lai (yl8859) – HW24 – Ross – (15200) 1 This print-out should have 7 questions. Multiple-choice 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 kg μ = 0 0 . 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 ω t ) , where A = 0 . 12 m, k = 0 . 71 m 1 , and ω = 56 rad / s. If the mass per unit length of this string is 12 g / m, what is the power transmitted by the wave?

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
