Answers
Given : In S.I. system, there is one unit for one physical quantity
To Find : So system is called
(a) coherent
(b) metric
(c) rational
(d) closely related to cgs system
Solution:
In S.I. system, there is one unit for one physical quantity so system is called
coherent
coherent means logical and clear without any ambiguity
option (a) coherent is correct
It comprises a coherent system of units of measurement starting with seven base units and 22 Derived units ( coherent)
Every physical quantity has exactly one coherent SI unit, although this unit may be expressible in different forms by using some of the special names and symbols
second (the unit of time with the symbol s),
metre (length, m),
kilogram (mass, kg), ( it is an exception having k with gram )
ampere (electric current, A),
kelvin (thermodynamic temperature, K),
mole (amount of substance, mol), and
candela (luminous intensity, cd).
SI - abbreviated from the French Système international (d'unités)
International System of Units
This is metric System of units
it is a unified and rational system of measures
it can be related to cgs system by conversion.
The system allows for an unlimited number of additional units,
called derived units, which can always be represented as products of powers of the base units
In S.I. system, there is one unit for one physical quantity. So system is called (a) coherent
