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

Write down four conventions for indicating units.

Ans 1: The convection for indicating units are as follows:
1. Full name of the unit does not begin with the capital letter even if named after a scientist e.g. Newton.
2. The symbol of unit named after a scientists has initial capital letter e.g. N for newton.
3. The prefix should be written before the unit without any spacee.g. 1x 10^-6= µ m
4. Compound prefixes are not allowed. For example 1 µµF should be written as 1 pF.
