In each of the four scenarios, a large bat lets out a short burst of ultrasonic sound, which the smaller bat hears a moment later. If the large bat flies at 2.870 m/s and the small bat flies at 15.60 m/s, rank the frequency that the smaller bat detects in the four scenarios, from highest to lowest. Assume that the speed of sound is 343.0 m/s. In scenario C, some of the large bat\'s signal reflects off of the small bat and returns to the large bat, warning it of the smaller bat\'s presence. If the initial signal has a frequency of 45.50 kHz, what return frequency will the large bat detect? Calculate the final frequency to four significant figures.
