A source moves towards a stationary observer with a speed of 20m/s. If the frequency of the source is 100Hz and speed of sound is 330m/s, determine the apparent frequency heard by observer(ii) Determine the wavelength of sound heard by the observer in part a.108.5Hz;  3.55mb.108.5Hz; 2:10 mc.104.5Hz; 3.10 md.96.45Hz; 3.55me.106.45Hz; 3.10mf.104.5Hz; 3.67 m

The frequency of a tuning fork is 300 Hz. If the velocity of sound is 324 m/s; find the distance between a compression and the next rarefaction.Select an answerA5.14 cmB10.8 cmC54 cmD108 cm

A 1024 Hz tuning fork is dangled at the end of a string such that its center of mass is 1.2 m below the point at which the other end of the string is attached to door frame, making a pendulum of sorts. The tuning fork may be treated as a point mass for the purposes of this problem. If the pendulum is brought to an amplitude of 22o and released, what is the range of frequencies heard by an observer standing in the plane of the pendulum's motion? The speed of sound is 340 m/s.

Frequency of a wave travelling from source to receiver is 200 Hz. If the speed of sound wave is 100 m/s.Time period of wave is;

A resonance occurs with a tuning fork and air column of size 12cm. the next higher resonance occurs with an air column of 38cm. What is the frequency of the tuning fork? Assume that the speed of sound is 312m/s
