At the beginning of a unit on forces, Ms. Alton is leading a class discussion asking her students what they know about forces. Below is a list of the ideas brought up by her class.

I. A force is a push or pull on an object.
II. The amount of force an object has depends on its size.
III. Forces have both a strength and direction.
IV. When two objects collide, the force of one object is transferred to the second object.
V. A moving object stops when its force is used up.
VI. There are no forces on an object that is not moving.
Which of these student responses would you consider to be correct?
For each that is incorrect, what is incorrect about it?

Electromagnetic induction. a coil of wire contains n turns and has an electrical resistance r. the radius of each turn is a. initially, inside the coil there exists a uniform magnetic field of magnitude b0 parallel to the axis of the coil. the magnetic field is then reduced slowly. the current induced in the coil is i. how long does it take for the magnitude of the uniform field to drop to zero?

During the experiment if you could triple the breakaway magnetic force with all other quantities left unchanged, what is the new value for the critical velocity if it was v0 (initial velocity), initially? (b) now if you halved the radius with all other quantities left unchanged, what is the new critical velocity if it was v0 (initial velocity), initially? (c) if during the experiment, critical velocity quadrupled with all other quantities left unchanged, what is the new breakaway force if its magnitude was initially f0,?
