172753 At a temperature of $27^{\circ} \mathrm{C}$, two identical organ pipes produce notes of frequency $140 \mathrm{~Hz}$. If the temperature of one pipe is raised to $57.75^{\circ} \mathrm{C}$, then the number of beats produced per second is

172755 Sound waves from a loudspeaker reach a point $P$ via two paths which differ in length by $1.8 \mathrm{~m}$. when the frequency of sound is gradually increased the resultant intensity at $P$ is found to be maximum when the frequency is $1000 \mathrm{~Hz}$. At what next higher frequency will a maximum be detected?
