The speed of sound in fresh water at 293 K is 1482 m/s. At what temperature is the speed of sound in helium gas the same as that of fresh water at 293 K? Helium is considered a monatomic ideal gas ( y = 167 and atomic mass = 4.003 u). 0 442K 0 633K 0 377K 0 525K 0 313K Awave moves at a constant speed along a string. Which one of the following statements is false concerning the motion of particles in the string? 0 The particle speed is constant. 0 The particle speed is independent of the tension and linear density of the string. 0 The particle speed depends on the frequency of the periodic motion of the source. 0 The particle speed depends on the amplitude of the periodic motion of the source. 0 The particle speed is not the same as the wave speed. A wave is traveling at 35 m/s on a string with a linear density of 0.0082 kg/m. What is the tension in the string? 0 5.0 N O 10.N O 0.56 N O 2.5 N O 0.28 N
