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...

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...
