• In a sonometer wire, the tension is maintained by suspending a 50.7 kg mass from the free end of the wire. The suspended mass has a volume of $0.0075 m^3$. The fundamental frequency of the wire is 260 Hz. If the suspended mass is completely submerged in water, the fundamental frequency will become (take $g = 10 ms^{–2}$)

• A train moves towards a stationary observer with speed 34 m/s. The train sounds a whistle and its frequency registered by the observer is ${{f}_{1}}$. If the train’s speed is reduced to 17 m/s, the frequency registered is ${{f}_{2}}$. If the speed of sound is 340 m/s then the ratio ${{f}_{1}}/{{f}_{2}}$ is
