Good day.
00:02
The topic is about atmospheric pressure.
00:05
Atmosphere exerts a certain force over a certain area.
00:09
Let's say if we have force exerted over the surface of the liquid, then the atmosphere exerts pressure on that surface of the liquid.
00:19
And as a result, the liquid should rise to a certain height.
00:24
So given if the liquid, if a straw is placed on that surface, as the result of air pressure or air, atmospheric pressure some water will rise to the to the straw now the height reached by the liquid inside the straw is inversely proportional to the density of the liquid so we say height is inversely proportional to the density that means the denser the liquid is the lower or the lower the height that it reaches inside the straw or in mathematical form we can say it can write it as h1, d1, equals h2d2, where your h is your height, d is your density, and one and two, can refer to different liquids.
01:18
So say, for example, we have some liquid and another is water.
01:26
So let one be water and two be other liquid.
01:40
It's given that the density of this liquid, is 10 times the density of water.
01:47
Now we wish to find the height reached inside the straw on that certain liquid with respect to the height that is reached by liquid water in its corresponding straw.
02:08
So we can write it in this form.
02:10
H2 is equal to blank h1...
