Question

student a says: \it is impossible to get a perfectly exact measurement because every measuring device is limited in how many decimal places it can measure accurately.\ student b says: \if i had better equipment i would be able to make accurate measurements.\ student c says: \you would be able to make accurate measurements if you knew how to do it properly. let me do it.\ who is right? justify your answer.

Explanation:

In measurement, all measuring devices have a limit on the number of decimal places (precision) they can measure. Even with the best equipment or proper technique, there's inherent uncertainty (e.g., due to instrument resolution, physical constraints) that prevents perfectly exact measurements. Better equipment or technique can improve precision/accuracy but not eliminate the fundamental limit of exactness.

Answer:

Student A is right.
