When the dolphin is swimming directlyaway at 8.0 m/s, the marine biologist measures the number of clicks occurring per second to be at a frequency of 2500 Hz. What is the diff erence(in Hz) between this frequency and the number of clicks per second actually emitted by the dolphin?

Question

78. Dolphins emit clicks of sound for communication and echolocation.
A marine biologist is monitoring a dolphin swimming in seawater where
the speed of sound is 1522 m/s. When the dolphin is swimming directly
away at 8.0 m/s, the marine biologist measures the number of clicks occurring per second to be at a frequency of 2500 Hz. What is the diff erence
(in Hz) between this frequency and the number of clicks per second actually emitted by the dolphin?
