Q. If an astronaut jogged in the direction of the rotation at 6.10 m/s, what simulated gravitational acceleration would the astronaut feel?

Q. What are the first, second, and third frequencies audible from a 20cm long organ pipe when (1) only one end is open and when (2) both ends are open. The speed of sound through the air inside the organ pipe is 343 m/s. (Hint: if a harmonic does not exist, it would not be heard.)
