The left end of a spring is attatched to a wall. WhenBob pulls on the right end with a 200 N force, he stretches thespring by 20 cm. The same spring is then used for a tug ofwar between Bob and Carlos. Each pulls on his end of thespring with 200 N force.

a) How far does Bob's wne of the spring move?

b) How far does Carlos end of the spring move?

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?

You charge a parallel-plate capacitor, remove it from the battery, and prevent the wires connected to the plates from touching each other. when you increase the plate separation, what happens to the following quantities?
