what are bergmann's and allen's rules?
446622
Bergmann's rule states that organisms at higher latitudes should be larger and thicker than those closer to the equator to better conserve heat, and Allen's rule states that they will have shorter and thicker limbs at higher latitudes.

The simple mathematical relation is friction factor = (4 times coefficient of friction). This relation is very useful in solving problems in gate, csir net, etc. One more useful relation is coefficient of friction is (64/Re), where Re is Reynolds's number for laminar flow.

When assigning electrons to orbitals, we must follow a set of three rules: the Aufbau Principle, the Pauli-Exclusion Principle, and Hund's Rule.

The aufbau principle, from the German Aufbauprinzip (building-up principle), also called the aufbau rule, states that in the ground state of an atom or ion, electrons fill atomic orbitals of the lowest available energy levels before occupying higher levels.

The Octet Rule. The octet rule refers to the tendency of atoms to prefer to have eight electrons in the valence shell. When atoms have fewer than eight electrons, they tend to react and form more stable compounds.
