Question # 1

Explain " Rounding off numbers ?

  • Ans 1: The quantities in a measurement are always rounded off to certain level of accuracy. The following rules must be observed while rounding off a number.
    1. If the dropping digits is less than "5" then the last retained digit is kept as it is For example 863.73 is rounded to 863.7
    2. If the dropping digits is greater than '5' then the last retained digits is increased by '1' for example 9.66 is rounded to 9.7
    3. If the dropping digits is '5' and the last retained digit is even then it will be remain uneffected. For example 66.45 is rounded to 66.4
    4. If the dropping is '5' and the last retained digit is add, then it will be increases by '1' for example 76.35 is rounded to 76.4

Question # 1

Are radius and steradian the basic units of SI? Justify your answer?

  • Ans 1: Radian and steradians are not the basic units of SI. These are the units of purely geometrical quantities i,e plane angle and solid angle respectively. The general conference on weight and measures has not yet classified there units under either base unit or derived units these are called supplementary units.

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
