- Significant Figures: Significant figures in the measured value of a physical quantity tell the number of digits in which we have confidence.
- The larger the number of significant figures obtained in a measurement, the greater is the accuracy of the measurement and vice-versa.
- Significant figures do not change if we measure a physical quantity in different units.
- Significant figures retained after the mathematical operation (like addition, subtraction, multiplication, and division) should be equal to the minimum significant figures involved in any physical quantity in the given operation.
- Significant figures are the number of digits up to which we are sure about their accuracy.
EXPLANATION:
- Trailing zeros or the zeros placed to the right of the number is significant.
- Therefore, 433.00 has five significant figures. So option 4 is correct.
