comment How can randomness exist?
"if the universe were to somehow be recreated with PRECISELY the same properties, down to the smallest level possible," It's not safe to assume this is possible in principle. Even in the deterministic Bohmian Mechanics, there is an inescapable uncertainty of the actual configuration of beables.

comment how can we apply the formula p=VI in power transmission lines?
I recommend that you try asking your questions here: electronics.stackexchange.com Primarily due to the fact that there is a built in schematic editor that will greatly aid in asking and answering questions of this type.

comment Theory on what would happen if a proton touches anouther
You do know that a proton is a system, right? It seems to me that you're picturing a proton as two charged billard balls with smooth surfaces and such. At any rate, the first thing you would have to do is to clarify, in scientifically meaningful terms precisely what you mean by "two protons touched each other". While you're at it, define what tricking space or a proton means.

comment How can light have the same speed for all observers?
It's not a bad thing to be confused at first by this since, essentially, everyone is initially confused by this. However, this very well might be the most frequently asked question of all the frequently asked questions about special relativity. In other words, please take the time to do just a bit more research on this most frequently asked question.

comment Relation between the conservation of Energy and the conservation of Momentum?
Honestly, it can't be said much clearer than this: A perfectly elastic collision is defined as one in which there is no loss of kinetic energy in the collision. An inelastic collision is one in which part of the kinetic energy is changed to some other form of energy in the collision. hyperphysics.phy-astr.gsu.edu/hbase/elacol.html Since this collision is inelastic, one cannot assume the KE before and after are equal.

comment Tension in a pulley system
@Swapnil, your assumptions (or drawings) are incorrect. Consider again what I wrote in my previous comment and also, take a look at the Wikipedia article on tension: en.wikipedia.org/wiki/Tension_%28physics%29: "In physics, tension describes the pulling force exerted by each end of a string, cable, chain, or similar one-dimensional continuous object,"

comment Tension in a pulley system
"then I don't understand what happens at midpoint of rope?" - if the rope is static (unmoving, unaccelerating), then the net force at any point in the rope must be zero. Pick a point, the midpoint for example, on the rope and draw the forces on it; they are equal and opposing forces (otherwise the point would accelerate). However, at the ends of the rope, you and the rigid support must supply the opposing forces. Does this help?

comment Why does a conservative force return the work done against it by a body to that body?
@user36790, can you describe what you mean by 'agent of conservative force'. Unless we're both clear on what you mean by that, we won't make any progress.

comment Tension in a pulley system
"So the first question: How can the tension be UPWARDS at BOTH sides of the pulley?" This is a puzzling question because I can't imagine how you could think it would be otherwise. Both masses are being pulled downward by gravity which means that each end of the wire is being pulled acting to stretch (lengthen) the wire. It seems intuitive that the wire would resist this by 'pulling up'. You wouldn't expect the wire to push down on the masses would you? If the wire were horizontal and being pulled at both ends, wouldn't the wire 'pull back' at both ends?
