1. Sound with a speed of 345 m/s is sent down a 2.0 m long tube which is open at a both ends. a) What frequency of sound will produce the 4th harmonic? b) How many nodes will there be and where will they be in the tube?
2. The amplitude of the motion of a 200 gram mass on a spring is observed to halve in 2.00 minutes. Find the damping coefficient, b or the damping parameter B. At what time will the amplitude be the original amplitude?
3. Sound with a speed of 345 m/s is sent down a 2.0 m long tube which is open at a both ends. a) What frequency of sound will produce the 4th harmonic? b) How many nodes will there be and where will they be in the tube?
4. What length of tube closed at one end will produce the 5th harmonic with a frequency of 430 Hz? Assume the speed of sound is 345 m/s. What are the positions of the nodes and the antinodes?
