A physical question.
There is a floating cubic-formed matter in water. Half of it inside
and the other half outside of water.
1) If we translate it to the moon, haw amount of it will be
inside water?
2) What about, when the same matter is on a planet with gravity
twofold of earth.
3) What is the situation to water at zero gravity?
(Suppose all other conditions as it in the earth.)

Hi, Ramin1102000
Answer:
1)still half.
gravity of the matter=floating force
so, density of matter= 0.5 *density of water
i.e. p=0.5p0
when you transport it to the moon, only the gravity accleration
change and other physical properties won't change. So still half in
water and half outside.
2) still half. You only change the gravity field but you will not
change the mass or density of the matter.
3)when it's at zero gravity, no pressure inside water since the
pressure inside water is caused by the gravity of water. So in that
situation water and the matter just float in the space and there is
no force applied between water and the matter.
Why you ask these questions?

Hi Pkuyzh,
You say, on effect of each gravity except zero gravity, half of the
matter is floating inside water. Well! Now can tell what is the
minimum amount of gravity besides zero gravity, which will cause the
matter, be floating inside the water (half inside, other half
outside)?

Hi, ramin1102000
Yes. That's my answer and I talked with a professor in physics
department. And he areed with me. At this point, I only couldn't know
what will happen between finite gravity field and zero gravity field.
He told me that if other conditions won't change the only difference
is when you move the cubic stuff. In finite case, when you move it
because of the gravity the cubic stuff will always
go to the static state, but if it's zero gravity water and stuff just
go away and cannot go back to the original state. So, if you have
further question feel free to post here.

Hi Pkuyzh,
Doesn't it become easier when we accept this; it'll be change the
amount of swallowing down
Water for cubic stuff with change of gravity acceleration?
Ramin

................
Hey, ramin1102000
Well, for me yours is not acceptable because it's not going to follow
the basic law in physics.Based on the physical law, it's not going to
change with change of gravity acceleration(in the case that all other
conditions won't change). I don't know what's the purpose for you to
propose this question. So if you want to solve something by thinking
in the way you believe, could you tell me what's your problem?
Thanks.

Hi Pkuyzh,
Do you amen that's: "Human-made laws"? But the nature operates
without any attention to human-made laws. Have you any evidence for
your opinion in the nature?
Ramin
......................................................................
..................
Hey, ramin
I am not saying that's "human-made laws".Which law can explain the
physical phenomena correctly and give the right predictions which law
is right!
Now, let me tell you to do an experiment to test my answer for your
question.
You prepare things you mentioned in your question and enter an
elevator and start it. look at the matter in the water to see if it's
going down or stay the same level. (Elevator is a good place to
simulate change of gravity).
Still the old sentence I want to say, human being has very smart
brain but also has bias. You need to look at the data and physical
evidence to varify your thought.
......................................................................
...................
Hi Pkuyzh;
Yea, when elevator starts to go up or go down, or when plane lands or
when it rises, passengers feel vertigo, and if the variation of
acceleration be considerable, it causes nausea in them. When becomes
empty under your feet, you must feel falling inside yourself to save
yourself. There is an organ named cochlea in inner ear which creates
this feeling. There is a liquid full inside it and there are things
floating in it. So it influences (changes of gravity) on floating
matters.
You said in 97 issue: I only couldn't know what will happen between
finite gravity field and zero gravity field. Can you describe this
finite gravity (which you mentioned)and determine it's amount?
Ramin
......................................................................

hi,
The matter will not move if you don't give it a small disturbation.
When you give it a small disturbation, because the gravity change and
the force to keep it settling down is decreasing. So it will take
longer time or the amplitude of the movement will increase. That's
why your body doesn't get used to it. But the final stage is the
matter will keep the original status if you give it long enough time.

Hi,
If someone has understand your message 106 in this club explain it
for me too, please.
Ramin

I understood.
math
...............................................
Hi math_earth,
Well, so you describe this finite gravity (which Pkuyzh mentioned)
and determine it's amount. Please.
Ramin
........................................
Hi,
I'm waiting for your answers.
Ramin
...........................................
seems no one is answering. I Don't know what finite gravity would be.
is it infinitesimal gravity that you can feel but you cannot feel?
just kidding.
cliff_sd
........................................
The gravity is increasing.
It's increasing, causes to more swallow of things which are floating
on water. It influences marine animals, they make resistance against
swallowing in depth of sea everytime by using new organs to
lightening themselves.
This is a fact.
Ramin
...................................
But also there are other reasons which can explain why sea animals
went to shallower depth instead of going down. For example, the
percentage of oxygen, the temperature change and so on. The
relationship between gravity increase and the biological observation
you got is not very staightforward. Sometime even data seems to have
some kind of correlation but based on the nature, ther don't have any
relationship.

Read this article. If no satisfied, invite Mr. william sarjeant to
the club to say his opennes on these articles. He has read one issue
of my book.

William sarjeant was born in shefield, 1935. He graduated withhonors
in geology from the shefield university in 1945 and recieved his ph.d
from the same institution in 1959. Sarjeant taught geology at the
university of Nottingham from 1963 to 1972 and then Immigrated to
canada, where he has infiliated the Department of geological scineces
at the university of saskatchewan since 1972. He has also published
175 paper and a seires of 10 volume books on the history of geology.
He has recieved several honors among them are sue Tyler friedman
Medal from Geological society of london in 1990. Founders medal from

Hi, Ramin
I don't know if the gravity field of the earth increased or not. I
don't have any evidence to either supporting it or against it. What I
know is that if we keep other conditions and only change the gravity
field the floating stuff won't change its status based on the
Newton's Laws.
This is my final statement about this discussion.
Pkuyzh
...............................................
Hi,
Most of Newton's movment rules, modified by scientists after him.
Perhaps, his this rule, needs to be reformed too.
Any way:
Would you like to have a discussion together with on an other topic?
Ramin

Hi, Ramin,
what do you think about Einstein's general theory of relativity?
cilff_sd
....................................
I am agree with Einstein, That :
In high speeds, energy changes to mass, and mass of matter increases,
and I believe that this is one of the reasons for increasing mass of
the earth. We can observe this increase of mass as melted articles
which comes out from volcanos and splits of oceans.
Ramin
......................................
Ramin,
Have you really tried to understand what Einstein(the greatest
physicist) told us by his brilliant theories? What you said seems far
away from his theories. You probably want to attend a physics club to
get correct physical concepts .
only suggestions
math_earth
....................................
I think this club should change it's name to "introduction to
science" or "correct your wrong concepts"
math_earth
..................................
Einstein says:
In high speeds, when we want to more increase the velocity of a
matter by entering a force, a major amount of this force changes to
mass. When the velocity of the matter is near to the velocity of the
light, whole of the involved force, changes to mass.
Ramin
.................................
Getting exact sentence doesn't mean getting exact meaning. The high
speed is for semi-light speed. Even though not the same as light
speed, it's very close to the light speed.
Please go back to see what you said for the magma example. It's
ridiculous. Everyone know that oceanic lithosphere subducing into the
mantle and during the subduction process some part of lithosphere
melt and rise up to the surface as magma. Do you the rotation speed
of earth can be counted as mass?
//faint
math_earth
...............................
Ramin's statement-- "this increase of mass as melted articles which
comes out from volcanos and splits of oceans. " is totally false.
My point was that in order to argue for a point about paleogravity we
also need to keep an eye on the general theory of relativity.
discussions are always welcome!
silff_sd
.................................
The speed of rotation of the earth can't increase mass of the earth,
of course. My mean is the velocity which is so close to the velocity
of light. That's the velocity of going out of sight of galaxies from
eachother. Our galaxy goes out of sight with a velocity close to the
velocity of light, as compared with very far galaxies (The theorem of
extension of the world) and as the earth being in this galaxy, so
it's moving with a velocity close to velocity of light together with
galaxy, too. But about that theorem which you've been mentioned about
coming out of magma, it wouldn't be able to state the energy resource
which is required to such a movement, up to now.
Ramin
..................................
After so many "interesting" discussion. Here is a website which is
really related to geophysics.
"Geophysics is amazing and beautiful".
Pkuyzh
................................
Expanding universe theory:
Galaxies are going out of sight eachtime from eachother. The speed of
going out of sight of galaxies from eachother is higher, they be as
far from eachother. If two galaxies were too far from eachother, they
are going out of sight from eachother with a velocity close to the
velocity of light.
Steady state theory:
New galaxies are being created in remained blench spaces, by keeping
out of the way from eachother and growing old. The energy which stars
are radiating from themselves, are raw materials which new stars are
creating from them.
Continuous creation:
Parallel to expanding universe, the creation of material is realized
till, the average density be
steady.In other to establishing such status, material is being
created mitt a rate about 10(-43)kg/m3 per second.
The theory of gravity increase of the earth:
The earth, being a part of this universe, can increase it's mass
getting energy from it's around. The conclusion of this increase, is
magma, which comes out from Volcnos and split of oceans' bottom, and
causes the motion of continents. Beside of increase mass, the gravity
of earth increases too and this increase of gravity causes biological
changes and getting species of plants and animals smaller or extinct
big species.
