    • Zeros to the left of significant figures are not significant .
    • In decimal fraction, zeros to the right of a significant figure are significant.
    However , in integers, the number of significant zeros is determined by the accuracy of the measuring instrument.
    • In scientific notation, the digits other than the powers of ten are significant.

Question # 1

How can we reduce random and systematic error?

  • Ans 1: Reduce random error: Repeating the measurement several times and taking an average can reduce the effect of random error.

    Reduce systematic error: The systematic error can be reduced by comparing the instrument with another which is known to be more accurate and a correction factor is applied.

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

Question # 1

Discuss the conventions for using SI units?

  • Ans 1: The various conventions for using SI are given below.
    1. Full name of the unit does not begin with a capital letter even if named after a scientist.
    2. symbol of unit name after scientist has initial capital latter for for example N for newton Pa for pascal H3 for hertz etc
    3. The prefixes is written before an adjacent to the unit
    4. The combination of units is written each with one space a part For example , Torque =55 N m
    5. Double, triple etc prefixes are not allowed
    6. When a multiple of base unit is raised to a power. The power applies to the whole multiple and not just the base unit
    7. Before substituting values in the formula to calculate the final result make sure that all the included physical quantities are expressed in their SI 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
    • Supplementary Units
