The valve is opened and air flows in until the process stops, and we assume the process is adiabatic. Find the final temperature and the air mass in the cylinder.

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?

Awave is produced in a rope. the wave has a speed of 33 m/s and a frequency of 22 hz.
