Answer:
A) the pressure could crush the submarine
Explanation:
- The submarines are mainly used for defense purposes.
- In world war 1 and 2 the submarines played a vital role in the war.
- The submarines work according to the principle of buoyancy.
- According to this principle, when seawater is filled inside the tank in a required amount, the submarines sink.
- When the seawater is expelled, the submarine rises to above the sea.
- Most of the time, it dives deep into the sea, the hydrostatic pressure should be taken into account.
- If the hydrostatic pressure is not considered, the pressure could crush the submarine.
Answer:
a = 0,1[m/s^2]
Explanation:
First we need to indentify the initial data.
And using this kinematic equation we have:
![v = 4[m/s]\\v_{0}= 2 [m/s] \\t = 20[s]\\\\v= v_{0}+a*t\\a=\frac{v-v_{0}}{t} \\a= \frac{4-2}{20} \\a=0.1[m/s^{2}]](https://tex.z-dn.net/?f=v%20%3D%204%5Bm%2Fs%5D%5C%5Cv_%7B0%7D%3D%202%20%5Bm%2Fs%5D%20%5C%5Ct%20%3D%2020%5Bs%5D%5C%5C%5C%5Cv%3D%20v_%7B0%7D%2Ba%2At%5C%5Ca%3D%5Cfrac%7Bv-v_%7B0%7D%7D%7Bt%7D%20%5C%5Ca%3D%20%5Cfrac%7B4-2%7D%7B20%7D%20%5C%5Ca%3D0.1%5Bm%2Fs%5E%7B2%7D%5D)
