Deep-sea diving vessels have to withstand pressure from the crushing effect of sea word(A) Upwards (0) Downwards(C) Side wayin all directions

Answer»

Answer:d) in all directions

Explanation:

The pressure at a depth h in water is calculated using

P = ρ g h

So, this pressure has a high magnitude at a large depth.

But, also note that the pressure is same in all directions at a given depth. So, the submarine will experience a pressure on all of it's walls whether they are below or above. Imagine holding a banana in your hand and crushing it b closing your fist. The same would happen to the submarine. Hence, the answer is (d) in all directions.
