comment Conservation of energy in vertical circular motion
The centripetal force does no work because it always acts along the radius vector and the length of the radius vector never changes.

comment Will Buoyant Force Change If The Container is Accelerated Up or Down?
@Freelancer: this would apply to horizontal acceleration as well. See for example Why does a helium filled ballon move forward in a car when the car is accelerating?.

comment Can this Temperature Scale be Considered an absolute temperature scale?
@prakharlondhe: correct - there is no restriction on the absolute temperature scale to be non linear

comment Can this Temperature Scale be Considered an absolute temperature scale?
The Dalton scale is a temperature scale in the sense that you can consistently measure temperatures with it. But you would have to be barking mad to actually attempt to use the Dalton scale in thermodynamic calculations.

comment Can this Temperature Scale be Considered an absolute temperature scale?
The Kelvin scale is linear in the sense that for an ideal gas the internal energy is proportional to the temperature. So each extra degree K adds the same increment of internal energy. If you want your Namu scale $T_N$ to preserve this linearity then it needs to be related to the Kelvin scale $T_K$ by $T_N = aT_K + b$ where $a$ and $b$ are constants. I'm guessing this is what you mean by your expression mK + c. If you're not fussed about the linearity then you could use a more general scale, but all your equations will get more complicated if you do.

comment Why is power dissipated in a circuit maximum when external resistance is equal to the internal resistance in the circuit?
Current is a maximum when $R_\text{ext}=0$ not when $R_\text{ext}=R_\text{int}$.

@prakharlondhe: Yes, your Namu scale is a perfectly good absolute temperature scale.

comment Interpretation of time dilation
Hi Mason. I think Alfred and Jon are being a bit unkind, because most of your answer is just fine and you correctly pull out the key point that the proper time along a photon trajectory is always zero (this is true in general relativity as well). However I agree that the sentence So, that means that if you travel at the speed of light, you observe no time passing! is meaningless and you should edit it out.

comment Why is power dissipated in a circuit maximum when external resistance is equal to the internal resistance in the circuit?
I suspect the book means that the maximum power dissipated in the load $R$ is when $R=3$. If you set $R=0$ then the power dissipated in $R$ is obviously zero, and if you set $R=\infty$ the power dissipated in $R$ is obviously zero. So the maximum of the power dissipated in $R$ is somewhere in between. With a bit of algebra you can easily show the maximum is at $R=3$.

comment Why neutrinos are weakly interacting?
Hi Muthu, we encourage new users to search the site to check if there question, or one very like it, has been asked before. In this case the obvious search quickly finds the duplicate I've suggested.

comment can we quantize a static electron-magnetic vector potential which is time-independent?
Real photons can only be emitted by accelerating charges but virtual photons do not have this restriction. A time independant electromagnetic field can be described by QED just like any other electromagnetic field.

comment Cherenkov radiation can it happen in a jar using tap water with 8 thorium laced lantern mantles as a radiation source
I would guess the Cherenkov radiation is there but it's too faint to be seen. The blue glow seen in pictures of nuclear storage pools comes from very intense radiation many orders of magnitude higher than your thorium mantles can produce.

comment Shapes in a black hole
The definition of space does not change. The spatial coordinates are defined in exactly the same way inside the horizons as outside them.

comment Shapes in a black hole
I'm afraid that last comment makes no sense. By shape I assume you mean some surface in two of the space like dimensions e.g. a spherical or cubic surface. Assuming this shape can resist tidal forces it won't change shape on crossing either of the horizons.
