Neco Model Questions Vol1 2025 Physics Question 43
Practice objective / multiple choice question 43 from the 2025 Neco Model Questions Vol1 Physics examination.
Two tuning forks produce tones of frequencies \(500\ \text{Hz}\) and \(495\ \text{Hz}\). The \(500\ \text{Hz}\) fork is mounted on a cart that moves directly towards a stationary observer at a speed of \(10\ \text{m s}^{-1}\) in air at \(20^{\circ}\text{C}\). The speed of sound in air is given by \(v = 331 + 0.6T\) (m s\(^{-1}\)). What beat frequency does the observer hear? Give your answer in hertz, rounded to the nearest whole number.
