Significant Figures

Significant figures are important in scientific calculations as they represent the accuracy of the measurements made. The number of significant figures in a measurement or calculation is based on the least precise measurement or calculation involved.

(i) 10.2cm + 8cm = 18.2cm

- Both 10.2cm and 8cm have one significant figure.
- Therefore, the answer should have one significant figure.
- The correct answer is 18cm.

(ii) 2.53m - 1.2m = 1.33m

- Both 2.53m and 1.2m have two significant figures.
- Therefore, the answer should have two significant figures.
- The correct answer is 1.3m.

(iii) 4.2m * 1.4m = 5.88m^2

- Both 4.2m and 1.4m have two significant figures.
- When multiplying, the number of significant figures in the answer is equal to the sum of the significant figures in each number used in the multiplication.
- Therefore, the answer should have three significant figures.
- The correct answer is 5.88m^2.

(iv) 3.6m / 1.75 * s = 2.1m * s^-1

- 3.6m has two significant figures, 1.75 has three significant figures, and 2.1 has two significant figures.
- When dividing, the number of significant figures in the answer is equal to the number of significant figures in the least precise number used in the division.
- Therefore, the answer should have two significant figures.
- The correct answer is 2.1m * s^-1.

Answer: (ii) and (iv) only.
