Final answer:
To calculate percentage error, you need to find the absolute value of the difference between the measured value and the accepted value, divide it by the accepted value, and then multiply by 100.
Step-by-step explanation:
To calculate percentage error, you need to find the absolute value of the difference between the measured value and the accepted value, divide it by the accepted value, and then multiply by 100. In this case, the measured value is 94.5 cm and there is no accepted value given. Therefore, it is not possible to calculate the percentage error for this measurement without knowing the accepted value. Therefore, none of the provided options (a) 0.53%, b) 0.58%, c) 0.63%, d) 0.68%) are correct.
