Displacement question.

[teamonkey]

no no no

in both examples of mine, the same amount of water is displaced

the volume of the cube in the water is 10x10x9

therefore the volume displaced by the cube is always going to be 10x10x9

that volume will not change no matter how big the bath is provided that bath itself is larger than 10x10x9

no substitue the cube for celtic, and change the shape of the bah from a cube to a "celtic" and you will see that i am right

it's not about how much water is still in the bath, its about how much water the item, ie celtic, displaces, if there is still water in the bath and the "celtic" is not touching any surfaces, then he is floating

So what if you take your 11 x 11 x 10 bath and only half fill it with water meaning that there's only 605cm cubed available to be displaced.

Will your 10x10x10 float now that there isn't 900cm cubed available to be displaced in the first place?

imagine that the bath of 11x11x10 is a complete cube, in effect it is open topped, but imagine it as a cube

the volume of that cube would be 1210 cubic cm

if you put in 605 cubic cm of water, the other part of that, the volume above the water, would be 605 cubic cm of air

as you start to lower the 10x10x10 cube into the bath you start to displace the air, then when the cube touches the water and starts to lower into it, the water level appears to rise, but until the water reaches the top the volume of water in the bath is still the same, the only thing changing is that there is more "cube" and less air.

once the water starts to overflow, there is no more air left to displace, and it is water being displaced instead

eventually the cube will no longer go any lower in the water, and will, in our example, have 1cm above the water level (10x10x1 cubic cm)

does that make sense now? 

i'm not a teacher, btw, so it could well be my explanation that is lacking

This is so much fun

Yes I know what you're saying now.

If we assume a 10x10x10 cube with zero density.

In order for that cube to sink in water so that only 1cm was exposed out of the water you'd need 900cm cubed of water in it.

Now whether you put that cube in the ocean, a bath, a bucket or a cube of 10.1x10.1x10.1cm there's always going to be 1cm of cubed exposed at the top.

How's that

So basically we need to put celtic in a blender, thivken him up a bit so he's the same density as water, transfer him to a bath then stick that bath in a slightly larger bath to prove that he'd float.

Sounds like something for the next blonde bash.

This is like tag-debating. Who's next up?

Close enough for non science types, glad we have sorted this out.

Now, is Celtic hungry or not

You just lost all credibility!!!

Bobalike and Evilpie look like they should be 2 extras from football factory yet here they are showing us they are some of the finest minds Blonde has.

No wonder the site is in decline....
