I (Now) Understood function of G in those equations. We use Formula/Equations to derive other Formulae/Equations and which (to my knowledge) are either definitions, or laws or derived from other equations. I wanted to know if Einstein used any form of Newton's law of gravitation to derive his...

Here:

I am sorry for writing that line but how can a response like the first one from this thread help a high school student? I am here to learn. If it cannot be understood in simple terms. Okay! I'll quit. If question was not clearly stated let me clarify it. Everyone knows 'Everything is done in...

I forgot the source but I heard above quoted line more than once probably in YouTube videos. Is it common misconception about gravitation? I just wanted to know, whether any reference of Newton's gravitational law is taken during derivation of that equation or Einstein found that it is the...

I don't know complex mathematics about general theory of relativity but i tried to understand it from internet. Somewhere i heard that in GTR gravity is explained as curvature of space-time not as force as in Newton's laws. If GTR doesn't explains gravity as force then why G which is constant of...

I know all these. I think I was unable to state the problem clearly. but I found this on stackexchange, going to read the paper that answerer mentioned. THANK YOU!!! https://physics.stackexchange.com/questions/357284/force-on-a-current-carrying-conductor-and-hall-effect

Okay, now I have electrostatic force to attract fixed ions. This force is internal force. Isn't it? Can internal force produce external acceleration to move wire as a whole.

Your reply does not clearly answer my question. I always thought Lorentz force experienced by electrons inside the conductor as internal force. If their position is not fixed inside the conductor then how can they move conductor? Instead they are going to move towards one side, strike the...

A current carrying conductor experiences magnetic force in a magnetic field. F=BILsinθ Where, B = Magnetic flux density I = Current L = Length of conductor and θ = Angle between magnetic field and current This force is due to free electrons moving in a...

No they don't or maybe, I didn't understand well. "Magnetic field lines are defined as hypothetical closed curves through which a free unit magnetic northpole would move in the magnetic field." I don't think this definition gives any idea about how many lines can be drawn in a particular region...

Magnetic flux density(B) is defined as, magnetic force per unit pole strength and flux is defined as magnetic field passing normally through given surface. I think, I am clear about these definitions, and quantitative meaning they carry. I usually find, in some texts, the definitions as in image...

But my interest is not on how a theoritical black body works, i am interested to know can radiation from a heated object be explained sililarly as in the case of atomic spectra(electronic transition)?

My book says that emission spectra are produced when an electron in excited state jump from excited to lower energy states. It also states that solids and liquids produce continuous spectra and it depends upon temperature only (is this black body radiation?). I know, Electrons around a nucleus...
