Answer:
2, 3
1.01, 1
Percentage uncertainty
Step-by-step explanation:
a) The significant figures in the number 99 is 2
The significant figures in the number 100 is 3
b) Uncertainty in each of the numbers for both the numbers is 1
Percentage uncertainty
99
[tex]\text{Percentage uncertainty}=\frac{\text{Uncertainty}}{Value}\times 100 \\\Rightarrow \text{Percentage uncertainty}=\frac{1}{99}\times 100=1.01[/tex]
Percentage uncertainty = 1.01
100
[tex]\text{Percentage uncertainty}=\frac{\text{Uncertainty}}{Value}\times 100 \\\Rightarrow \text{Percentage uncertainty}=\frac{1}{100}\times 100=1[/tex]
Percentage uncertainty = 1
c) Percentage uncertainty is a better way to express the numbers as the significant figures do not show the actual value of the numbers.
