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

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.
