I know there may be different types of cork, but let's take the "average" cork used for cork board, at say, 0.24gm/cm^3. Let's say you make a boat out of that cork. I understand that the weight of water displaced should be greater than the object's total weight (e.g. density of cork less than...
So, using the watch example, having a vacuum sealed case is worst than not having a vacuum at all (e.g. 0 ATM vs 1 ATM, respectively, on the inside of the case)?

I guess what I'm asking is how do these large mammals survive deep dives? Why aren't they destroyed by the water pressure? Is it because of the water displacing the air, or is it the absence of air preventing "the squeeze" feeling?
If I had a wristwatch that went deep into the water, and it's...
Large ocean/sea mammals, say a blue whale, are able to withstand large water pressures underwater, and I read that they're able to do so for a number of reasons, one of which is that the air cavities are thought to fill with water. Is it this equalization of pressure that allows whales to deep...
Thanks for the answers. :)
I was wondering if there were other forces, maybe even buoyant forces that would be significant.
But from what I can tell, it seems like the major ones are water and air pressure.
If you have, say, two tubes of different internal pressures submerged to a given depth (for sake of the example, let's just say 1,000M underwater or 100 ATM), will the smaller internal air pressure tube experience a greater relative force from the water pressure? The water pressure on both tubes...
