Is there any formula for calculating the no of images formed by two mirrors at an angle say α. If yes,then please guide me to a proof of the same.

The mass of wall is infinite So momentum can be finite with even zero velocity as mathematically, infinite multiplied by zero can be something(finite value)

That is only the case for water due to anomalous behavior. Yes there a change in density from liquid to gas change while there is little from solid to liquid.

Why is the latent heat of vaporisation greater than that of fusion(melting)? I mean in liquid state,atoms are already far apart, so it must require less energy to make them gas(far apart) as forces(electric in nature) between molecules decrease with distance.

So how do identify easily that a molecule or atom is diamagnetic or paramagnetic or ferromagnetic?

Centrifugal force acts away the center(frugal meaning to flee) while centripetal force acts towards the center(petel means to seek). Centrifugal force is simply a pseudo force due to use of non inertial frame of reference

Can the specific heat capacity be negative? Is there any substance for which i have to add heat to decrease its temperature? By the way,why specific heat capacity has the word "capacity" in it? Is there any physical significance to it or it is simply traditional(historical)?

The wall has gained momentum(but notice it has no velocity as mass of wall is infinite) the conservation of momentum applies to systems where there is no external force applied. if you only consider the ball as system,the wall applies a force on it during collision. But with ball and wall...

But then even steady current moving in curved path is same as electrons moving in synchrotons.the electrons do radiate so why doesn't the current(which is simply flow of electrons)? I am totally confused here?

In fact,ALuminium is a paramagnetic material(as outermost electron is unpaired), so the induced magnetic field in aluminium is low(order 0f 10^-5 of the external field) so aluminium IS attracted towards a magnet,but very weakly practically if you had a strong magnet aluminium will be...

Current is simply flow of charge, and acceleration of charged particles produces EM radiation. Then if we bend a wire,charges(current) would be accelerated as they change direction,then a bent wire must radiate.Is it true?

But for neutrons can we say Newton's laws will be fully applicable??

But even then how can statistics change the nature of force,how can it change something that is the way of working of force.

I was talking about rate of cooling with respect to time.

What is the cause for diamagnetism and other types of magnetism? Is it related to Farady's law or quantum mechanical properties of matter?
