the value indicated by the arrow on the cm ruler is __1__. the number of significant figures is __2__. the uncertainty is __3__. a. 1.7 cm b. 1.07 cm c. 1.1 cm d. 0 e. 1 f. 2 g. 3 h. 4 i. +/- 0.1 cm j. +/- 1 cm k. +/- 10 cm l. +/- 0.01 cm m. +/- 0.001 cm
Answer
Explanation:
Step1: Read the ruler value
The arrow is between 1.0 cm and 1.1 cm, closer to 1.1 cm, so the value is 1.1 cm.
Step2: Determine significant figures
Non - zero digits are always significant. So 1.1 has 2 significant figures.
Step3: Find uncertainty
The smallest division on the ruler is 0.1 cm, so the uncertainty is +/- 0.1 cm.
Answer:
- C. 1.1 cm
- F. 2
- I. +/- 0.1 cm
