I would gracefully decline this. Define a dead system. You would see what I mean. Life is chemistry, and when some critical functionalities stop in the brain, we call it brain dead or dead for short. That is the only definition of dead. As a result of micro state change - the macro state of...

There are some issues for Doppler Shift on matter waves. The wavelength is given by :- \lambda = \frac{h}{p} where p is the momentum. The phase velocity of the wave is:- v_p = \frac{C^2}{v} where v is the velocity of the particle. The wave is super luminal. There are more fun to it...

Photons has momentum! Photons has momentum! Common misconception is that, as it has momentum, it must be having a mass. That is untrue, as we know that any wave has a momentum!

There is a probability and that too is 100% is that, the Guy who said it is MAAD. :eek: People, without appropriate context should not talk like that. In the mean time the picture you drew is a waste, as that shifting never happens in the solids. Any kind of solids. :devil: Ok...

Position does not makes sense in case of a Gas. It makes sense sometimes in the context of a drunk person. Think it from that perspective. Cheers. BTW, if the box is 1 KM, sir, then again we have certainly more disorder to achieve...remember the diffusion? That is the phenomenon.

There is nothing called a pure Covalent..compound. Nothing is purely covalent. Only the molecules are. Think of HCl as:-- H-Cl, with Cl having the bonding electron cloud closer to it. In water, the picture is that due to fact that H^+ + Cl^- is of low energy, so it is stable in the...

There are many ways! 1. By POMI: proove it for n = 2, and assume for n=k and show it holds for n=k+1 also. :smile: 2. Use z=r*exp[i{theta}]. So, 2cos{theta} = r*exp[i{theta}] + r*exp[-i{theta}] So, we can see that Re[r*exp[i{theta}] + r*exp[-i{theta}]] = 2cos{theta} So, that...

Apply the derived equation for the Weak Acid and strong base...I guess there is one dervied from that, applying the fact that the HCN will be very less ionized, whereas the NaCN will go and create a strong base thing...NaOH

Read J.D.Lee, elementary questions, pal. Viloating the Rules I guess, but I will answer. So Acid are something with donatable H+, which means accepting e-! That is exactly Lewis Acid, anything that accepts e- is an Acid. Anything that donates e- is Base...

At the boiling point we still have the liquid as well as have the gas/vapour. So we have 2 different state of the same object. Naturally then the rules we apply for the liquid applies at that point to...which means, the liquid still has a surface tension, but it is reduced. It does not drops...

No ...force means sum of all forces... No this is not the case. The net force on one electron must be balanced by the another. Get the concepts back again. In a system with no *external* force, the total momentum must remain conserved. And, study more conservation laws. There is never a...

It's easy! Ok, put it this way:-- Have a magnetic field and a charge running with a velocity v. Now run parallely to the charge...you see that the charge is still bending without any force! That is the *vilolation* of every law, unless you know from a moving-ref-frame the E field certainly...

I guess if W is the work then that is the Energy, and Power is really is synonym for dW/dt = P the power. So that is that. By the way W = Integral_over_time[Power] !

Draw some picture, instead of talking...can not understand the problem and the solution you are posing...

1st thing first...DO NOT USE AN ADMINSTRATIVE A/C to work commonly. 1st thing first...DO NOT USE AN ADMINSTRATIVE A/C to work commonly. That is it. NO Virus can spread unless they are super-user, or Admin. That is the idea. So connect to net when you are an ordinary user, and that is it! :!)
