(1 Point)​

Answer 1

assertion is correct but reason is wrong

Answer 2

The assertion is correct but the reason is wrong is considered as a significant figure

Explanation:

• All of the certain digits in a measurement, plus one uncertain or estimated digit, make up the important numbers.
• The instrument's precision is determined by the significant digits; for example, if a value is read as 1.8 m on a scale, the reading can be 1.83 on a more exact instrument.
• Accuracy is the degree to which a measured value is close to the real value, regardless of the measuring device used.
