A flat circular coil 16 turns, each of diameter 20 cm, is in a uniform and steady 0.13-T magnetic field. a) Find the total magnetic flux through the coil when the field is perpendicular to the plane of the coil. A) 0.13 T middot m^2 B) 0.032 T middot m^2 C) 0.00032 T middot m^2 D) 0.065 T middot m^2 E) 0.00065 T middot m^2 If the coil is rotated in 10 ms so its plane is parallel to the field, find the average induced e in the coil. A) 6500 V B) 6.5 V C) 13000 V D) 13 V E) 3.2 V

James is trying to prove newton's 2nd law of motion. he tries to move four different objects with different masses, shapes, and sizes from point a to point b. the objects are a toy car, a car, a refrigerator, and a kitchen table. after some experimentation, he finds that force is dependent on the mass of the object, rather than it's size or shape. the object that takes the most force to move is the

There are two-speed cameras, one in an are where the speed limit is 30 km/h and another where the speed limit is 50 km/h. in which will there be a smaller time interval between the photographs? explain your answer.

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?
