Finally, the switch on the electromagnet is reopened. the magnitude of the external magnetic flux through the wire loop (a. increases, b. decreases, c. remains constant), and there is (a. zero, b. a clockwise, c. a counterclockwise) current induced in the loop (as seen from the left).

Write a question about how changing temperature affects the gas inside the sports ball

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?
