The ability to hear a "pin drop" is the sign of sensitive hearing. Suppose a 0.53 g pin is dropped from a height of 31 cm, and that the pin emits sound for 1.4 s when it lands. Part A Assuming all of the mechanical energy of the pin is converted to sound energy, and that the sound radiates uniformly in all directions, find the maximum distance from which a person can hear the pin drop. (This is the ideal maximum distance, but atmospheric absorption and other factors will make the actual maximum distance considerably smaller.) Express your answer using two significant figures.

A Kundt's tube is filled with helium gas. The speed of sound in helium at 20°C is 999 m/s. A tuning fork that produces sound waves with frequency 1200 Hz is used to set up standing waves inside the tube. You measure the node-to-node distance to be 47.0 cm ▾ Part A What is the temperature of the helium gas in the sube? Express your answer in degrees Celsius.

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…

The hand moves the end of the Slinky up and down through 8 complete cycles in one second. The wave moves along the Slinky at a speed of 49 m/s. Find the distance between two adjacent crests on the wave. No need to include the unit. Write your answer in whole numbers.
