Neco 2025 Physics Question 44
Practice objective / multiple choice question 44 from the 2025 Neco Physics examination.
A source emits sound of frequency \(f=800\) Hz. An observer moves toward the source at \(v_{o}=10\) m s\(^{-1}\) while the source moves away from the observer at \(v_{s}=5\) m s\(^{-1}\). The speed of sound in air is \(v=340\) m s\(^{-1}\).\n\n(a) Determine the frequency heard by the observer.\n(b) The observer also hears a second stationary source emitting \(795\) Hz. Calculate the beat frequency between the two sounds heard.
