but it has air holes, else they would die. if they died it would be 1.5kg

how dense are those fucking flies? are they made of gold? The solution is break the jar and keep the flies.

how much does the lid weigh, is it counted as part of the jar? I would say 1kg. The flies are suspended in air therefore don't impact the scale. Also did you reset the scale to 0 after placing the vessel on it?

[Anonymous No.54606024]

>>54605877
it feels like there are some concepts involved here we don't have unless we were previously educated in physics in which case the answer would be evident. I don't know for instance if the closed lid with the flies counts as weight because somehow they affect the atmosphere contained inside the jar or not

[Anonymous No.54606042]

Assuming a closed system with no exterior forces, and that the flies are not accelerating (including falling), the scale would read 1.5 kg. Only vertical vectors of force need to be considered and the center of mass of all objects is above the scale. The vertical force on the flies to stop them from falling would be transfered in an equal and opposite force against the scale. In reality, the flies would likely be in motion and the scale would change as they accelerated up and down.

[Anonymous No.54606044]

>>54605961
Not if the jar is sealed. The flies must exert force of 0.5kg downwards to stay afloat so I would say 1.5kg.

it depends if there's a lid
with lid 1.5kg assuming lid weighs 0.00
without lid 1kg, maybe just slightly more due to airstream

scale reads 1 kg if flies are flying, 1,5 kg if flies are not flying. basic physics, retard. did you even finish high school? go back to /r9k/ and cry about it.

[Anonymous No.54606203]

>>54605877
None of the above, it'd be between 1 kg and 1.5 kg depending on a variety of considerations, but mostly close to 1.5 kg.

This a riddle too many anons will unfortunately fall for.

The answer's obvious, even with room temperature IQ. The flies lift the jar in the air, cancelling out .5kg of the jar's weight per fly. In simple mathematics:

X = jar weight
Y = fly weight
Z = true weight

Counting the image in the OP, we have 5 flies. This means:

X - (Y*5) = Z
1kg - (.5kg*5) = Z
1kg - 2.5kg = Z
Z = -1.5kg

As illustrated, this would mean the weight on the jar would dip into the negatives, effectively making it weightless. Because the flies have no sense of self or consciousness, outside the desire to flock towards dung, we can assume they would forcibly crash into the nearest ceiling. The force generated from the crash would kill the flies on impact, dropping the jar back down to the scale.

With the now dead flies, we can reverse the value of Z and turn it into a positive. The final weight of the jar is as follows:

Z = -(-1.5kg)
Z = 1.5kg

1.5kg is the undisputable answer. Any other answer is simply incorrect and misguided.

it doesn't say "fly weights" or "flies weigh", it says "flies weighs" which I assume is the total weight of the flies.

assuming they're flying, 1kg. if they put you in a jar and you could float, your weight wouldn't register on a scale underneath it. if you jump on your scale does the weight show up while you're in the air or when you land. 1kg ez, next thread

1.5, unless you tared out the weight of the jar first.

[Anonymous No.54606798]

The disturbed air would disrupt the reading on any good scale rendering it null and void. OP is the idiot for letting flys into a controlled environment.
The correct answer is: N/A

The flies are exerting negative pressure to stay afloat so 0.5kg is what the scale reads.

[Anonymous No.54607956]

>>54605877
The down force created by flight overcomes gravity making the jar weigh 1kg while the flies are flying. When the flies land however, their weight is added the jar's.

[Anonymous No.54608357]

>>54606622
floating involves downward force on the medium the object is floating on. you wouldnt say an olive weighs nothing if it was floating in a martini.

the flies would exert a force equal to their weight for every downward thrust of their wings.
if the flies weigh .5kg, they would add a fluctuating weight of +.5kg to the jar depending on their apogee in the flight cycle

[Anonymous No.54608944]

>>54605877
1kg if you didn’t tare the scale first with the jar otherwise 0kg.

[Anonymous No.54609077]

Without trolling, does the jar actually contain the weight if the flies are in the air? Because they aren't pressing on the scale, how can they ever be of any weight? Or is it because they are contained in the jar they get added to the weight of the jar?

I have no idea how to try this otherwise I would have checked myself. Maybe a balloon in a box

Guys, there was a mythbuster episode of trucker with a container full of chickens crossing a bridge. His truck weighed a bit too much, so he rustled the container so the chickens would stay afloat in the container, making it weigh less.
Myth was busted.

Nothing, because scales can't read

[Anonymous No.54610901]

Assuming the flies are airborne, they don't 'push directly down' to stay airborne. From an insect's perspective, air is a lot thicker, so flying for them is a bit like swimming for us. Air is a fluid, so think of it as a very thin fluid.
Their wings are pushing against the air that they are in contact with, which creates tiny whorls and eddies in the airflow which does create some downward pressure directly under the fly but as long as they're all far enough from the bottom of the jar it shouldn't affect the number on the scale significantly.

[Anonymous No.54610947]

those are some chonky ass flys, my dude.

[Anonymous No.54610956]

based on heisenberg's uncertainty principle, the jar is both there and broken. The flies are also dead and alive. When you observe the jar it causes wave function collapse and the superposition of states will resolve to one state based on your current world line.

tl;dr op is a huge nigger and it's 1 KG
