Two identical pipes, one at the front and one at the back, havefundamental frequencies of 334.0 Hz at 20.0°C. During a performance, the organ pipes at the back of the hall are at 26.4°C, whilethose at the front are still at 20.0°C. What is the beat frequency when the two pipes sound simultaneously?HzeBookHint12A geological survey ship mapping the floor of the ocean sends sound pulses down from the surface and measures the time taken forthe echo to return. How deep is the ocean at a point where the echo time (down and back) is 5.80 s? The temperature of the seawateris 25.0°C. Speed of the sound in seawater is 1533 m/s (see table 12.1)HintRequired informationA ship mapping the depth of the ocean emits a sound of 49.4 kHz. The sound travels to the ocean floor and returns 0.870s later. The speed of sound in sea water is about 1533 m/s (see table 12.1).How deep is the water at that location?mkmRequired informationAn aluminum rod, 1.00 m long, is held lightly in the middle. One end is struck head-on with a rubber mallet so that alongitudinal pulse-a sound wave-travels down the rod. The fundamental frequency of the longitudinal vibration is 2.00kHz.Calculate the speed of sound in aluminum from the information given in the problem.km/sRequired informationAkiko rides her bike toward a brick wall with a speed of 7.00 m/s while blowing a whistle that is emitting sound with afrequency of 488.0 Hz. Speed of sound in air at 20.0°C is 343 m/s.What is the frequency of the sound that is reflected from the wall as heard by Haruki, who is standing still?Hz
