Oscillator Type Question: A ship uses a horn to signal to other ships. The horn emits a soun intensity measuring 120 dB at 1 m using a point detector, with a frequency of 150 Hz. The horn is at approximately sea level at a temperature of 10°C. a. If the reference intensity of sound in air is 1 pW/m², what is the total power of the horn? b. If the ambient sound of the ocean is about 50 dB, at what distance will the horn be difficult to he How long will it take the sound of the horn to cover this distance if the air is mainly N2 with a molar mass of 28 g/mol and an adiabatic ratio of 7/5? C.
