A steel tube of length 1.00 m is struck at one end. A person with his er close to the othr end hears the sound of the blow twice one travelign through the body of the tube and the other through the air in the tube. Find the time gap between the two hearings. Use the table in the next for speeds of sound in various substances.

A steel tube of length 1.00 m is struck at one end. A person with his ear close to the other end hears the sound of the blow twice one travelling through the body of the tube and the other through the air in the tube. Find the time gap between the two hearings.

A steel tube of length 1.00 m is struck at one end. A person with his ear close to the other end hears the sound of the blow twice one travelling through the body of the tube and the other through the air in the tube. Find the time gap between the two hearings.

A man strikes one end of a thin rod with a hammer. The speed of sound in the rod is 15 times the speed of sound in air. A woman, at the other end with her ear close to the rod, hears the sound of the blow twice with a 60 ms interval between, one sound comes through the rod and the other comes through the air alongside the rod. If the speed of sound in air is 343 m/s, what is the length of the rod?

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

Two persons stand near a railway line separated by a distance 2 km. A detonator is exploded by the first person. The second person 2 km away hears two sounds, one from the sound that has travelling through the rail and the other through the air. What is the interval between them? Given Young's modulus of steel = 2 xx 10^11 N//m^2. Density of steel = 8000 kg/m ""^3. Density of air = 1.29 kg/m ""^3. Atmospheric pressure =1 xx 10^(2) N//m^2. y for air = 1.4

If a person places his ear to one end of a long iron pipeline, he can distinctly hear two sounds when a workman hammers the other end of the pipeline. How ?

If the two tubes of lengths 50cm and 51cm closed at one end produce 7 beats in two second, when sounded to their fundamental notes neglecting end correction , then velocity of sound in air will be

A cylindrical metal tube has a length of 50 cm and is open at both ends. Find the frequencies between 1000 Hz and 2000 Hz at which the air column in the tube can resonate. Speed of sound in air is 340 m s^-1 .
