in each of the four scenarios shown in the images, a large bat lets out a short burst of ultrasonic sound, which a smaller bat hears a moment later. if the large bat flies at 3.750 m/s and the small bat flies at 13.60 m/s , order the frequencies that the smaller bat detects in the four scenarios from highest to lowest. assume that the speed of sound is 343.0 m/s . a. the large bat is on the left and is flying to the right. the small bat is on the right and is flying to the right. b. the large bat is on the left and is flying to the left. the small bat is on the right and is flying to the right. c. the large bat is on the left and is flying to the right. the small bat is on the right and is flying to the left. d. the large bat is on the left and is flying to the left. the small bat is on the right and is flying to the left.
