At t = 0, the instantaneous position of two pulses moving along a taut string with a speed v = 2.16 cm/s are as shown in the diagram below. Each unit on the horizontal axis is 5.0 cm and each unit on the vertical axis is 2.0 cm. у (ст) pulse 2 x (cm) pulse 1 (a) At what location and time will the midpoint of pulse 1 coincide with the leading edge of pulse 2? location cm time (b) What is the y-value of the resultant wave at the time and location determined in part (a)? ст (c) At what location and time will the midpoint of pulse 1 coincide with the midpoint of pulse 2? location cm time (d) What is the y-value of the resultant wave at the time and location determined in part (c)? cm

0.0058 kg/m is fixed at both ends. A 5.0-kg mass is hung from A string with a linear mass density of the string, as shown. If a pulse is sent along section A, what is the wave speed in section A and the wave speed in section B? %D B. A FA 35° 5 kg Image Description VA m/s VB = m/s B.

We will assume that a sound wave, once generated and emitted, will propagate uniformly in all directions of 3-dimensional space. Find an expression for the displacement s(r, t) of the air particles from equilibrium, where r is the radial distance from the source, and t is time. Introduce physical constants/coefficients, with appropriate physical dimensions, when necessary.

Please download the following worksheets, which show 4 separate grids. Each grid has two different waves (e.g., Wave and Wave B). Your goal is to draw the resulting wave (i.e., Wave C) if the two waves would have been superposed on top of each other. To do this, you'll need to add the two amplitudes (height of the Wave A and Wave B on the y-axis) at a given point on the x-axis to get the resulting one. For example, using number 3 as an example: a. At point 0 on the x axis, Wave A has an amplitude of 0, and Wave B has an amplitude of 0, so Wave C at point 0 would be 0. b. At point 4 on the x axis, Wave A has an amplitude of 6, and Wave B has an amplitude of 4, so Wave C at point 3 would have an amplitude of 10. c. At point 8 on the x axis. Wave A has an amplitdue of 0, and Wave B has an amplitude of -4, so Wave C at point 8 would be -4. You do not have to find the points for every single point along the x-axis, but just enough to get the general shape of the resulting wave. Once you…
