Answer 1

Explanation:

1.001 wI'll be more Accurate

Answer 2

Answer:

The correct option is b) 1.01 m.

Explanation:

• We should assess the level of uncertainty an instrument adds to the data obtained when it is utilised in a lab.
• Assuming that each instrument has been calibrated against a recognised standard is ideal.
• The systemic errors are minimised if this is the case.
• Precision relates to the reproducibility of a measurement, whereas accuracy indicates the idea of the right response or actual value (recognised value) for a certain physical quantity.
• The degree of accuracy indicates how closely the experiment's outcome matches the actual value.
• As a result, it serves as a gauge for how accurate the outcome is.
• Without considering whether the result agrees with the true value, an experiment's precision is a measurement of how well the result has been determined.

The metre stick can measure up to the accuracy of 1cm or 0.01 m.
