A bat flying at 3.00 m/s is chasing an insect flying away from it at a speed of 5.00 m/s. The bat emits a 40.0 kHz chirp which is detected by the insect. What is the frequency of sound detected by the insect, assuming that the insect can actually “hear” the chirp emitted by the bat? (The speed of sound in air is 343 m/s.)

A bat flying at 4.85 m/s is chasing an insect flying in the same direction. The bat emits a 39.9-kHz chirp and receives back an echo at 40.6 kHz. (Take the speed of sound in air to be v = 343 m/s.) (a) What is the speed of the insect? Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake...

A bat searching for prey emits sound at 90 kHz. The bat flies at 9.0 m/s. The sound emitted by the bat reaches a moth at rest. What frequency is the sound once it reaches the moth? Take the speed of sound in air to be 343 m/s. The moth now flies away at 2 m/s. What is the difference between the frequency that originally reached the still moth and the frequency reaching the moving moth? answer to second part...

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 54.5 kHz, and the speed of sound in air is 339 m/s, what is the smallest insect a bat can detect?

Some bat species eat up to 1,000 mosquitoes in an hour. A bat, flying with a speed of 4.36 m/s, is in pursuit of a mosquito. While in motion, the bat produces a 39.70 kHz sound and hears the sound which is reflected off the mosquito at a frequency of 40.36 kHz. (Assume the speed of sound in air is v = 343 m/s.) How fast is the mosquito flying (in m/s)?

009 10.0 points 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 26.2 kHz, and the speed of sound in air is 334 m/s, what is the smallest insect a bat can detect? Answer in units of mm.

1. A bat emits a sound at a frequency of 12 kHz as it approaches a wall. The bat detects beats such that the frequency of the echo is 860 Hz higher than the frequency the bat is emitting. The speed of sound in air is 340 m/s. The speed of the bat is closest to 2. A supersonic plane passes overhead at a speed of 823 m/s. If you hear the sonic boom (shock wave) 4 s after the...
