Each of the main cables supporting a suspension bridge can be roughly modeled as a one-dimensional string of length 300 m, with a mass of 7.5 times 10^6 kg, placed under tension of 10 MN (Mega-Newtons)= 1.0 times 10^7 N. Suddenly, an earthquake creates a transverse wave in the cable with an amplitude of 1.60 m. a. What is the wave speed? b. If the earthquake drives the wave with a frequency 1.3Hz, what is the wavelength? c. What is...

question 4-7 4. Travelling Waves and Their Characteristics A rope wave travels in the positive x -direction. You are also told that the speed of the wave is 1000 cm/s, its frequency is 200 Hz, and that the wave is subject to the following initial conditions: at x 0 and t = 0: y =-1 cm, and, at x = 0 and t : ar = +20 cm/s (this is the velocity of the point on the rope at horizontal...
