A bat flying at 5.20 m/s is chasing an insect flying in the same direction. The bat emits a 39.8-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? ?m/s(b) Will the bat be able to catch the insect?
Yes or No
Explain.
While hunting for moths to eat, a bat emits a chirp that lasts for 2.10 ms and then is silent while it listens for the echo. If the beginning of the echo returns just after the outgoing chirp is finished, how close to the moth is the bat? The bat is flying toward the moth at a speed of 4.40 m/s and the moth is flying away from the bat at 1.20 m/s. Assume it is a cool night with a temperature of 10.0°C. Speed of sound in air at 0°C is 331 m/s (see table 12.1). in cm
