i want to specifically focus on the mechanism inside an atom . suppose there are some electrons in the nth shell of the atom. They reduce the effective nuclear attraction on the electrons in the (n+1)th shell. can we say that the vector fields of the n shell electrons and the nucleus superimpose...

If we approach this problem based on classical physics viewpoints, a body can be at rest v = 0 .that is the minimum velocity possible w.r.t any reference frame whatsoever, assuming of course that by 'minimum velocity' you're referring to the magnitude. otherwise , the -ve sign dosen't create a...

that again will be decided by time, as to whether we will be equipped soon enough with all necessary equipment for leaving. its not that we just need to pack our suitcases with a lot of shirts and trousers and a toothbrush and just hop onto a bus :P . anyway , i think we're going off course , so...

i think we can let time decide the rest can't we? :)

we have already stated the fact that ASSUMING WE GET THAT AMOUNT OF HYDROGEN . other than that, the rest is not impossible is it ?

i believe that the trick lies in realising the fact that the net external force acting on the rocket is now, no longer the reaction due to its own engines, but also gravity acts on it. so we need to modify the LHS first

#PWiz i don't think its completely hypothetical , if we can manage that amount of hydrogen, because , if we consider the fact that Jupiter's huge mass produces an enormous gravitational field. the hydrogen gas we pump in there , should remain there due to this gravity , as hydrogen atoms will...

if i am correct then , yes , the constant of integration is there to fix that. i haven't checked your calculations as they look fine. c is supposed to be (ve * ln(mo ). if you evaluate the definite integral of the function between t = 0 and t = ti (for any ti) then you'll see that the velocity...

energy is a function of state of any system. When there is a change in state of the system, its energy changes. We attribute this change in energy to a physical quantity---force. Force is much easier to understand obviously, but in harder problems, it gets too tedious to work with vector...

I guess that the obvious phenomenon is , in mathematical terms, the superposition of the scalar potential fields, whose gradients give us the forces(in this case gravitational). The fact that the forces follow superposition principle is a mere result of the fact that their fields are...

I am rather a beginner to this field .So please forgive me if this is a very meaningless question. QUESTION: If I were to somehow increase Jupiter's mass by adding more hydrogen to its atmosphere, can i ever reach the stage where the mass of the planet becomes enough to undergo gravitational...
