Textbook QuestionThe string in FIGURE P16.59 has linear density μ. Find an expression in terms of M, μ, and θ for the speed of waves on the string. 305views
Textbook QuestionString 1 in FIGURE P16.47 has linear density 2.0 g/m and string 2 has linear density . A student sends pulses in both directions by quickly pulling up on the knot, then releasing it. What should the string lengths L₁ and L₂ be if the pulses are to reach the ends of the strings simultaneously? 392views
Textbook QuestionThe wave speed on a string under tension is 200 m/s. What is the speed if the tension is halved?462views
Textbook Question(II) A 0.40-kg cord is stretched between two supports 8.7 m apart. When one support is struck by a hammer, a transverse wave travels down the cord and reaches the other support in 0.85 s. What is the tension in the cord?94views
Textbook Question(II) A 4.4-kg ball hangs from a steel wire 1.00 mm in diameter and 5.00 m long. What would be the speed of a transverse wave in the steel wire?100views
Textbook Question(II) A ski gondola [pronounced gon–do–la] is connected to the top of a hill by a steel cable of length 710 m and diameter 1.5 cm. As the gondola comes to the end of its run, it bumps into the terminal and sends a transverse wave pulse along the cable. It is observed that it took 17 s for the pulse to return. (b) What is the tension in the cable?95views
Textbook Question(I) A transverse wave on a wire is given by D (x, t) = 0.015 sin ( 35x - 1200 t) where D and x are in meters and t is in seconds. (b) What is the speed of either wave?91views
Textbook QuestionA 10.0-m-long wire of mass 138 g is stretched under a tension of 255 N. A pulse is generated at one end, and 20.0 ms later a second pulse is generated at the opposite end. Where will the two pulses first meet?100views
Textbook QuestionA uniform cable 2.0-m long hangs vertically under its own weight.(a) Determine the speed of waves on the cable as a function the distance y (positive down from the top of the cable, where y = 0 ).102views
