Question

1-In simple harmonic motion the magnitude of the acceleration is greatest when the? (ANS: Velocity is Zero) Explain 2- two pure tones are sounded together and a particular beat frequency is heard. What happens to the beat frequency if the frequency of one of the tones is increased? (ANS: it could be either increase or decrease) Explain 3- The C note on a flute and a clarinet have the same pitch, but the two are clearly distinguishable. Which property is most important in enabling to distinguish between these two instruments? (ANS: Fundamental Frequency) Explain

Explanation / Answer

1.

in simple harmonic motion displacement is given as

X = A Sinwt

velocity is given as

V = (Aw) Coswt

and acceleration is given as

a = - Aw2 Sinwt

acceleration is greatest when Sinwt = 1 or wt = 90

when wt = 90 , velocity is given as

V = (Aw) Coswt =  (Aw) Cos90 = 0 m/s
