š§µ How do sensors actually work?
Anonymous at Thu, 12 Sep 2024 21:00:18 UTC No. 16377547
What do we mean when we say the sensor 'sends a signal'? *How* does it do so in response to some input like temperature changes?

When I read text, especially when I try to focus on it, I unconsciously end up reading it out loud in my head.
I've heard that this is a bad habit. Is that true? If it is, how can I fix it?"

From a scientific perspective, would encountering sapient aliens awaken a new primal fear in us? We are accustomed to being the dominant and unchallenged species on the planet, so would meeting beings that are from foreign worlds with intellect and technology that surpass our own make us feel unnerved on an existential level?

Why doesn't all of the gas in the atmosphere escape into space?
>Because gravity
Gas molecules on the surface of earth where gravity is the strongest can overcome it and go directly up (pic rel), so shouldn't this be even less pronounced in the upper atmosphere where gravity is weaker?

Help with chemistry homework. Equilibrium problem
Question:
For the equilibrium
CO(g) + H2O(g) CO2(g) + H2(g)
the equilibrium constant is 4.0 at 800 K. In an experiment, 1.0 mol of carbon monoxide, 2.0 mol of water vapor, 3.0 mol of carbon dioxide and 4.0 mol of hydrogen gas were introduced into an empty container with a volume of 20.0 dm3 Calculate the concentration of carbon dioxide in the container since equilibrium has been established at 800 K.
I have put up a ICE table and gotten the starting concentrations
[CO]i=0,05
[H2O]i=0,1
[CO2]i=0,15
[H2]i=0,20
I tried putting the concentrations at equilibrium C(eq) as
[CO]=0,05-x
[H2O]=0,10-x
[CO2]=0,15+x
[H2]=0,20+x
Since thats how the equilibrium was written. The equilibrium constant K=4 so:
4,0=(0,15+x)(0,20+x)/(0,05-x)(0,10-
And got that x1= 0,3268 x2= - 0,0108
The negative i cant use (?) and the positive one is too big to subtract from my starting concentrations. And when adding the x1 into the equilibrium equation i get K=9,74 so its wrong anyway.
Is there something im missing in equilibrium/acid base reactions/gas reactions/how to work with concentration when different amount of substance of each component is added?

How can someone dedicate so much time to a subject of study and yet be so perplexingly incorrect?
And why do lowly engineers think that their education makes them proficient at writing theoretical physics papers?
How do they get published?

Does this illustration of a photon traveling through space actually make any sense?
Apart from the fact that the field would be 3-dimensional why would it ALTERNATE between having a maximal magnetic field and having a maximal electric field? Shouldn't it have both at the same time?
I found that here:
https://vixra.org/pdf/1904.0147v1.p
Now if anyone could tell me whether this paper is schizo babble or actually trustworthy that would be much appreciated.

The structure of the fatty acid in palm oil looks a lot like a paraffin wax with 2 extra oxygens stuck on. Theoretically then, could you make an edible oil from petroleum by oxidizing parrafin wax with potassium permanganate or something and then esterifying it with glycerin? Could you make soap by doing the same thing but instead making the sodium salts of those synthetic fatty acids?

Is there any study, statistic, or survey that shows that most men are indeed "pedophiles"?
I would argue that it's natural and evolutionary advantageous for men to feel attraction towards fertile females, but is there any actual research that shows that this is common?
