PHYS 2C, W 2006 QUIZ #5 Version A Name___________________________________ Code______________ MULTIPLE CHOICE. Choose the one alternative that best completes the statement or answers the question 1) A 170.0 - MHz electromagnetic wave propagates through a cable. If the wavelength of this signal is 0.97 m, what is the speed of the waves in the cable? Express your answer in terms of the speed of light, c = 3.00 x 10 8 m/s. A) 0.550 c B) 0.330 c C) 0.407 c D) 0.479 c 1) 2) A simple harmonic wave of amplitude 9.91 m, wave number 2.34 m - 1 , and angular frequency 2.88 rad/s, is propagating in the + x direction. At time t = 0 the displacement caused by the wave at point x = 0 was zero. Find the displacement at t = 0.71 s and x = 1.21 m. A) 3.47 m B) 1.62 m C) 7.00 m D) 5.45 m 2) 3) Transverse waves propagate at 43.2 m/s in a string that is subjected to a tension of 60.5 N. If the string is 16.1 m long, what is its total mass?
