Two dolphins are swimming underwater in the same direction in the gulf of mexico. Dolphin A, swimming at Va = 5.0m/s, is ahead of Dolphin B, swimming at vg = 4.0m/s.. If Dolphin B makes a 2000 Hz call, what is the frequency heard by Dolphin A? (The speed of sound in seawater is 1530 m/s).
a. f = f v - vA/v + vB.
b. f = f v - vA/v - vB.
c. f = f v + vA/v + vB.
d. f = f v + vA/v - vB.
