Hello, here we have to determine density of the unknown liquid.
00:04
And we notice that the block floats in this liquid with 4 .6 centimeters of the side of the block is submerged.
00:14
So here let's make this sketch, so that's a liquid, and the block floats in it, and 4 .6 centimeters of the side is submerged.
00:25
Now, then, this block is placed in water, and in water in water in it floats in it.
00:31
In the way that now 5 .8 centimeters is submerged.
00:44
We have to determine the density of this block.
00:48
Let's solve this problem.
00:50
In both cases, the block experiences gravity downwards and it experiences a bi -on force in the liquid.
00:59
Let's call it fb1 and the bi -on force in water...
