Neco Model Questions Vol1 2023 Physics Question 40
Practice objective / multiple choice question 40 from the 2023 Neco Model Questions Vol1 Physics examination.
A cylindrical pipe closed at one end has an effective length of \(0.85\ \text{m}\). The air inside the pipe is at a temperature of \(27^{\circ}\text{C}\). (i) Calculate the speed of sound in the air at this temperature using \(v = 331 + 0.6T\) (with \(v\) in \(\text{m s}^{-1}\) and \(T\) in \(^\circ\text{C}\)). (ii) Determine the fundamental frequency of the pipe (closed at one end). (iii) If a tuning fork of frequency \(440\ \text{Hz}\) is sounded nearby, what beat frequency will be heard? Give all answers to three significant figures.
