Two parallel conducting wires are connected by a light bulb (represented by a resistor). A non ferrous bar is placed across the two wires. The entire setup is placed in a uniform magnetic field. On paper, the wires are drawn horizontally and the magnetic field is out of the page. Initially bar is pulled to the right at a constant speed. Which direction is the current through the circuit formed by the resistor, wires, and bar?a. There no current. b. clockwise c. Counter clockwise.

Arotating space station is said to create “artificial gravity”—a loosely-defined term used for an acceleration that would be crudely similar to gravity. the outer wall of the rotating space station would become a floor for the astronauts, and centripetal acceleration supplied by the floor would allow astronauts to exercise and maintain muscle and bone strength more naturally than in non-rotating space environments. if the space station is 200 m in diameter, what angular velocity would produce an “artificial gravity” of 9.80 m/s^{2} 2 at the rim?

What is the final velocity of the initial velocity of 25 and -50?
