Focus in on paragraph four to answer this question. The paragraph in Revere’s letter about his visit to Lexington “the Sunday before” seems out of place at first. Yet, from this paragraph, you can infer something very important related to Paul Revere’s ride. What is it?

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?
