Question

the LRS is tested in fresh water.The density of fresh water is 1000 kg? Explain why the pressure on the submarine in the fresh water is less than the pressure in sea at the same depth​

Answer 1

Answer:

Answer is simple. the density of the sea water is 1029kg/M3.

Explanation:

so, if you compare both the scenarios you'll get to see that we can even swim easily in sea water rather than fresh water. let me show you in equation.

rho-w - 1000, rho-s - 1029. g is same h is depth which is also same

rho-w*g*h = rho-s*g*h

here you can see that the total pressure on the submarine in sea water will be more as compared to fresh water.
