Sound travels fastest through a solid, because the molecules are most tightly packed together in a solid, helping the sound waves jump from one molecule to another faster. Sound travels second fastest through a liquid because the molecules are packed together second most, and sound travels slowest through gasses.
Sound travels fastest in solids, slower in liquids, and slowest in gasses.
Here are the methods that I think that kinesiologists might use to study physical activity. These are exercise and Skilled movement. According to Kinesiology, physical activity is any movement that is intentional, voluntary, and is directed to achieving a desired goal. Hope this answers your question.
What does this even mean is my answer

Answer:
<h2>The water tank have to support a pressure of 50,456 Pa.</h2>
Explanation:
To design the cylindrical, pressurised water tank, we need to calculate the total pressure that it's being applied to tank, in order to know how strong we need to make it.
The total pressure (P) on the tank is always the sum of all pressures that are involved, external air pressure (P1), inside pressure (P2) and the pressure due to the mass of water (P3).
So, The external air pressure (P1) is 95.0 kPa.
The inside pressure (P2) is 110 kPa.
The pressure due to the mass of water (P3) will be calculated with: 
; where p is density of the water, g is the gravity and h the height.
Using the values given g = 3.71 m/s2; h = 13.6 m and p = 1000 kg/m3.
Therefore, we need to design an water tank strong enough to endure a pressure of 50,456 Pa.
