A bat, flying at 4.70 m/s toward a wall, emits a chirp at 50.0 kHz. If the wall reflects this sound pulse, what is the frequency, in kHz, of the echo received by the bat? (vsound = 340 m/s)

A bat, flying at 20.0 m/s, emits a chirp at 40.0 kHz. If this sound pulse is reflected by a wall, what is the frequency of the echo received by the bat? (V sound = 340 m/s. unit in kHz)
3. A bat flying toward a wall at 6.0m/s emits a sound at a frequency of 35kHz. What is the frequency of the echo (sound reflected by the wall back to the bat) that the bat hear? Assume the speed of sound to be 343m/s.
A bat flying at 4.10 m/s is chasing an insect flying in the same direction. If the bat emits a 40.0-kHz chirp and receives back an echo at 40.4 kHz, what is the speed of the insect? (Take the speed of sound in air to be 340 m/s.) _______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...
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.)
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...
please answer question showing all steps and formulas 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...
Bats use the Doppler effect to determine their location. A bat flies toward a wall at a speed of 15 m/s while emitting sound of frequency 35 kHz. What is the frequency received by the bat? (hint: 2 doppler effects occur)
A bat flying at 17.1 m/s (ground speed) emits a 503 Hz sonar ping. The sound returns after 1.302 seconds at frequency 575 Hz. Assume the Speed of Sound in this type of air is 343 m/s. Determine the Velocity of the object, in m/s relative to the ground. Take "moving away" as Positive.
