Why would replacing the air inside a metal organ pipe with helium gas raise the pipe’s pitch?
Q: a. Helium lowers the total mass of the organ pipe so that metal pipe can vibrate more rapidly.
b. Helium has a lower pressure than air, so it allows the metal pipe to vibrate more rapidly.
c. Helium is less dense than air, so it accelerates more rapidly than air.
d. Helium has a lower pressure than air, so it accelerates more rapidly than air.
A: I agree, C, the speed of sound in a gas increases as density decreases.
