On a 20°C night, a bat hovering in the airemits an ultrasonic chirp that has a frequencyof 45 kHz. It hears an echo 54 ms later.a. Suppose the bat's timing uncertainty is ±1ms; that is, what the bat perceives as a 54 msdelay could actually be anywhere in therange 53-55 ms. What is the uncertainty inthe distance to the object?b. Suppose the object is an insect flyingstraight away from the bat. What is theinsect's speed if the ultrasonic echo is shifteddown in frequency by 750 Hz?
