Just know that there are multiple equivalent statements of 2LT. The Boltzmann formulation, which you just said, obviously comes from stat mech. But there is also the Kelvin-Planck statement, the Clausius statement, etc. All of these can be shown to be equivalent.
The fact that total entropy always increases as stated in >>11183917 follows directly from the Clausius inequality, which as a theorem must be proven once you assume the 2LT.

[eqn]L\ddot{Q}+R\dot{Q}+Q/C=E[/eqn]
for an RLC loop. Notice that inductor gives the second order term, the resistor the first, and the capacitor the zeroth. In a spring-damper-mass system, the mass gives the second order term, the damper the first order, and the spring the zeroth.
In this analogy, a capacitor is more like a spring, a resistor is more like a mechanical damper, and an inductor is more like inertia.

The government does not have the authority to mandate that you inject your child with anything. Not vaccinating a child is irresponsible, but not criminal or abusive. Anti-vaxxers are generally hugely misinformed/scientifically illiterate, but that doesn't mean you get to make a bloated, authoritarian state even more bloated and authoritarian.
Besides, all these retards' kids dying of whooping cough or whatever is an ecological positive.

"b is to a as a is to a+b" is the definition of the golden ratio.
So,
[math]\phi=\frac{a}{b}=\frac{a+b}{a}=1+\frac{b}{a}=1+\phi^{-1}[/math]
Multiply by phi to get
[math]\phi^2=\phi+1[/math]
Solve the quadratic to get the positive real root
[math]\phi=\frac{1+\sqrt{5}}{2}\approx 1.618[/math]

the golden ratio doesnt appear in nature nearly as much as /x/ niggers claim it does

I told you exactly what you need to do, you just need to plug in numbers and use a SUVAT eqtn. What more could you be confused about?

Stop making excuses. The chances of you being the dumbest in the room is small. And if you suspect you're a dum dum, what makes you think you can self learn? I don't think you think that about yourself, I just think you have anxiety over losing your NEET status. I implore you to think about going back to school. It is never too late. All the best of luck~

When I learned more about ODEs. They are simple enough, it's fine to just read about them when it comes time to apply them to something practical.

Sad!

Yes

Because non-newtonian fluids are just fluids whose shear rate is not linearly proportional to the shear stress applies (their viscosity is not constant at a given temperature). They are true fluids, nothing to do with a solid in suspension . Btw, no fluids are truly "newtonian" the closer you look.

The lore gets deeper. You seem to not like being called by your first name. Why? What would you prefer me to call you?

What forces are on the airplane? Thrust from the prop, and normal force from the wheels. The wheels apply no torque are are free to spin as fast as they need. The prop sends the plane forward, putting air over the wings, giving it lift. Thus it takes off. The motion of the conveyor belt doesn't interact with the plane in any way.

You got four unknowns with four equations given, pretty straight forward. Next time >>>/sqt/

>Are traps gay?
Unequivocally "yes"

Less air resistance
Customized outfits and appearance
Not limited to a single color scheme
Adjustable insulation/heat transfer

>What are the various ways machines draw information from the environment?
By mechanical interaction, by absorbing heat/radiation, by interacting with temperature gradients, electromagnetic fields, etc etc. Thats a pretty vague question. Specifically, what kind of interaction are you curious about?
>How could we extract information from the universe more precisely and with greater abundance?
By getting gud at engineering.
>is data stored in light
No. If i scratch tally marks into a piece of metal, i am not storing any data in light.
