Gce Model Questions Vol1 2019 Physics Question 7
Practice objective / multiple choice question 7 from the 2019 Gce Model Questions Vol1 Physics examination.
A pipe open at both ends has length \(0.60\ \text{m}\). At an initial temperature \(T_{1}\) the fundamental frequency observed is \(340\ \text{Hz}\). After heating, the pipe resonates at its first overtone (second harmonic) with a measured frequency of \(720\ \text{Hz}\). The speed of sound in air varies with temperature as \(v = 331 + 0.6\,T\) (with \(v\) in \(\text{m s}^{-1}\) and \(T\) in \(^\circ\text{C}\)). Calculate the temperature increase \(\Delta T = T_{2} - T_{1}\) in degrees Celsius.
