Question

Count how many significant figures there are in each of the following measured values:

A) 5
B) 4
C) 6
D) 3

Answer 1

Significant figures are

A) 1

B) 1

C) 1

D) 1

Step-by-step explanation:

Significant figures represent the digits in a measured value that are considered reliable or certain. In this case, each measured value provided (5, 4, 6, 3) contains only one digit. As per the rules of significant figures, any non-zero digit is considered significant. Therefore, each of the given values has only one significant figure.

The concept of significant figures is crucial in scientific measurements, indicating the precision or certainty of a measured value. In these cases, since the values are integers without any decimal points, each digit is considered significant.

Understanding significant figures is essential in scientific calculations and expressing the precision of measurements. It helps in indicating the reliability and accuracy of measured values in scientific experiments and calculations.
