Neco 2022 Physics Question 2
Practice objective / multiple choice question 2 from the 2022 Neco Physics examination.
An acoustic source emits a tone of frequency \(f = 500\) Hz in air where the speed of sound is \(v = 340\) m s(^{-1}). The source moves directly towards a stationary observer with speed \(v_s = 30\) m s(^{-1}). At the same time the observer moves directly away from the source with speed \(v_o = 20\) m s(^{-1}). Determine the frequency heard by the observer. Give your answer to the nearest hertz.
