Answer:
12.64968 Hz
Explanation:
v = Velocity of sound in seawater = 1522 m/s
u = Velocity of dolphin = 7.2 m/s
f' = Actual frequency = 2674 Hz
From Doppler effect we get the relation
![f=f'\frac{v-u}{v}\\\Rightarrow f=2674\frac{1522-7.2}{1522}\\\Rightarrow f=2661.35032\ Hz](https://tex.z-dn.net/?f=f%3Df%27%5Cfrac%7Bv-u%7D%7Bv%7D%5C%5C%5CRightarrow%20f%3D2674%5Cfrac%7B1522-7.2%7D%7B1522%7D%5C%5C%5CRightarrow%20f%3D2661.35032%5C%20Hz)
The frequency that will be received is 2661.35032 Hz
The difference in the frequency will be
![2674-2661.35032=12.64968\ Hz](https://tex.z-dn.net/?f=2674-2661.35032%3D12.64968%5C%20Hz)

Well it does carry blood and oxygen! Sorry but I'm not sure about 2 and 4.
