A 'pop' gun consists of a tube 25 cm long closed at one end by a cork and at the other end by a tightly fitted piston. The piston is pushed slowly in. When the pressure rises to one and half times the atmospheric pressure, the cork is violently blown out. Calculate the frequency of the 'pop' caused by its ejection. Speed ofsound in air is 340 m/s

The pipe of a pop gun of length 15 cm is closed by a cork at one end a piston at the other end. When the pisotr is moved slowly and the pressure increase to 2.5 atm, the cork moves out with a pop sound. Calculate the frequency of the pop sound. The velocity of sound in air = 384 m//s

A pop- gun consists of a cylindrical barrel 3cm^(2) in cross section closed at one end by a cork and having a well fitting piston at the other. If the piston is pushed slowly, in the cork is finally ejected, giving a pop, the frequency of which is found to be 512Hz . Assuming that the initial distance between the cork and the piston was 25cm and that there is no leaking of air, calculate the force required to eject the cork. Atmospheric pressure =1kg.cm^(2) , v=340m//s (in kg. wt).

Two pipes have equal length of 2m, one is closed at one end and the other is open at both ends. The speed of sound in air is 340m//s . At what frequency will both the pipes resonate ?

two pipes have each of length 2 m, one is closed at on end and the other is open at both ends. The speed of sound in air is 340 m/s . The frequency at which both can resonate is ?

An adibatic cylindrical tube of cross-sectional area 1 cm^(2) is closed at one end fitted with a piston at the other end. The tube contains 0.03 g of an ideal gas . At 1 atm pressure and at the temperture of the surrounding, the length of the gas column. The pressure of the gas falls to 0.355 atm . Find th speed of sound in the gas at atmospheric temperture.

A pipe 17 cm long is closed at one end. Which harmonic mode of the pipe resonates a 1.5 kHz source? (Speed of sound in air = 340 m s^(-1) )

A string 25cm long and having a mass of 2.5 gm is under tension. A pipe closed at one end is 40cm long. When the string is set vibrating in its first overtone and the air in the pipe in its fundamental frequency, 8 beats per second are heard. It is observed that decreasing the tension in the string decreases beat frequency. if the speed of sound in air is 320m//s , find the tension in the string.

A string 25 cm long fixed at both endds and having a mass of 2.5 g is under tension. A pipe closed from one end is 40 cm long. When the strin is set vibrating in its first overtone and the air in the pipe in its fundamental frequency, 8 beats per second are heard. If is observed that decreasing the tension in the string decreases the beat frequency. If the speed of sound in air is 320 m//s . Find tension in the string.
