Scenario
A group of students has been testing electromagnets in the lab. They made an electromagnet by
wrapping copper wire around a nail. For one set of tests, they wrapped the wire around the nail 25 times.
For the second set of tests, they wrapped the wire around the nail 50 times. They also have 4 different
batteries: 1.5 V, 3.0 V, 4.5 V, and 6.0 V. They use their electromagnets to see how many paper clips each
can pick up.
Data
For each electromagnet, two trials were conducted at each voltage. The data was recorded in the tables
below.

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?
