By velocity, you are referring to the speed of sound. It can be modelled by the equation:

V = 331m/s + (0.6m/s/C) x T (where T stands for temperature and V stands for Velocity).

Plug in the numbers and you'll get 343m/s

Please help: What effect does eutrophication have in aquatic ecosystems?
Alisiya [41]

Answer:

The answer is D

Explanation:

an overabundance of nutrients primarily nitrogen and phosphorus which is in the water starts a process called eutrophication which makes it decrease. when the algae dies they are decomposed by bacteria. This process consumes the oxygen dissolved in the water which is needed by fish and other Aquatic Life to breathe.

It isn't C because it actually increases carbon dioxide not lower.

It isnt B because it does negatively impact aquatic vegetation but it is not beneficial for all aquatic animals

A isn't the the correct answer because eutrophication has nothing to do with sunlight into the ocean

So the only answer left which is correct is D

(I hope this helps you! have a wonderful day everyone!)
