A pipe of length 1.5m closed at one end is filled with a gas and it resonates in its fundamental with a tuning fork. Another pipe of the same length bur open at both ends is filled with air and it also resonates in its fundamental with the same tuning fork. Calculate the velocity of sound at 0^(@)C in the gas. Given that the velocity of sound in air is 360 m/s at 30^(@)C where the experiment is performed.

A column of air at 51^(@)C and a tuning fork produce 4 beats per sec when sounded together. As the temperature of the air column is decreased, the number of beats per sec tends to decrease and when the temperature is 16^(@)C the two produce 1 beat per see. Find the frequency of the tuning fork.
