Solution
A coherent derived unit is defined as a derived unit that, for a given system of quantities and for a chosen set of baseunits, is a product of powers of baseunits with no other proportionality factor than one
The principle of homogeneity is that the dimensions of each the terms of a dimensiional equation on both sides are the same . Any equation or formula involving dimensions (like mass, length, time , temperature electricity) have the terms with samedimensions.
supplementary units. (physics) Dimensionless unitsthat are used along with base units to form derived units in the International System; this class contains only two, purely geometrical units: the radian and the steradian.
