Kevin is initially standing equidistant (d = 5.58 m) from two speakers which are separated by x₁ = 4.47 m as shown. Sound with frequency 410 Hz is being played in phase from both speakers. Speaker 2 is moved horizontally until Kevin again hears loud sound. Find how far (labelled x2 in the diagram) the speaker was moved from its original position. Give your answer in metres.

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.

Two loudspeakers emit identical sound waves along the x-axis. The sound at a point on the axis has maximum intensity when the speakers are 22 cm apart. The sound intensity decreases as the distance between the speakers is increased, reaching zero at a separation of 33 cm. Part A What is the wavelength of the sound? Part B If the distance between the speakers continues to increase, at what separation will the sound intensity again be a maximum?
1. Two speakers are 4.5 meters apart, in phase, and produce a single sound wave with wavelength λ = 0.8m. Three points labelled A, B, and C are 4.0m, 8.0m, and 12.0m below the speaker on the left, as shown. Fill in the table with the required information, and indicate whether the point sees Constructive or Destructive interference. (Hint: remember the Pythagorean theorem!) 4.5m A B C AL= L2 14₁-121 www.

(a) After J. J. Thompson experimentally discovered the existence of electrons in 1897, he went on to propose the plum pudding model of matter. What was the plum pudding model? What did Ernest Rutherford conclude about the structure of matter based on his experimental results from bombarding gold foil with alpha particles? (b) What was the proposed atomic model of matter put forward by Rutherford? Theoretically what was the problem with his proposed model of the atom? (c) What was the modification made by Niels Bohr to Rutherford's model, i.e., what were the assumptions that Bohr made for his version of the atomic model of matter? (d) What observational phenomena was Bohr's proposed model able to explain? How did his model explain these phenomena? (e) Draw an energy level diagram with one representative transition to support your answer to part (d).
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…
