Consider two lengths are measured by a ruler i-e L1=10.0cm and L2=20.0...
**Understanding Accuracy and Precision:**
Before we analyze the accuracy and precision of the measured lengths, let's first understand the concepts of accuracy and precision:
- **Accuracy:** Accuracy refers to how close a measured value is to the true or accepted value. In other words, it measures the correctness of a measurement.
- **Precision:** Precision refers to the consistency or repeatability of a set of measured values. It measures the exactness or reliability of a measurement.
**Analyzing the Given Measurements:**
L1 = 10.0 cm and L2 = 20.0 cm
**Accuracy:**
To determine the accuracy, we need to compare the measured values with the true value. However, in this case, we don't have any information about the true value of the lengths. Hence, we cannot determine the accuracy of the measurements.
**Precision:**
To determine the precision, we need to consider the consistency and repeatability of the measurements.
- L1 = 10.0 cm: This measurement has one decimal place, indicating that the ruler used has markings up to that level of precision. Hence, we can say that L1 is measured more precisely.
- L2 = 20.0 cm: This measurement also has one decimal place, indicating the ruler used has markings up to that level of precision. Hence, we can say that L2 is also measured precisely.
Since both measurements have the same level of precision, we can conclude that both L1 and L2 are equally precise.
**Summary:**
Based on the analysis, we can conclude the following:
a) Accuracy: We cannot determine the accuracy of the measurements as we don't have the true value.
b) Precision: Both L1 and L2 are equally precise as they have the same level of precision (one decimal place).
Therefore, the correct answer is: c) more precise.
