(a)

Interpretation Introduction

Interpretation:

The given number has to be rewritten in the form of number (±absolute uncertainty)

Concept Introduction:

Uncertainty:

Uncertainty means state of not certain in predicting a value.  In a measured value, the last digit will have associated uncertainty. Uncertainty has two values, absolute uncertainty and relative uncertainty.

Absolute uncertainty:

Expressed the marginal value associated with a measurement

Relative uncertainty:

Compares the size of absolute uncertainty with the size of its associated measurement

Relative uncertainty = absolute uncertaintymagnitude of measurement

Percent relative uncertainty:

Percent relative uncertainty = 100 × relative uncertainty

To Rewrite: The given number in the form of number (±absolute uncertainty)
