and you will measure a different mass when submerged.
You will measure a different weight, but the mass is still the same.
Mass is the same as weight
Quote from: Bored chemist on 04/12/2017 18:33:36You will measure a different weight, but the mass is still the same.Kg is a measure used on a set of scales is not? Mass is the same as weight which is Newtons of force.The mass is not the same it would measure less kg so stop lying.
In physics, buoyancy ( /ˈbɔɪ.ənsi, -əntsi/[1][2] or /ˈbuːjənsi, -jəntsi/;[1][2]) or upthrust, is an upward force exerted by a fluid that opposes the weight of an immersed object.
ravity is not acting on the plastic corn in this situation.
The buoyancy force
So what is the buoyancy force on a Quantum level of understanding?
In modern science:- the effects of large things that produce significant gravitational fields are best described by General Relativity (these things are too big to display quantum effects).- the effects of small things that produce nuclear fields are best described by Quantum Theory (these things are too small to display gravitational effects)- We don't (yet) have a theory that unites the two domains.In-between, we have the familiar human-scale world where things don't produce much of a gravitational field, or display much quantum effects, but they are able to respond to external strong gravitational fields (eg the Earth's gravitational field).So I think that it is pointless to describe the behavior of the float on your fishing line using either General Relativity or Quantum Theory. As BC says, use Classical physics.I would apply the Thermodynamic principle which says that "Over time, things tend to approach the state of lowest energy".- Water is denser than the float- So in the Earth's gravitational field, the system is in a lower energy state if the water is on the bottom, and the float is on the top ... compared to the condition where the float is on the bottom, and the water is on the top- So, on the Earth's surface, the state where the water is on the bottom, and the float is on the top is much more likely, over time- In the ISS, where the acceleration due to Earth's gravitational field is cancelled by the ISS orbit, the two states have equal energy, and either state is equally likely.

Since he doesn't understand the difference between mass and force, I suspect that trying to do thermodynamics isn't going to go well.

There are things called molecules.
Do you realise it's because the water is pushing back up?

Please tell me about the ISS, does it have a geostationary orbit where it moves with the earth rather than around the earth?
geostationary orbit
Lots of little things make one big thing, a big thing is still little things , all things have fields regardless of the size. 1+1=22 is greater than 1 so everything about 2 should be twice as much as one. I don't see the problem of unification. A big thing is a little thing at distance.
