On the planet Arrakis, a male ornithoid flies toward his female companion at 25.0 m/s while singing at a frequency of 1200 Hz. The stationary female hears a pitch of 1240 Hz. Calculate the speed of sound in the atmosphere of Arrakis.
A typical adult ear has a surface area of 1.36 × 10-3 m2. The sound intensity during a normal conversation is about 3.78 × 10-6 W/m2 at the listener's ear. Assume that the sound strikes the surface of the ear perpendicularly. How much power is intercepted by the ear? number units
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?
A bat can detect small objects, such as an insect, whose size is approximately equal to one wavelength of the sound the bat makes. If bats emit a chirp at a frequency of 51.0 kHz, and if the speed of sound in air is 340 m/s, what is the smallest insect a bat can detect?mm

A typical adult ear has a surface area of 1.90 × 103 m². The sound intensity during a normal conversation is about 2.04 x 10-6 W/m² at the listener's ear. Assume that the sound strikes the surface of the ear perpendicularly. How much power is intercepted by the ear? Number i Units
A dolphin is swimming at 10 metres per second towards a scuba diver. The dolphin is emitting a ‘welcome’cry which has a frequency of 2980 Hz. What is the frequency that the diver hears underwater?
A stationary police car emits a sound of frequency 1200 HzHz that bounces off of a car on the highway and returns with a frequency of 1260 HzHz. The police car is right next to the highway, so the moving car is traveling directly toward or away from it. What frequency would the police car have received if it had been traveling toward the other car at 23.0 m/sm/s ?
Sound 1 has an intensity of 36.0 W/m2. Sound 2 has an intensity level that is 2.3 dB greater than the intensity level of sound 1. What is the intensity of sound 2?
A stationary listener hears frequency f1 from a source moving directly toward the listener with a speed of 20.0 m/s. When the listener then moves directly toward the source with a speed of 30.0 m/s, the detected frequency f2 differs from f1 by 33.0 Hz. What is the frequency (in kHz) of the source? Take the speed of sound to be 340 m/s
