Physics Problem: what % barrel floating above water
|
So it didn't sink huh?
You are currently experiencing a lucky and very brief window of awareness, sandwiched in between two periods of timeless and utter nothingness. So why not make the most of it, and stop wasting your life away trying to convince other people that there is something else? The reality is obvious.
 
You make people miserable and there's nothing they can do about it, just like god.

So, oil is poured "over" this cylinder, but not into it, and it is not a porous object?
Trying to update my sig ...

It will be somewhere around 7kg - the weight of the displaced oil. A little more math than that, but right now I am not in math 'mode'. It really comes down to how much oil is added to the water. If there is only a small amount at the surface, it isn't going to significantly affect the calculations. If, on the other hand, if there is a substantial amount, you have to factor in how much oil is displaced along with the water. If it's floating entirely in oil, the calculations become simple again, you'll just be displacing 7kg of oil instead of water. You really do need to know how much oil there is to do this problem.

I believe this is the standard buoyancy problem and there is enough oil to completely encompass the cylinder. In high school, mine was a block of wood.
