Question

1. john has an electronic balance that always measures objects 2 kg less than their actual mass. how would you describe the balance?

\ta. precise and accurate
\tb. precise but not accurate
\tc. not precise but accurate
\td. neither precise nor accurate

Explanation:

Precision refers to the consistency of measurements. Since the balance always measures 2 kg less, it is consistent in its error, so it is precise. Accuracy is about how close the measurement is to the true value. As it always measures 2 kg less, it is not accurate.

Answer:

B. Precise but not accurate
