Two parallel rods are each 0.39 m in length. They are attached at their centers to a spring that is initially neither stretched nor compressed. The spring has a spring constant of 220 N/m. When 1200 A of current is in each rod in the same direction, the spring is observed to be compressed by 2.7 cm. Treat the rods as long, straight wires and find the separation between them when the current is present. Number i Units The x,...

The drawing below shows a copper wire moving vertically upward at a constant velocity in a magnetic field that is perpendicular to the velocity and directed toward you. Which one of the following statements concerning an induced emf in the wire is true? B An emf will be induced in the wire such that both ends of the wire will have a net negative charge. An emf will be induced in the wire such that the left end of the...
The drawing shows two identical systems of objects; each consistsof the same three small balls connected by massless rods. In bothsystems the axis is perpendicular to the page, but it is located ata different place, as shown. The same force ofmagnitude F is applied to the same ball in eachsystem (see the drawing). The masses of the ballsare m1 = 8.4 kg, m2 = 5.2 kg,and m3 = 5.0 kg. The magnitude of the forceis F = 446 N. (a)...
