How does electricity turn into light in a common lightbulb? A. Electricity strikes the metal particles of the filament in a lightbulb. Some of the metal particles become gases and turn into light.

B. Electricity heats up the filament in the bulb to a very high temperature. At that temperature, the metal becomes bright and gives off light.

C. Electricity cools down the filament in the bulb to a very low temperature. At that temperature, the metal becomes bright and gives off light.

D. Electricity strikes the metal particles of the filament in a lightbulb. Some of the metal particles are ripped off from the metal and turn into light.

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?
