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

Explain dimension of physics quantities ?

  • Ans 1: The power to which the fundamental units of first system must be raised to give the unit of a physics quantities are called dimensions of that quantity
    Explanation:The dimension represents the nature of a physics quantity. It tells us that how a quantities is related to the base units .It is represented by capital letters in a square brackets For example
    1. Dimension of mass length time are respectively written as [M] , [L]
    Use of dimensions.
    1. The dimension are used for checking the correctness of an equation or formula
    2. The dimension are used for deriving of certain formula for a physics quantity.

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
