Step-by-step explanation:





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

Percentage uncertainty = 1.01
100

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.
Answer:
4.19
Step-by-step explanation:
just use the formula 2pir^2
The equation is:
[e^x] [e^(2x)] = 4
1) Applying property of multiplication of powers wiith same base =>
e ^ (x + 2x) = 4
=> e ^ (3x) = 4
2) Applying logarigth properties
3x = ln(4)
=> x = ln(4) / 3 ≈ 1.38629 / 3 ≈ 0.4621
Answer: x = ln(4) / 3 ≈ 0.4621
Answer:
100
