Chapter 1, Problem 1.1P

(a)

Interpretation Introduction

Interpretation:

The SI units of length, mass, time, electric current, temperature and amount of substance have to be listed and abbreviation has to be written for each SI unit.

Concept Introduction:

SI units refers to ‘International System of Units’ which have been used in the modern scientific calculations and metric system.

It constitutes units of measurement of seven basic parameters – length, mass, time, electricity, temperature, amount of substance and luminous intensity.

The SI unit of measurement must be written as symbol in lowercase but unit named after a scientist must be written with first alphabet as uppercase.

Interpretation Introduction

Interpretation:

Units and symbols for frequency, force, pressure, energy and power have to be written.

Concept Introduction:

SI units refers to ‘International System of Units’ which have been used in the modern scientific calculations and metric system.

It constitutes units of measurement of seven basic parameters – length, mass, time, electricity, temperature, amount of substance and luminous intensity.

The units derived from the seven fundamental units that are stated above are termed as SI derived units.

The SI unit of measurement and derived SI units must be written as symbol in lowercase but unit named after a scientist must be written with first alphabet as uppercase.
