wtf how can it be equal, a steel ball is heavier than a ping pong ball
because it's a drawing
They fall at the same speed
Then you add a portal that's moving towards the balls and this thread gets 400 replies.
It's just displacing the water dummy. Sticking your toe into the bathtub doesn't add 200 pounds to it.
steel is heavier than faythus
This is not quite equal though. Assuming the same volume of string is submerged in both containers, the full mass of the ping pong ball is acting downward on the scale whereas the mass of the steel ball is being supported OUTSIDE of the container and is thus not acting upon the scale.
>equal volume and thus weight of water on both sides
>weight of steel ball is supported outside the system
>weight of ping pong ball shell is within the system
the scale should be tipped slightly to the left
The steel ball is just displacing the water, but how is the ping ping ball not adding weight?
Okay but what's the puzzle here?
I give up the first puzzle of 999 door and watch walkthrough after that. I really don't have enough IQ for this game
It's floating and the string is pulling the scale up.
>the string is pulling the scale up
Ping pong balls float therefore pulling the left side of the scale up so the scale is going to tip to the right
wrong
No, he's right, you're just retarded and bumping a thread that deserves to die before it attracts actual retards and not just ironic shitposters.
kys
no, he's wrong. the steel ball is suspended by a string but it's still displacing the water which means it weighs exactly as much as the same volume of water would, and a ping pong ball weighs less than that. tips right.
left side is heavier
>ping pong ball is lifting the scale
Steel ball is displacing an equal amount of water, but adding no weight to the water so the total weight of the right side is less.
Haha, classic
It's attached to the string, and the string is attached to the flask thing.
Ah yes, the old "buoyancy is upward propulsion" theory.
the ball is full of air, it's not subtracting any weight, this is high school physics
No, it would add 400 lbs. in my case.
Air is less dense than water, meaning when placed in liquid it acts as a propellant and produces an upward force. In effect it behaves like a negative mass, floating upward instead of being driven towards the earth's gravity. The left side should therefore be lighter than the right.
What's heavier, Yea Forums? A kilogram of steel or a kilogram of feathers?
your mom lmao
a keelogram a steel, caz steels heavier than fethurs
The memories of my online friends who died.
Are we talking about velociraptor feathers or goose feathers.
The answer is Barry’s Red Cola.
>kuchceee
>glug glug glug glug
how refreshing.
...
The string on the ping pong ball is attached to the scale while the string on the steel ball isn't, so the ping pong ball side weighs more.
a kilo of feathers, cuz you'll carry the weight of what you did to those poor birds
>the string is pulling the scale up.
Jesus fucking Christ, user.
>game has puzzle section
>its just annoying and makes me look up the answer so I can keep playing
LEFT SIDE IS HEAVIER BUT THE SCALE IS SO SHIT THAT IT DOESN'T EVEN MATTER
Off-topic lure.
>what is buoyant force
I shiggt
But the ball itself is made out of plastic, and there's the string itself. It's a very small amount of weight, but it is there.
Technically the right side would bob up and down. As the string holding the ball is shorter, if the lines are even then that means that the left side actually has less water in it the the right, as the string is longer.
>equal ball size
>one string longer than the other
Means more displaced water, meaning one side has more water than the other and thus is actually heavier. (also you could get into things like fiber, vs poly string) Which would account for water displacement in the rights string soaking up and going up the string and causing a loss of water and thus a weight shift.
The steel ball does not add downward force to the right system, because it's weight is transferred outside the right system by the stand
The ping-pong ball adds both downward force (weight of the plastic) and upward force (buoyancy) to the left system, because it is contained within the system and the forces are not transferred externally (no stand)
Therefore, the answer can be found by:
(downward force of weight of the plastic) vs (upward force of weigh of buoyancy)
Whichever of these two forces is greater will determine if the left side rises or falls
This. The added weight of the ping pong ball is within the scale's margin of error and this goes undetected.
Please go attach a ping pong ball to a flask of water with string and record a video of the flask floating for me
Literally this
Everyone who thinks the plastic ball only adds weight and does nothing else is a fucking retard
>what is buoyancy
>what is tension
>hurrdrrr
The upward force of the buoyancy is cancelled out by the downward forced exerted on the water
LOOOOOL!
It still adds to the mass you moron.
I guess boats must be lighter than water, because buoyant force isn't real and can't be counteracting the weight of steel hulls.
That’s literally not what I’m saying, do you even understand how scales work
>hurr durr scales directly measure mass
Scales measure the total downward force directly, and from this we get mass indirectly.
and if you put a fan on a sail boat you don't need wind to move
You’re fucking retarded
See
Do you people realize both of these things can be true at the same time, or are you all seriously this gay
>if you put a propeller on a boat it won’t move because the water creates a convection current that pushes the boat backward
I'm retarded for being correct?
Holy fuck take a remedial physics class
Fans require power to do anything.
This is the only right answer.
Yeah, I saw that mythbusters where they did exactly that.
actual retards
stop embarrassing yourselves
I made all of these posts but unironically the ping pong ball is attached to the flask and everything within the flask is a closed system and any force acting on the inside of the flask doesn’t matter because at the end of the day the total mass of the flask is greater than the total mass of the other side and the ping pong ball isn’t attached to the scale
If the ping pong ball was attached to the scale, it would definitely change the total force acting on the scale and affect which side “weighed” more. But it’s attached to the flask. So the problem is a lot simpler than that.
That's not the right answer, the rudimentary graphic implies that the system is entire symmetrical, with the only differences being the material of the ball, and the method for which the balls are suspended.
You're just being the gay "but there are more water pixels on one side durr hurr" contrarian.
I think the image is supposed to assume that the weight is negligible, but you're right that the left side is heavier by exactly the mass of the ping pong ball if the two balls have the same volume.
The graphic is not symmetrical, nor is it stated anywhere that it is.
I don't get it
>my boat is a closed system so the buoyancy doesn't count and at the end of the day the boat will sink straight to the bottom of the ocean because only mass matters
Please shut the fuck up and die.
I never said it was stated, I said it was implied, because it is, which is why no exact dimensions are listed on the graphic.
You're not being clever. You're not being edgy. You're just being wrong.
The buoyancy of the boat isn’t attached to a string at the bottom of the ocean though
>Everyone saying the correct answer stated completely wrong reasoning
>LOL BUOYANCY UR ALL RETARDED
if you're gonna count the length of string displacing water, you've gotta count the ping pong ball mass as well. In fact, the ping pong ball could weigh exactly the same as the difference in mass of the displaced water due to string, causing it to be perfectly balanced.
>the rudimentary graphic implies that the system is entire symmetrical
[citation needed]
>implied
It's only implied because you wish it to be. From the graphic given the amount of string in the water is different in each cup, leading to a displacement difference meaning one cup 100% is factual, objectively, real world physics has more water than the other. Deal with it., also stop reddit spacing fag.
>being this buttmad he didn’t know the right answer
The ping-pong ball isn't attached to the ground under the scale either, therefore, the buoyant force is not transferred to the the ground, it's impacting the left side of the scale.
You really couldn't figure this out?
Your citation is it wouldn't be a intriguing question if one side was obviously heavier than the other
Holy shit learn to read a room dumbass
Dude I’m playing both sides and everybody is getting angry about it, don’t be a poor sport, I’m having this most fun out of everyone
>Literally replies to every person who disagreed with him
>Calls other people mad
Pathetic
There are no dimensions or values given in the graphic, which is crudely drawn, in what any reasonable person would assume is an attempt to be symmetrical.
[citation given now fuck off]
Look dude, for all we know that fucking nigger in that video used 1M acetic acid just to make sure the right side would be heavier
But steels heavier than ping pongs...
he copied those post numbers from my post
so he didn't personally curate those (you)s
Falls to the left because the left side is holding the extra weight of 1 ping pong ball, and the steel ball isn't part of the scale.
At least someone in this thread isn’t retarded...
The right side is heavier, because the water is absorbing the energy exerted from the force which is known as "Gravity", which we all know affects heavier objects (Steel, as opposed to the lighter Plastic) more than lighter objects such as Plastic
retard
The right side does fall but your answer is not correct
Completely incorrect
See
Was just going to post this, as the weight of the ping pong ball and string are so negligible that they may just be equal. Also depends on the scale's level of resistance, some need a certain level of weight to move, it's usually not much but the tolerance is usually more than the weight of a ping ball and a centimeter of string
The intrigue of the question isn't, at any point, called into question by the graphic. From an objective standpoint, there is more water in the right cup based on what's seen in the graphic and the immediate geometry involved. Fuck the room; if you can't extrapolate an objective answer from a question posed by a graphic explicitly designed to ask a question with visual data alone, then the graphic fails at it's intended purpose and you need to make a better one.
The scale itself isn't even symmetrical, but only by a few pixels.
Symmetry is implied. Asymmetry is not, and it is is not part of the puzzle.
You realize there are many scales with varying degrees of accuracy, right m8?

Everyone here has said that buoyancy lifts the ping pong ball which the video shows is incorrect. No one took into account that the steel ball actually does exert a force on the water because of the removed tension in the string. We all assumed it was independent of the system.
>HAHAHA I REPLIED TO EVERYONE, NOW WHAT
This is literal autism. You can't even deal with what someone else posted so bad that you went and made this.
autistic
(science brainlet here) but wouldn't the steel ball still be imparting some kind of force because it's displacing the water?
Is this a good thing for games though?
One thing is reasoning and basic maths, but here we're talking about a problem that arguably only people with the prior knowledge of buoyanci and how force works. Maybe i just went to a shitty high school.
It's not autism, you're just trying to be edgy.

I'M TREMENDOUSLY FUCKING SURPRISED. GOOD NIGHT.
user, I think you've had enough internet for today. go to bed.
It does, same with the ping pong ball since they're same volume.
Difference comes from the string tension on the left, reducing the displacement force from the ping-pong, hence making the right side heavier.
>Also depends on the scale's level of resistance
That is exactly correct.
Baba

Love
That's a good example of well-crafted puzzles but honestly I find a bit too restricting once you get into the later levels and there's no room for trial-and-error anymore, only the one specific sequence of moves that solves the puzzle
The string too
Eh, fair. I still give it to the devs for making such a joyous thing, but yes, the more complex the less freedom.
Ok now why wouldn't this work
But that part of my body starts floating partially dumbass, thus adding its weight to the water. If you let an arm float, you don't have to hold it up. Just because it displaces water doesn't mean it doesn't add anything to it, by your retard logic you could just infinitely add water to a pool and expect it to not get heavier because water displaces water, you fucking retard.
Ping-pong's weight and string are negligible. Only really matters the added weight from water displacement, both equal in either side, with the buoyancy difference.
If anything the string is what tips it right. The tension of the string should tip you off about that negative (upwards) force on the left.
All part of the same system. There is no pulling, at all. Same way pulling from your own shirt doesn't propels you forward.
The magnets are pulling towards eachother with equal force so it won't go anywhere
Your moms does
>But that part of my body starts floating partially dumbass
Only if you allow it to hang limply like the string in the example. Your body doesn't typically work that way though, chances are your muscles are still supporting all the weight instead of automatically releasing tension like the string does.
Chill my dude. user is wrong about it but so are you. It's not about adding water but what the water does to other water molecules. Incrising hydrostatic pressure is the key. The milliliters of water the a constant all throughout.
They're both one kilogram.
Not a good explanation. If you had a car in front pulling from one of the magnets you could have forward force. Magnets always do equal force...
It's about what the magnets are attach to. Both going to the same system will do nothing.
That was implied you fucking retard
If you stick your foot into a bucket of water, on a scale, without touching the bottom/sides, it'll increase the weight on the scale. The bucket of water "pushes up" against your foot, or in other words, he buoyancy of your foot "forces" the bucket of water down toward the scale. It's Archimedes' Principle
Why are you so angry. If you imply during an explanation, why explain at all? Also, magnets always have equal force, so you've said nothing of value or worth.
It's ok to be wrong user, hope you learned.
>If anything the string is what tips it right. The tension of the string should tip you off about that negative (upwards) force on the left.
The string/floating ball don't pull upwards since the forces they create don't matter outside of the context of the beaker. It'd be like trying to lift an object that you're standing on in order to fly. Or making a giant floating balloon and trying to use it to move the earth.
Because it'd be obvious to anybody who isn't a mentally deficient ESL
They do though.
The tension of the string matters and cancels out a chunk of the added weight by water displacement. That's why left is lighter than right.
Both have same displacement, but the strings shows an upward force being applied. It's not a solid string, there is tension, hence why it's not exactly part of the same system.
Hope that helps understand the problem user.
Which is shocking coming from you user. Dont confuse the other user if you don't know the answer next time. Thank you!
>it'll increase the weight on the scale.
Maybe as you put your foot it and you're exerting force downward but once you stop moving and just hold your foot there floating in the water it'll go back to being the weight of the water and the bucket since your leg is supporting your foot. If you went limp and let your leg float in the water then it would add weight like you're saying but I can't imagine a bucket large enough to do that without cheating and touching the sides, in which case it would be obvious that you're adding weight to it.
Those are two opposing forces that cancel one another out. In the example, the right side goes down because the steel ball itself weighs down on the water.
Your foot will not do the same thing assuming you maintain consistent tension.
The tension in the string is equal to the buoyant force acting on the ping pong ball; they cancel out.
?
That's just not how archimedes principle work.
If you were to hold your leg in a bucket, no limp, the volume of your leg, in water density, would be still added.
Water displacement adding weight is a thing, really.
That's what i said. Hence the right side weighting more.
>Weight of ping pong + weight of glass of water = weight of glass of water
>retarded
>for not knowing how string tension impacts the system
This is a pretty obscure physics interaction which is basically irrelevant to everyone in the thread. Spendingtime to learn this is actually the retarded choice.
The weight of the ping-pong is really negligible user
It's good to see the string and acknowledge there is an unaccounted force there, which points out the right side tipping answer.
All puzzles are pointless if you don't learn from them
Ok, I think I got it. The displacement increases the pressure around it except up where the water can freely move.
Thank you, user.
Ping pong ball is floating, but the string holds it down. The buoyancy of the ping pong ball perfectly counters the added weight and tension of the string, creating a net neutral effect.
The weight of the steel ball is exerted on the stand and not the beaker. Thus, only water displacement is present in the scale, rendering the two balanced.
Video games.
Basically, yeah.
Also, even holding your foot with your leg, your foot would weight less. Water is pushing up, and all displaced water is pushing down.
Final point is this: with the foot, or the steel ball, the added weight is not measured directly by grams, but by the volumed it has displaced. That volume, in water, is added.
Im happy to talk user, thank you for reading. Give Archimedes principle on wiki a read, is a good thing to have in mind
Right is heavy though.
Heavier*
The steel ball's weight is exerted upon the stand and not the scale, because the steel ball is not physically connected to the beaker or the scale. Some of the water sits on top of the steel ball, weighing it down, rather than the ball weighing the water down.
>get this question in a second year engineering exam
>skip it
good luck faggots
Yes I understand displacement.
But you said both are balanced. They're not. Right is heavier.
There is displacement in both but the string cancels it out in left. Right, then, is heavier
It literally doesn't impact the entire system, you retard.
If the system in question is the amount of energy transfer within the cup of water, then yes the string matters, because the string is under an amount of tension, but that tension is being dispersed into the cup.
Zoom out once and relative to the scale though, the string and the ball are simply factors within the cup with both of their mass adding to the total of the cup.
Consider a hot air balloon that is tied to the earth but floating in the air. Does that hot air balloon pull the planet upwards in space?
No it doesn't, because thats retarded.
Consider all the variables and which systems they belong to, anons.
>Right is heavier
>displacement is cancelled by string
String weight cancels out the ping pong balls' buoyancy, not its displacement. It adds more to the displacement effect, identical to the steel ball's string.
The two beakers are the same weight.
>Does that hot air balloon pull the planet upwards in space?
It does though. That's the amount of tension on the anchoring rope
They are not. Right one is heavier BECAUSE of the string. Without string (let's say with a little stick making the ping-pong ball submerged) they'd be balanced.
You're getting the string tension wrong. The right one is heavier, really.
Im only replying to you this once, because that is such an unbelievably stupid thing to say that you've gotta be fucking with me at this point.
The upward force gets dispersed into the ground you dope. Sure you could add enough hot air to increase the tension enough so that you pull up the ground below the anchor a tiny bit, but then you've suddenly removed the balloon AND the string AND that bit of earth from the system, so earth B with the helicopter flying above the north pole now weighs more.
Now that's actually incorrect.
If a stick was pressing the ping pong ball into the beaker, even if it perfectly pushed it down, would actually apply additional force to the left beaker and while not making it heavier, this outside force would cause it to imbalance the whole system.
>Right one is heavier BECAUSE of the string
Now you're just being retarded. If the ping pong ball was not present, the string would make the left beaker heavier as it lays in the beaker. The string's weight is fully cancelled by the buoyant ping pong ball (assumed to be a perfect balance because picture example.)
Thus, it's like the ball and the string aren't there except for liquid displacement.
There is 0 weight exerted on the right beaker by the ball or the string, thus its weight is unchanged, balancing with the left.
The only flaw in that image is the visual of the strings now having the same length submerged, but in an actual experiment, this would be adjusted properly.
>The upward force gets dispersed into the ground
Yeah, that's the earth.
I'm not talking about moving the earth, I'm talking about a force being applied.
I'm sorry user but you got it very wrong, and your example reveals it. It's not too late to learn though.
OH NO NO NO NO
>Now you're just being retarded
No user. The right one is heavier. I can explain it to you in any level you choose to, but name calling is a bit off.
You don't understand tension and you think that the physical dimensions/weight of the string matter. They don't.
Right is heavier because it doesn't have the tension out of buoyancy like left has. Left displacement ia being cancel out, hence, lighter.
So you want me to draw you the forces? I can. (I'm not fucking with you or insulting you. Just explain why you're wrong)
What in the fuck are you even saying.
You ARE talking about moving the earth im my example, you just don't get it, the earth is equal to the left side of the scale relative to the topic at hand because the "force being applied" is being applied in order to lift the left side of the scale.
Is your shitposting loop so shittily written that it has already broken down and forgotten what its arguing?
Or am i just being le epic trolled
>There is 0 weight exerted on the right beaker by the ball or the string, thus its weight is unchanged, balancing with the left.
user, you know that the archimedes principle is a thing. Don't you?
Do you want me to explain why what you said is wrong?
Neither because portals aren’t real

Underrated desu senpai
I don't get it.
If you want to remain ignorant, by all means. I just replied to your hot balloon example where you said that thr balloon applied no force to earth. That is wrong.
The ping-pong ball (through the string's tension) does the same, applying force to the beaker.
Right side is heavier.
Side note: you seem very angry and worries about trolls. You shouldn't care about that. I'm genuinely trying to teach you something because you're missing key things in your physics conception.
A
Kinetic force ends where the platform stops.
The speed of the portal doesn't translate in cube speed.
It's A I think.
That's an entirely drawn out image to just say "it can't be either".
iirc portals despawn if the wall its on moves in the portal engine
explanation is nice though
It applies force to the beaker but the beaker then disperses the force, otherwise either the string or the beaker would break.
So if you fill the beakers on a balance with the EXACT same amount of water, and one of the beakers on the scale has a mass of beaker+500.ml water+string+ball, and the other has a mass of beaker+500.ml water, you believe that those two things have the same amount of mass on this earth?
For op's pic to work there would have to be a very very tiny amount more water in the right beaker.
Deal with it
Energy in=energy out
Mass in=mass out
Ask me if I'm mad
All valid, but you're creating an absolute point of reference.
The portal moving towards the cube or the cube moving towards the portal is the same thing in relation to the blue portal/context.
Therefore, B.
Because they both weigh the same as your mom: so much that the scale breaks, so it counts as zero.
The water tries to push the ball on the right up and ends up pushing itself down.
Right one is heavier though.
The mass of the string and the weight (outside water) of the ping pong are irrelevant. The steel weight outside water is irrelevant also.
Only relevant parts: same beakers, same water, same ball volumes, same water displacement (and since archimedes principle, same added weight).
Up until now, all is same, and if you had a tiny stick pushing down the ping-pong ball, it would be balanced.
But! String! The left string is having tension. Why? The ping pong ball's density is applying force to the string in the exact inverse way as the weight of the water displaced.
Right: displaced water added force
Left: displaced water added force minus string tension.
Right is heavier. This is a fact user, there is experimentation.
I hope i help you understand. I really do.
my point is that the portal would despawn and the wall would crush the cube
I agree by in-game logic. Just replying to the actual answer of the problem outside game logic.
Holy fuck you're a moron. The buoyancy only affects the ball itself, not the entire system. Do you seriously think the ping-pong ball is somehow magically pulling the rest of the jar up? Christ you're a fucking dipshit.
Not the jar, but it does cancels out the water displacement. Which is enough to make it lighter in comparison to the right side.
Why are you so angry about this?
One, celluloid is denser than water, so it's adding an infinitesimal amount of weight to the left beaker. Two water temperature variance can cause density of water to fluctuate just enough to offput the scale like this.
It doesn't just displace it, it does add weight. Celluloid (ping pong ball) is denser than water. It then must weigh more than the opposing glass assuming both balls are displacing the same amount of water, and the water in both is approximately equal in temperature.
The displacement from the left is cancel out by the different density of the ping-pong, while is not on the right.
Temperature and the actual weight of the ping-pong ball are irrelevant
I've always said this and everyone acts like I'm a fucking idiot. Take that for what you will.
It is, the right side is just adding more since the water is keeping the ball submerged, taking some force from the string. At least I think from what I gather itt.
Ping pong ball is adding weight, just slightly less from buoyancy.
cringe
Wait what?
I'm taking physics 2 next term so this shit is gold, thanks user. Maybe this puzzle will be talked about in class even.
This would definitely be A since there is no force being applied to the box (besides gravity at the end since the box is teleported to an incline at a completely different orientation.
Imagine an open doorway in front of the box. Now imagine if you moved this doorway over it. Nothing would happen since they wouldn't touch and thus no force is applied. The same thing is happening here. The box goes through the doorway (portal) and is repositioned compared to gravity, but it wouldn't shoot out.
Imagine metal bars blocking the entrance of the blue portal, now imagine the platform slamming down on the cube. What happens to the metal bars?
