And this question, you are looking at substantion, right? you have a liquid and you imagine you want to place an object in this liquid and this object can be supported, right, because of substantial, even if the object is heavier than the water, right? so you ask it actually to find a possible expression for this height of this block, right? the height, the thickness, sorry, the thickness of the block, h, which is, you know, has to be a kind of a combination of this few quanties air, row, g, and sigma.
00:41
Sigma is substantial.
00:42
Usually you expect that when sigma is bigger, the, this hedge will be, way be bigger, right? so, and when air is too big, it's not good, right, because air is the side of the square, right, of the, of the, of the, side of the square.
01:00
So when air is big property, it's too heavy and it does not support much of the h anymore.
01:05
So, and it's similar for g for row.
01:07
And actually, if you, so basically you can imagine that, and of course, h has dimension of lens.
01:15
So this combination, you have to give them some, give them some, some, some, it's pollen.
01:22
Let's say, i call it a, b, c.
01:24
C, d, right? and you need to choose this abc to that...
