Question # 1

Define system of units ? Give the name of various system of unit?

  • Ans 1: System Units:A complete set of unit for all physical quantities is known as system of units .
    Explanation:There are several system of unit For example
    Foot - pound - system ( FPS)
    Meter - kilogram -second system (MKS )
    Centimetre - gram - second system (CGS )
    But the most popular system id the system international (SI)
    System International(SI):In 1960 on international committee agreed on a set of definitions and standards to describe the physical quantities. The system that was established is called system international (SI)
    The system international is used throughout the world. Its unit are convenient for daily use .
    The system international is build-up from three kinds of unit
    • Base Unit
    • Derived Units
    • Supplementary Units

Question # 1

What is Scientific Notation .Explain ?

  • Ans 1: Writting number in power of ten or standard from N=M*10nis called scientific Notation.
    Explanation:With the help of Scientific Notation, we can express very large number or small number very easily. A large or small number "N" can be expressed in term of a number "M" and a power of '10 '
    N= M * 10n-------------------(1)
    In equation 1 "M" represents a number whose first digit is non-zero digit. "n" represents the power of 10, which may be positive or negative
    For example 150,000,000,000 m can be expressed in scientific notation as under
    150,000,000,000 m = 1.5* 1011m
