Question # 1

What do you mean by significant figures ? Give the rules for determining significant figures ?

Ans 1: Significant Figures:The combination of accurately known digits and the first doubtful digits during a measurement are known as as significant figures
Rules for determining significant figures:
1. All non-zero digits from '1' to '9' are significant for example in 36.473 m there are five significant figure
2. All zero between two non-zero digits are significant for example in y= 4.03 m there are three significant figures
3. The zero to the right of a decimal symbol and to the left of non-zero digits are not significant
4. All zero to the right of a decimal appears after non-zero digits are significant
5. In case of scientific notation the figures before the power of ten are significant
6. In case of addition and subtraction the result obtained is retained to the measurement which is least precise in the data
7. In case of multiplication and division the final result is retained to the measurement which contains the last number of significant figure
8. In case of rounding of non-significant figures the following rules should be followed.
- IF the dropping digits is less than '5' then it will be just ignored For example 863.73 is rounded to 863.7
- If the dropping digits is greater than '5' then the last retained digit is increased by '1' for example 8.76 is rounded of 8.8
- If the dropping digits is '5' and the last retained digits is even then it will remains uneffected. for example, 56.45 is rounded to 56.4
- If the dropping digits is '5' and the last retained and the last retained digits is add than it will be increased by '1' for example 46.35 is rounded to 46.4

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.
