The propagation constant of the wave, in SI units, is closest to: A) 8.0 B) 50 C) 32 D) 16 E) 22 4) 5) A transverse wave is propagated in a string stretched along the x - axis. The equation of the wave, in SI units, is given by: y = 0.002 cos π (52 t - 15 x ). The maximum velocity of a particle on the string, in SI units, is closest to: A) 0.64 B) 0.53 C) 0.43 D) 0.33 E) 0.74 5) 6) A string, 90 cm long and having a mass of 93 g, is attached to a 730 - Hz vibrator at one end. The other end of the string is Fxed and the string is kept under tension. The vibrator produces a transverse wave in the string, whose amplitude is 3.0 mm, and that propagates with a velocity of 76 m/s. The energy of the wave is absorbed at the Fxed end. In this situation, the propagation constant of the wave, in SI units, is closest to: A) 9.6 B) 48 C) 19 D) 60 E) 30 6) 7) A string, 80 cm long and having a mass of 61 g, is attached to a 660 - Hz vibrator at one end. The other end of the string is Fxed and the string is kept under tension. The vibrator produces a transverse wave in the string, whose amplitude is 5.0 mm, and that propagates with a velocity of 32 m/s. The energy of the wave is absorbed at the Fxed end. In this situation, the tension in the string, in SI units, is closest to: A) 87 B) 78 C) 75 D) 84 E) 81 7) 1

8) A string, 30 cm long and having a mass of 14 g, is attached to a 750 - Hz vibrator at one end. The other end of the string is Fxed and the string is kept under tension. The vibrator produces a transverse wave in the string, whose amplitude is 8.0 mm, and that propagates with a velocity of 54 m/s. The energy of the wave is absorbed at the Fxed end. In this situation, the maximum transverse velocity, of a point on the string, in SI units, is closest to: A) 40 B) 35 C) 42 D) 38 E) 33 8) 9) A string, 50 cm long and having a mass of 57 g, is attached to a 910 - Hz vibrator at one end. The other end of the string is Fxed and the string is kept under tension. The vibrator produces a transverse wave in the string, whose amplitude is 6.0 mm, and that propagates with a velocity of 25 m/s. The energy of the wave is absorbed at the Fxed end. In this situation, the average
