2. A 1.30-m long gas column that is open at one end and closed at the other end has a fundamental resonant frequency 80.0 Hz. What is the speed of sound in this gas?

To solve this problem, it will be necessary to apply the concepts related to the fundamental resonance frequency in a closed organ pipe.

This is mathematically given as

For fundamental frequency n is 0, then,

When,

v = Velocity of sound

L = Length,

Rearranging to find the velocity,

Therefore the speed of sound in this gas is 416m/s

answer: i don't know the answer good luck

explanation:

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.
