This is an interesting situation.
You have said "low friction ice". We think what you're saying is that the ice is
doing nothing but holding them up, but nobody can get any traction with their
boots to pull against. The only way they can pull on the rope is with their arms.
So they might as well be two people, facing each other at opposite ends of a rope,
in outer space. We can't help visualizing it that way.
Everything starts with both people motionless and no slack in the rope, and then
the referee tosses the flag. (He can't just drop it because it won't go anywhere.)
If either person pulls on the rope, two things can happen: Either the other person
lets it go completely, or the other person holds onto it tight.
-- If the other person lets the rope go completely, then there's no way to get any tension
in the rope, and the person that's pulling winds up with a bunch of rope in his face.
-- The other person holds tight to the rope so that the rope develops tension in it:
It seems to us that whenever there's tension in the rope, whether both people are
pulling or one of them is just holding tight, the force of the end of the rope against
each person is going to wind up equal, and they'll accelerate equally toward each other.
Well, maybe not equally ... the skinny will accelerate toward the center faster than
the fatty does. F=M A, the force at each end is equal MfatAfat = MthinAthin, and the
accelerations are inversely proportional to their masses.
Athin = Afat (Mfat / Mthin) = 4 times the acceleration of the fatty.
We also think that since the whole thing was initially motionless, there's nothing
that either person can do to move their center of mass from where it was when
they began. The isolated system composed of two people and a rope began with
no momentum, so the whole isolated system never gets any, no matter what they do.
As long as both of them hold the ends of the rope, the point on the rope where their
center of mass is never moves anywhere.
Their accelerations are equal and they each slide 6 meters before they meet.
A layman's attempt: Any unbalanced force applied over time to an object that is free to move will bring about acceleration.
If an attempt is made to sell you a magnetic generator, on the claim that it will supply you with free energy, then that attempt constitutes a scam ... that is, an attempt to defraud you for the seller's benefit. If the magnetic generator is simply demonstrated, with no attempt to persuade you to do anything about it, then it's simply a magic show ... that is, an entertaining illusion. In either case, you must understand, even if it's not obvious to you, that the magnetic generator is not doing what the operator may claim it is doing, or what it may appear to be doing.
We don't know why it is that light is a constant and everything else is relative. Our understanding does not reach there. And we can't go faster than light because of the "conversion" of the energy of acceleration. It acts in a way that requires continually more energy be applied in an attempt to push an object closer to the speed of light. The more energy we apply, the more "resistance" to acceleration we'll encounter. And we cannot ever push the object to the light speed threshold. It is a real "barrier" in that sense.As regards time moving backwards, that is a speculative concept. If time slows down for an accelerated frame (for someone moving really, really fast), it might "stop" and "move backward" as the frame moves to and through c's barrier. (The speed of light is often seen designated by c.) It might be possible to move back in time, but we don't know if this is possible. We have no physical way to test it now, and one is not on the horizon. However Einstein said that it takes an infinite amount of energy to achieve light speed and there is no such thing, see theory of relativity for more info
No, but the result of our attempt to understand gravity and describe it is.
Bernoullis principle says that as a liquid's flow rate increases the pressure of the fluid decreases (think of your thumb on a garden hose) When air ( fluid) flows over a wingsurface the shape of the wing directs the air to travel a greater distance, and its speed is decreased. The pressure difference below the wing (higher) relative to the pressure above the wing (lower pressure) creates lift as high pressure areas move to low pressure areas in an attempt to restore equilibrium

Relative age of the rocks and the Paleo environment.
Relative inequality relates to absolute poverty because both people will attempt to change their situation. They may also have the similar feelings for people who are rich.
Its relative to your style of bowling, speed, curve and the pins left on the lane for your second throw.
John Dalton tried to work out the relative masses of atoms; but his calculations were wrong, although the principle was correct. He was, however, the first to establish a table of atomic masses with hydrogen, the lightest atom, as the standard.
The mathematical technique used to calculate the area under a graph is integral calculus. This is a complex subject which I am not going to attempt to explain in detail- it normally takes years of study.
Scientists who study physics are called physicists, and they study and discover the rules by which the universe functions. They create and study Scientific Laws that attempt to mathematically explain speed, velocity, acceleration, time, electromagnetism, light, gravity, etc..
Nothing. They say 'Pass Away' in an attempt to tell scared children if their relative passed away to make it seem less bad. But death isn't scary, though. :)

One may fit indoor shutters for their windows in a variety of ways; such as following the user manual often provided with the provided shutters. If this is not applicable, attempt to ask a relative or contact a professional.
1) the Czech defenses were very strong 2) the German generals, conscious of Germany's relative weakness at that moment, were actually prepared to attempt to remove Hitler had he continued to move forward.
Maps that attempt to represent the Earth don't do a good job because the scale is normally wrong. Continents are not drawn based on their actual size relative to others.
