Answer :
Final answer:
a) Spring balance
A spring balance may measure mass inaccurately due to human error, as it typically does not measure as precisely as digital scales do.
Explanation:
The type of measuring tool used in science that measures mass inaccurately due to human error is a) Spring balance. While other balances, such as digital scales, are more precise and can measure masses to the nearest thousandth of a gram, a spring balance might provide more room for human error as it typically measures mass only to the nearest 0.1 g. Human error can occur when interpreting the scale of the spring balance, as it is not as direct or definitive as reading a digital display.
Measurement uncertainty in such devices arises from a combination of the measurer's skill and the quality of the measuring tool. Other tools like the triple beam balance, beam balance, and graduated cylinder can also be sources of error if not used correctly, but a spring balance, being mechanical in nature, typically presents a higher degree of uncertainty.
