Exam Name___________________________________ MULTIPLE CHOICE. Choose the one alternative that best completes the statement or answers the question. 1) 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 = 0.001 cos π (47 t - 17 x ). The amplitude of the wave, in SI units, is closest to: A) 0.001 x 17 π B) 0.001 π C) 0.001 D) 0.001 π /17 E) 0.001 x 17 1) 2) 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 = 0.006 cos π (46 t - 12 x ). The frequency of the wave, in SI units, is closest to: 2) 3) 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 = 0.005 cos π (38 t - 14 x ). The wave speed, including the sense of direction along the x - axis, in SI units, is closest to: 3) 4) 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 = 0.006 cos π (22 t - 16 x ). The propagation constant of the wave, in SI units, is closest to: 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 fixed 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 fixed end. In this situation, the propagation constant of the wave, in SI units, is closest to: 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 fixed 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 fixed end. In this situation, the tension in the string, in SI units, is closest to: 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 fixed 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 fixed end. In this situation, the maximum transverse velocity, of a point on the string, in SI units, is closest to: 8)
