What is the actual flow of electrons in a wire? ...How? ..Will the shape of wire be changed?

Dr Annamalai.

Electrons flow quite slowly through electrical wires - it's a common undergraduate experiment to measure this flow speed. The mean drift speeds is of the order of mm/s in common metals. The flow of these particles does not alter the shape of the wire.

What is the difference between gravitation and gravity?

Gravitation is the attractive force between any two planets. Gravity is the force that pulls objects (within the Earth and its Atmosphere) toward the center of the Earth. Am I right?

Einstein's mass-energy equivalence is just one value for the velocity in kinetic energy equation. Am i right?

E = (mv^2)/2 is the kinetic energy equation. Here, sqrt(2) * c = 423970560 m/s, where c = 299792458 m/s is speed of the light in vacuum. E = (m*[sqrt(2) * c]^2)/2 = mc^2. ER=m*(423970560 m/s)^2,...

Anything that has mass also has gravity. Is it true?

Anything that has mass also has gravity. Objects with more mass have more gravity. Gravity also gets weaker with distance. So, the closer objects are to each other, the stronger their...

In the Universe, all the objects (except running in vacuum) are orbiting other object(s)or moving in a circular path. Why?

I think these phenomena follow the scientific facts defined in the classical mechanics, but not theories or definitions in Einstein's mechanics.

Why doesn't chromium 2+ ion use all its d-orbitals to receive lone pairs from six waters in [Cr(H20)6)]3+?

I'm guessing it's because the ligand experiences too much electron repulsion or proton repulsion from the chromium to insert them close to the 3d-orbitals which are close to the metal nucleus. Is...
