172759 The wavelength of two waves are 50 and $51 \mathrm{~cm}$ respectively. If the temperature of the room is $20^{\circ} \mathrm{C}$ then what will be the number of beats produced per second by these waves, when the speed of sound at $0^{\circ} \mathrm{C}$ is $332 \mathrm{~m} / \mathrm{s}$ ?

172760 10 forks are arranged in increasing order of frequency in such a way that any two nearest tuning forks produce 4 beats/sec. The highest frequency is twice of the lowest. Possible highest and the lowest frequencies (in $\mathrm{Hz}$ ) are

172762 A bus is moving with a velocity of $5 \mathrm{~ms}^{-1}$ towards a huge wall. The driver sounds horn of frequency $165 \mathrm{~Hz}$. If the speed of sound in air is $335 \mathrm{~ms}^{-1}$, the number of beats heard per second by the passengers in the bus will be

172763 The sound waves with wave lengths $5.0 \mathrm{~m}$ and $5.5 \mathrm{~m}$ respectively, each propagates in a gas with velocity $330 \mathrm{~m} / \mathrm{s}$. Number of beats that can be expected from them per sec is:
