so how wring would it be to assume that the air in the glass has the same compressibiliity as the air around us. Would it be valid for making a simplified model..?
so you say that the air is liquid? Sounds interesting... But doesn't the temperature of air has to be quite low in order to be liquid??
Also, would it be valid to do the following:
Lets say we have the compressibility of air (C.a) and the compressibility of water (C.w)... If we are given...
I have a question regarding a project I am working with currently...
Air that is dissolved in water (there always is around 0,004% I think, in normal pressure and 20 degress celsius), is it "physically dissolved"? I mean is the dissolved air still gas or is just air-molecules "trapped"...
I'm currently studying the phenomena of air bubbles in water affecting the sound (as it affects the speed of sound) produced in the water... I actually have a model for how the speed of sound should alter with the amount of air in it...
but I've got som problem with a thing I found out...
that helped alot:)
was wondeirng further, what would happen if there would be two liquids with different salinity instead.. they would although thermal equlibrium not have same density... so would they mix-up by diffusion eventually by time?
I have always wondered why liquids of different densities don't mix up if put together with caution. As if you have a glass halffilled with cold water, you can with caution add another layer of warm water above the cold. You will see a clear boundry between the layers.
Is this something with...
i just read through this thread (breifly, so excuse me if I repeat something), and couldn't resit posting my opinion...
I believe that the paper will Not bend... argument are given that it has a distribution of mass, and that this will cause the paper to bend. But that isn't true at all, as...
i just discovered a cool thing.. if we use this instead:
(1+\sqrt{2})^{n}
than we will get the cool thing that, at n= even numbers, we will get an answer just below an integer with 999999... as decimals...
but if we have n= odd number, the answer will be just above and integer with...
didnt find anything corresponding on that link (might have missed it)...
quite a fasciniating number...impressive..
i don't get \frac{a + \sqrt{b}}{c}...
becase if i set a=4 b=5 c=6 I don't get that sort of cool number... actually, i didnt get any number like that by that method. what did...
I "threw" zero off, not onto, the line of numbers...
I'll let zero exist as a concept but not as a number. So when you subtract tvo equal numbers you get the concept zero, which is nothing. Similarly, if someone asks how many points exist on a line, the asnwer will be the concept infinity. So...
I'll have to confess that that is a little problemtaic... but for the moment, let just throw the result of x-x of the line of numbers... if something equal nothing, it doesn't exist on the line... at least for the moment... will think if I can get a better solution...
