Neco Model Questions Vol1 2020 Physics Question 19
Practice objective / multiple choice question 19 from the 2020 Neco Model Questions Vol1 Physics examination.
A stationary source emits sound of frequency \(f = 500\ \text{Hz}\) in air where the speed of sound is \(v = 340\ \text{m s}^{-1}\). A second identical source moves directly towards a stationary observer with speed \(v_s\). The observer hears a beat frequency of \(5\ \text{Hz}\) between the two sounds. Determine the speed \(v_s\) of the moving source (in m s\(^{-1}\), to two decimal places).
