Question

How are the numerical value (n) and unit (u) of a physical quantity related? (1) n  u (2) n  1 u (3) n  u 2 (4) n  2 1 u​

Answer 1

Answer:

For example length, mass, time, force etc. ... Thus in expressing a physical quantity we choose a unit and then find that how many times that unit is contained in the given physical quantity, i.e. Physical quantity (Q) = Magnitude × Unit = n × u. Where, n represents the numerical value and u represents the unit.
