Multiplechoice questions may continue on the next column or page find all choices before answering. 001 10.0 points A phone cord is 6 . 23 m long. The cord has a mass of 0 . 212 kg. A transverse wave pulse is produced by plucking one end of the taut cord. The pulse makes four trips down and back along the cord in 0 . 851 s. What is the tension in the cord? Answer in units of N. 002 10.0 points A 2 . 8 kg block supported by a string rests on a frictionless incline. The length of the string is 0 . 2 m and its mass of 1 . 8 g 2 . 8 kg. 2 . 8 k g = . 2 m 26 Determine the time it takes a transverse wave to travel from one end of the string to the other. The acceleration of gravity is 9 . 8 m / s 2 . Answer in units of ms. 003 10.0 points A sinusoidal wave on a string is described by the equation y = A sin( k x t ) , where A = 0 . 12 m, k = 0 . 71 m 1 , and = 56 rad / s....
