To determine the number of significant figures in a measurement, you need to consider the known digits and the estimated digit. Here's how you can determine the number of significant figures in each of the following measurements:
1. 8.65 - This measurement has three significant figures. All the digits (8, 6, and 5) are known and contribute to the precision of the measurement.
2. 0.0032 - This measurement has two significant figures. The zeros after the decimal point are significant in this case. Both the digits (3 and 2) are known and contribute to the precision.
3. 4.008 - This measurement has four significant figures. The leading zeros before the digits (4, 0, and 0) are not significant when they are used only to specify the position of the decimal point. However, the zeros between two significant digits (4 and 8) are significant.
4. 5000 - This measurement has one significant figure. The zeros in this case are considered placeholders and do not contribute to the precision of the measurement. If the number ends with zeros and there is no decimal point, it is assumed that those zeros are placeholders.
5. 120.00 - This measurement has five significant figures. All the digits (1, 2, 0, 0, and 0) are known and contribute to the precision of the measurement. The zeros at the end of the number and after the decimal point are significant.
