Problem 3. {Sound waves in different mediums} Substance Density ,0 (kg {m3} Speed 1; {m/s) Drv Air {STP} 1.217 340 Fresh Water [20 C} 9.982 x 102 1.41 x 103 Seawater {20 \"C} 10.25 x 102 1.54 x 103 A sound wave travels in the +xdirection through a straight pipe lled with seawater {20 C}. The frequency' of the wave is 1000 Hz. Suppose that at t = 0.0 s and at x = 0.0 m the gauge pressure is a maximum. A. At t direction? 0.0 5, what isthe location {in m} of the next maximum pressure in the +x B. Suppose, instead. the sound traveled through drvr air, which of the following quantities would change? a. Speed b. Wavelength c. FrequencyI C. At t = 0.0 5, what is the location {in m} of the first maximum away from the origin for sound traveling through dry air in the +xdirection
