In a given string, tension T is observed to equate to Kx, where x is the extension in the string due to tension. The speed of sound wave in a stretched string is v. If the extension in a string is increased to 1.5 x, then the speed of sound wave will be (Assume linear density does not change)

Answer the following : Explain the generation of sound in a loudspeaker with the help of neat diagram. Why should there be limit on the loudness of loudspeaker?

An 'app' may be available on cell-phones to measure the loudness of sound in decibel. With the help of your teacher, use the app to measure the sound level of a sound from a loudspeaker at some public place. Measure the sound level at different distances from the loudspeaker. Do you observe some relation between the distance from the loudspeaker and sound level?

Answer the following : How are different sound notes generated in musical instruments like guitar, which uses strings for sound generation, and flute, which uses blown air for sound generation?

A vibrating string of certain length l under a tension T resonates with a mode corresponding to the first overtone (third harmonic) of an air column of length 75cm inside a tube closed at one end. The string also generates 4 beats per second when excited along with a tuning fork of frequency n . Now when the tension of the string is slightly increased the number of beats reduces 2 per second. Assuming the velocity of sound in air to be 340 m//s , the frequency n of the tuning fork in Hz is

Consider a closed box of rigid walls so that the density of the air inside it is constant. On heating, the pressure of this enclosed air is increased from P_0 to P. It is now observed that sound travels 1.5 times faster than at pressure P_0 . Calculate P//P_0
