@omvaykul0 if u expand and write u will observe that the equality is satisfied for all x=a1,a2,......an hence we found more than
n1 roots for a n1degree polynomial so it's a identity and has infinite roots

@NishantThakre !
So lower integral sum<Integral<upper integral sum 
RE: com
@NishantThakre we cannot do that...we don't know the magnitude of internal forces....but we can write impulse equation and find magnitude of that minimum common velocity

@Kshitijpal
It's from hydrogen discharge tube....so I found the transition in hydrogen which is closest to my energy constraint so that photoelectrons emiited from energy lower than that will also stop

@NishantThakre ...I don't know the mathematical proof.... the theory behind it is which I told you....

RE: Fluid mechanics
@HarishR i have just used normal formula of kinetic energy for ice........for water I first found the velocity of water by differentiating the eqn of conservation of mass of water ....and then used it. And total mass of moving water in normal formula of KE

RE: Ionic Equilibrium
@omvaykul0 .....as we go on adding NaBr......the dissociation of AgCl goes in forward direcn and the Ag+ reacts with Br to form ppt ...now we wanted 75% AgCl to ppt as AgBr.....so no of moles of Cl become 0.1×0.75=0.075
