- A pair of eagles are swooping in on the same prey between them, moving towards one another. One moves 15.0 m/s while the other travels at 20.0 m/s. The slower eagle produces 3.200-kHz cry, while the other responds with a 3.800-kHz cry. Taking the speed of sound to be 330 m/s, determine the frequency each eagle perceives.arrow_forwardMeatloaf (google/youtube him if you’re too young to know the reference) plays an F on his guitar as he races down the highway at 100.0mph on his motorcycle. (The song “Bat out of Hell” is in F major.) An F has a frequency of349.23Hz. First convert 100mph to meters per second. What frequency will a person standing along side the road hear as meatloaf approaches? (Hint, use the Doppler equation we derived in class. The speed of sound in air is 343m/s.)arrow_forwardA 440.-Hz tuning fork is held above the open end of a water-filled pop bottle and resonance is heard. The length of the pop bottle (bottom to top) is 28.2 cm. If the speed of sound is 345 m/s, then to what height is the pop bottle filled with water?arrow_forward
- A 38.0-Hz sound wave is barely audible at a sound intensity level of 60.0 dB. The density of air at 20.0°C is 1.20 kg/m3. Speed of sound in air at 20.0°C is 343 m/s. What is the displacement amplitude of a 38.0-Hz sound wave? What is the ratio of the displacement amplitude to the average distance between molecules in air at room temperature, about 3.00 nm?arrow_forwardA fire engine siren emits sound at 1260 Hz. The fire engine is driving down the street toward you at 29 m/s. (The speed of sound in air is 343 m/s.) What frequency sound do you hear?
