Answer 1

Explanation:

11) It is the act of unifying the different laws valid for different phenomena in to a single theory that explains all the different phenomena. ... These are unified under theory of electromagnetism; Reduction: It is the effort to solve a complex problem by breaking it into simpler parts.

12) Fundamental quantity : quantities which are independent on other physical quantity . ex: length,mass,time, current, amount of substance, luminous intensity, thermodynamic temperature, Derived quantity : quantities which are depend on fundamental quantities.

13) units are standards for measurement of physical quantities that need clear definitions to be useful. Reproducibility of experimental results is central to the scientific method. A standard system of units facilitates this.

14) The units and their physical quantities are the second for time, the metre for measurement of length, the kilogram for mass, the ampere for electric current, the kelvin for temperature, the mole for amount of substance, and the candela for luminous intensity
