Significant Figures in Measurement
The number of significant figures in a measurement is crucial as it indicates the precision of the measurement. Significant figures are all the digits in a number that are known with certainty plus one uncertain digit.
Explanation of the Correct Option
- Option D, 2.6008 cm, has 5 significant figures because all the digits are known with certainty.
- The first three digits (2.600) are the measured value, and the last two digits (0.08) are uncertain and considered significant.
- Therefore, the number of significant figures in option D is 5.
Comparison with Other Options
- Option A, 26.08 mm, has 4 significant figures as the last digit (8) is uncertain.
- Option B, 0.02608 m, has 4 significant figures as the leading zeros are not significant.
- Option C, 2.608 cm, has 4 significant figures as the last digit (8) is uncertain.
Conclusion
In measurements, it is essential to consider the number of significant figures to convey the precision of the value accurately. Option D, 2.6008 cm, stands out in this case with 5 significant figures, indicating a higher level of precision compared to the other options.
