A generator or a battery is used for the conversion of energy from one form to another. Examples include ionic NaCl and K2O and covalent networks such as SiO2 and C as diamond or graphiteIonic compounds do not exist as individual molecules. A formula unit in chemistry is the empirical formula of any ionic or covalent network solid compound used as an independent entity for stoichiometric calculations.
It is related to the concept of an empirical formula which is the simplest chemical formula expression for a non-ionic chemical compound.
M - 2 or Pascal-seconds Pa s Hence the coefficient of viscosity is a measure of the resistance of the fluid to deformation at a given rate due to internal friction. EMF is the commonly used acronym for electromotive force. So Poissons Ratio is dimensionless.
