Answer:
b. Re
Explanation:
Reynolds number describe the type of flow of fluid. If Reynolds number has a high value then it is called turbulent flow and if Reynolds number is low then it is called laminar flow. Reynolds number given as follows:

For internal pipe flow, if Reynolds number greater than 4000 then, it is called turbulent flow and if Reynolds number less than 2000 then it is called laminar flow. The Reynolds number between 2000 to 4000 the flow is called transition flow.
Answer:horizontal
Explanation: because it is supporting it
Your muscles are supplying you with the energy to move through a biological process called <u>metabolism</u>.
<h3>What is metabolism?</h3>
Metabolism can be defined as a set of chemical and biological processes that are carried out by a living organism, in order to sustain life.
A good example of metabolism is the supply of energy by the muscles in the body of a living organism, which enables him or her to move from one point to another.
In conclusion, your muscles are able to supply you with the energy to move through a biological process called <u>metabolism</u>.

Answer:

So the bouy does not float with its axis vertical
Explanation:
From the question we are told that:
Diameter 
Length 
Weight 
Specific weight of sea water 
Generally the equation for weight of cylinder is mathematically given by
Weight of cylinder = buoyancy Force

Where

Therefore

Therefore
Center of Bouyance B

Center of Gravity

Generally the equation for\BM is mathematically given by

Therefore

Therefore

Therefore

So the bouy does not float with its axis vertical
