gaitons Set 7, Due Mon, Mar 31, 2008 at 23:59 1. 1 . [1 point, 10 tries] A transverse wave is formed on a long skipping rope. The equation of the transverse wave is y=4.56sin(0.020πx+2.57πt) where x and y are in centimeters and t is in seconds. Find the amplitude of the wave. Answer: 4.56e+00 cm 2. 2 . [1 point, 10 tries] What is the wavelength of the transverse wave? Answer: 1.00e+02 cm 3. 3 . [1 point, 10 tries] Find the frequency of the wave. Answer: 1.28e+00 Hz 4. 4 . [1 point, 10 tries] Calculate the speed of the wave. Answer: 1.28e+02 cm/s 5. 5 . [1 point, 10 tries] The figure below shows a plot of displacement as a function of position at time t=0. It represents a sinusoidal transverse wave formed in a string traveling in the direction of decreasing x. The tension in the string is 3.64 N and its mass per unit length is 28.7 g/m. The amplitude is 4.2 cm. Calculate the wave speed. Answer: 1.13e+01 m/s 6. 6 . [1 point, 10 tries] Calculate the period of the wave.
