If a marathon runner averages 8.83 mi/h, how long does it take him or her to run a 26.22-mi marathon? express your answers in h, min and s.

Why there is no inductive reactance in dc circuits

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 are the three ways that an object can accelerate
