10. john has an electronic balance that always measures objects 2 kg less than their actual mass. how would you describe the balance?\n\ta. precise and accurate\n\tb. precise but not accurate\n\tc. not precise but accurate\n\td. neither precise nor accurate
Answer
Brief Explanations:
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
