, causing this field to remain uniform but decrease steadily at 0.210 T/sT/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?

You are about to open a container of soy milk but notice that there are instructions to “shake well before serving.” the soy milk is most likely a

A250-n box is at rest on a frictionless horizotal floor. then a person shoves the box with a non-zero force of magnitude p. which statement best describes the relationship betweeen p and the motion of the box after it was shoved? -the box will not move when p< 250n but otherwise will accelerate at a constant rate that is directly proportional to p - the box will begin moving at a speed that is directly proportional to p, then will gradually slow to a halt -the box will move with constant velocity at a speed that is directly proportional to p -box will accelerate across the floor at a constant rate that is directly proportional to p

The bar of prob. 5/82 is repeated here. the ends of the 0.4-m bar remain in contact with their re- spective support surfaces. end b has a velocity of 0.5 m/s and an acceleration of 0.3 m/s2 in the di- rections shown. determine the angular accelera- tion of the bar and the acceleration of end a.
