If you look at the attachment (don't mind my awesome paint skills ), which container experiences the greatest pressure at the bottom of the fluid? 1, 2, 3, or all 3 experience the same pressure at the bottom.
Thanks so much!
Thanks so much!
So pgh doesnt apply here? But instead F/A?
I think they have the same pressure regardless of the shape of the containers (assuming the fluid densities are the same) since the depth are the same. P = density*gravity*height
You can't apply P = F/A in this case. The pressure at the bottom of each container is the same. Assuming the height of the fluid is 10cm...if the pressure is the same at 5cm depth for each container, why would it be different at 10cm depth(which is the bottom of each container)?Well maybe the same overall pressure but the question asked about the bottom of the container only. In the overall, the area would be the same for all three and the height will be the same as well so the pressure will be the same. But for just the bottom, the area is obviously different and thus choice A wins.
You can't apply P = F/A in this case.
I guess it will work but requires more thinking. Are you saying P = F/A or P= mg/A... P = Vol*density*g/A...Remember that these vessels do not have the same volume of fluid...so the ones with less surface area will hold less volume of fluid...Therefore, the area is proportional with the volume occupied...We will end up with the same pressure. This formula will work as well but requires more thinking. Hope it makes sense.I don't see why not, can you explain?

Temperature101 is correct here.
Think about it this way. If you were to swim to the bottom of the deep end in a pool, no matter what the size or shape of the pool, you would feel the same pressure from the column of water above you. The pool may get wider, but at a given depth you are beneath a column of water that weighs so much per square meter no matter where you are in the pool or what shape the pool may be.
Here is my take on this tricky figure:
If the height of the water column level in each figure was the same with respect to the bottom of the container, then the pressure would be the same.
BUT
If the volume of the water in each figure was the same, I would think the left most figure would have the greatest amount of pressure. Why? Because the height of the water column would increase in the left most figure since there is less cross sectional area at the bottom of the flask. The left most figure would have the highest water column. The right most figure would have less water column height than the left most figure.. And the middle figure would have the shortest water column height. Since there is more area at the bottom of the flask in the middle figure, the water column would be lower than the other two figures because there is more space for water to occupy.
So both Donald Juan and Temperature101 are correct, because you both assumed different constants. You all are right and the figure is ambiguous.
This.

Feels great to be done, doesn't it? Here's hoping you have at least two teens when scores come back.
