2. Speed on a string Two strings have been tied together with a knot and then stretched between two rigid supports as in the figure. The strings have linear densities µ₁ = 1.4x10+ kg/m and μ₂ = 2.8x10 kg/m. Their lengths are L₁ = 3.0 m and L2 = 2.0m, and string 1 is under a tension of 400 N. Simultaneously, a pulse is sent on each string from the rigid support end, toward the knot. Which pulse reaches the knot first? 4₁ L₂ Knot

(a) Students in a physics lab are asked to find the length of an air column in a tube closed at one end that has a fundamental frequency of 256 Hz. They hold the tube vertically and fill it with water to the top, then lower the water while a 256—Hz tuning fork is rung and listen for the first resonance. What is the air temperature if the resonance occurs for a length of 0.336 m? (b) At what length will they observe the second resonance (first overtone)?

Why is the following situation impossible? Two identical loudspeakers are driven by the same oscillator at frequency 200 Hz. They are located on the ground a distance d = 4.00 m from each other. Starting far from the speakers, a man walks straight toward the right-hand speaker as shown in Figure P17.4. After passing through three minima in sound intensity, he walks to the next maximum and stops. Ignore any sound reflection from the ground. Figure P17.4
