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 needs to be in hertz

As a bat flies toward a wall at a speed of 6.0 m/s, the bat emits an ultrasonic sound wave with frequency 30.0 kHz. What frequency does the bat hear in the reflected wave? Ship A is traveling 20 m/s due east. Ship B is traveling 15 m/s due west away from Ship A. Ship A sounds a horn with a frequency of 1500 Hz. What frequency does an observer on Ship A hear in the reflected wave from Ship...

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.)

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...
