photons have no mass though. what about potential energy for the electric energy? i prob dont know what im talking about. does energy have mass?

>>10397762
You decrease the potential energy of the system and therefore its mass.

Dunno complex analysis. What does "entire" mean

1 gram of air is heavier than all of the light in the universe.

>>10397842

They have energy.
Where did that energy come from?

>>10397851
>Protons
good work brah. anyhow even if you meant photons, then gravity couples to mass-energy, not just mass, so you can for example talk about the gravitational pull of a collection of photons. so for example you could add up the gravitational effects of all the photons within some distance of the core of the milky way galaxy, and you'd find it's more (as measured from a few galactic radii away) than the gravitational effects of 1 gram of air

>>10397859
photon is not an atom and it has no mass
this is why everything else, including a single atom like hydrogen, cannot achieve the speed of light

>>10397885
>gravity couples to mass-energy, not just mass
if you don't believe me, look up kugelblitz

>>10397885
It has no rest mass.
It does have energy which can translate to mass.
If you take two empty mirrored boxes and fill one with photons while the other is "empty" the box with the photons bouncing around will weigh more for the same reason a compressed spring weighs more than when its uncompressed.
Physics: Its fucking weird!

>>10397850
......From whenever the photon came from. Could be thermal radiation, could be fusion.

>>10397894
photons do have energy but it don't have mass
the single purpose of gravity is to influence the future position of energy

black hole does not pull everything close to it, it eats the future of everything close to it

>>10397902
no mass is not weight
energy can do force and weight is a side effect of force

>>10397735
Heat pumps are basically applied troll physics.
You literally draw +300% of heating efficiency from "thin air" at almost all normal temperatures.

>>10397735
can we make this work? I think this could work with sand. After all it would essentially be a fluidized bed? Actually wait, the drawing is tilted making it even easier. we already have uphill water slides that operate at about that angle. Although waterjets are used rather than wind. Could there not exist a stable solution where a trough of water is held in place by air drag?

>>10397842
>one gram of air
Ah, but what about a gram of water?

>>10397914
Coefficient of performance aint the same as efficiency

>>10397744
Basically it gets heavier since energy is leaving it, lowering its temperature, making it less boiant.

>>10397960
Should've put efficiency in quotes- you still get 3 times more thermal energy than you invested out of thin air.

>>10397744
If you face it up on a scale it will weigh more due to the force of the photons leaving the light nozzle

>>10397744
Physicist Answer: Yes, the system has less potential energy, and therefore, less mass.
Engineering Answer: No.

>black hole does not pull everything close to it, it eats the future of everything close to it

So are you saying that a physical body near a black hole has the time taken from it?
How can time be attached to something, time is a measurement?
Since the body will experience change near the black hole surely it will change from moment to moment.

Or are you saying the black hole is like a madman with a gun and it shoots the physical body taking the future from the poor innocent planet??

if answer is a, then d is also an answer, so 2/4. If answer is b then only 1/4. If answer is c then only 1/4. if answer is d, then a is also an answer, so 2/4

That means the highest chance of getting it correct is 50%, so B is the actual answer

if I'm guessing from 4 options, and the goal is to land on B, then I only have 1/4 of a chance of getting the real answer.

Wait a minute why wouldn't this work if you had super duper strong magnets? I'm imagining the force diagram in my hard and I get that the force applied to the gentleman's legs induced a reactive force that pushes the metal back down, but you're still pulling up with the magnets right? And if the magnets move up, then the whole system should move up right? Can someone explain how retarded I am?

>mfw brainlets think calling something a question implies it has an answer

>>10399126
fellow brainlet checking in.
why do you assume the shoe plate wants to move up, instead of thinking the magnets want to move down? instead of the plate lifting up, the magnets would drop down

>>10399015
No, the wings will hit the legs of the control panel.

t. engineer

>>10399160
But they wouldn't because the guy is holding them up. The magnets pull the plate up, which push on the guys legs, which, if he is able to stay rigid, causes the magnets to rise, which pulls the plate further. So if the magnets are strong enough to overcome the force of gravity the whole system should rise right? Obviously not, but I can't figure out why.
>>10399142
:( just wasting time I guess

>>10399175
False, he is pushing down on the plate with more force than the magnets are pulling up.

>>10399156

>>10399175
ok think about it this way.
instead of a guy holding a magnet, just imagine bowling ball with a metal plate glued to the bottom, and a magnet glued to the top.
by your logic, the bowling ball should start floating and lift off into space or something, no?

>>10398578
>moving a train takes more energy than converting ore into a train
Fucking brainlets

>>10399179
Is this because he pushes with both a reaction force (always equal to how much the plate pushes on him) PLUS his gravity force?

That makes sense, and you're right it wouldn't. The example actually helped, thanks senpai.

Can someone explain why this one wouldn't work?

>>10399295
It would work, it's just physically impossible for us right now

>>10399295

If my understanding of physics is correct, it technically would work -- just not in the way it's depicted. Since it would take light twenty years to travel both ways, you would see yourself twenty years ago from the moment you stared into the the telescope -- and that's assuming you stood there staring into it the entire twenty years.

Let's do this with enough mirrors to feel the time lapse effect. Put a 10000 mirrors on Earth, put 10001 mirrors on the Moon, put cameras on multiple locations of Earth with people standing at the end of the lens at specific times when everything aligns. Make a movie about time travel.

>>10399567
>Am I stupid
yes

>>10399126
So the magnets exert a force on the plate, but the plate also exerts a force on the magnet.

>>10399088

The magnets and the plane want to go together, if a caterpillar held the magnets and lifted them up it could work. In order to do it you'd have to equal the attractive force between the magnet and plane.
It would be the same as lifting the chair you're sitting on.

Couldn’t he just loosen his grip a little and crouch?

Guys I really think the info graphic is missing something, if he were to crouch he might actually get somewhere. Just standing around doesn’t really do anything but if the man with the magnets makes a crouching jumping motion WITHOUT having his feet leave the metal plate, then there is no reason why it wouldn’t work. You just have to make sure you bend the knees and then jerk upward. The force exerted on the metal plate will be about one and a half times larger than the force exerted on the person. (I could post equations and/or pictures if necessary)

Typically, when given an multiple choice question of this form, we assume that one answer will be correct and each answer will be different or perhaps that more than one answer will be correct, but the content of each lettered answer will be different.

However, in this question, there are two answers A and D which are identical. This makes the question unsolvable because the entire concept of this being a right or wrong multiple choice question has been broken.

We are left to question are general understanding...
*Is only one answer correct? If so, it cannot be A or D because A and D are the same.
*Is any answer with correct wording correct? Then A and D are both correct. However, if we assume that A and D are the same answer listed twice depending on our definition of "choosing an answer (at random)", the answer could probably be 33%, a limit of some kind, or 0%... or well, I'm not sure I haven't gone through the logic, but regardless if C was 33% or a limit, it may be correct, but 33% and infinity are not listed only 0%. It seems 0% would be correct, however the fact that is correct contradicts the answer. In spite of that, however, it is the best answer other than no answer.

It is actually a pretty good explanation

>>10400829
It won't. Stick moves when atoms in it push next atoms, that push other atoms and so on. Movement of particles with mass is way slower than speed of light, therefore it would take longer time to send this information than a year.

>>10402703
No no no, you fucking retard. You don’t understand. If you move the stick it’s moving the stick. There’s no reason for sound waves to pass at all

>>10403658
When you push the base of the stick, you create a force in it. This force pushes along the stick until it reaches the tip, and moves at the speed of sound in the stick.
Essentially, extremely large space is non-euclidean and the stick bends.

>>10403671
>When you push the base of the stick, you create a force in it.
I have a Masters in Physics myself.

You are correct, but you’re going about it wrong. Although forces do operate much like sound waves, that’s not exactly the speed they travel at.

And not only that, the reason why he’s correct is that it’s a single continuous object. A wood stick is a bit simplified but just imagine if the stick were to be made of something largely immobile with a tight molecular structure. Theoretically the troll image is correct then. The stick WOULD move faster than the speed of light. Some form of transportation with quickly moving stickkkkks could be imagined in the far future where the stickkkkks maneuvered you through compartments to get you where you neeeded to be faster.

But of course this is the far future. Not likely to happen.

This, but unironically.

>>10408801
i was being sincere

0% is a paradox, because if 0% is the answer there is one option saying 0% out of 4, which is 25%. there isn't a single option that doesn't lead to a contradiction, including the 0% option. the definition of a paradox. spastic.

wait really? why not?

>>10398856
mega brainlet here, why wouldn't this work? The laser part, not the moon part obviously. Assuming that the space between mirrors is a vaccum.

>>10399317
yeah, they look at the obviously glued together bill and tell you to fuck off

>>10409397
The mirrors absorb minuscule amounts of the laser wavelengths and emit it as infrared waves (heat) but so little infrared is emitted the mirrors will not get hot, and due to the speed of light being insanely fast, even if the mirrors absorb close to .001% of the wavelengths, it moves quick enough to lose more energy than to gain, or sustain it.

>>10399317
Yes. Black people don't send mail.

Take a look again.

>>10409759
are you blind faggot

>>10403644
dafuq outta here normie

>>10403716
who the fuck would give you a master in physics, please never practice, you gotta be kidding

>>10397735
This is some 2010 shit ITT. I love it

>>10397949
Correct answer is 33.333 so the answer is C

Not really science but whatever

>>10400573
This is correct.

Ouch has to hurt.
But he means the pressure at the surface isnt high enough to push anything up into orbit.
The pressure in the atmospher is not as high as in your gif btw.

>>10409432
>all that
How about the simple fact that nothing can go faster than light, so the quick flap idea is unfeasible from the start.

>>10402702
no, correct order of operations has multiplication and division done in order from left to right. this is taught with pedmas but you forgot

>>10410198
no-arbitrage principle... you have to consider that if mkts are rational everyone would do that, and so it's impossible in equilibrium to "cheat" the market.

>>10403651
I think he means that it pokes the other person with the opposite end of the stick which would take a split second. But that’s because the stick is only moving a inch or two not a whole light year. This is just all very retarded lol

>>10401583
Wow. People are getting triggered by this because they misunderstand what it's trying to say.

>>10405183
>Scientific "facts" are just a consensus of opinions, any of which may be incorrect or inaccurate.
Scientifically one tends to assume they're inaccurate. Falsifiability uber alles.

>>10403261
Correct, you can't do this because the world is made of discrete sub-atomic particles, this only work is you are dealing with continuous matter e.g. 3D real numbers or R3, in R3 you can always find a number between another two numbers, that's why it works i think

Kind if ironic that the real numbers aren't really real, i mean they are uncountable for gods sake

>>10397744
No, there are the same number of electrons in the batteries as when you started.

>>10399015
Eventually the wheels will spin so fast that they rip apart and the plane will be destroyed.

x = 1+x/2
x - 1 = x/2
(x - 1) * 2 = x
2x - 2 = x
2x = x+2
2x - x = 2
x = 2

>>10412110
or just

x = 1 + x/2
x/2 = 1
x = 2

>>10412118
Ah yes, I finally understand what a beautiful equation looks like

>>10412118
What did you do to get from the first one to the second one?

>>10412110
Who the fuck taught you how to do algebra retard

>>10412155
Subtraction.

>>10412160
I figured it out on my own

>>10412162
x - x/2?

Oh yea, I guess that would just be x/2

>>10409495
did it died?

>>10399215
>>10405883

LOL as stupid as it is, i agree that i think this is the one that could actually work

you wouldn't end up higher than the plane you fell out of tho

>>10400337
Fuck you, common core is not the same thing as new math

>>10400339
lul

>>10401576
Wait a second isn't that just water.

>>10400345
the joke is funny but the math fails

i think they meant factor x^2 + y^2 or some shit

>>10412569
yes but

>>10413283
But this one works...

>>10398985
This is just the redshift/blueshift effect.
It'd make it higher frequency not higher amount.

>>10399234
It's basically similar to a mercury delay line but with light instead of sound.
I suppose this would be the most efficient form of memory storage for a super advanced alien civilisation.

>>10397735
Nah, it won't work. You know what hold the water is the air pressure pushing the water up. A little disturbance will destroy your imaginary upside down pool.

>>10413283
I mean... if you have some "super powerful" rubber band that's just the right absurd length, you could do this. There are a lot of factors to consider here in deciding what happens if you jump off just as it starts to rebound, but odds are if its strong enough to rebound, you're probably good.

I would be more worried about where and if it snaps.

>>10397744
In exothermic chemical reactions, mass is converted to energy, just as in nuclear reactions. It's just a lot less mass/energy. Not incalculable, but not measurable with commonplace apparatus either.

>>10409495
God I wish that was me

>>10408791
That's due to ClearType, nothing to do with jpeg

>>10399225

>>10415121
but they all work?

>>10416119
Can we get more like this? Just actual science phrased to sound fake.

>>10399255
No, image is saying you cut 1 bill in half, so you now have 2 pieces of 50% of a dollar. You take a second bill and cut two pieces from it such that you retain >50% of the bill. You apply these pieces to the previously mentioned 50% halves, giving you 3 pieces of >50% of a total dollar bill. You exchance these to the bank to (hopefully) make a $100 profit.

>>10399567
you slowly drain the water with every opening of the gates. think about it.
>gate opens
>ball floats up
>equal volume of water moves down through the gate
>gate closes, with more water having moved down, which has lost potentoal energy
