is the percentage uncertainty in a ruler 0.1cm? yes or no? i think yes..
To determine the percentage uncertainty in a ruler, we need to know the absolute uncertainty or the smallest measurement that can be reliably obtained with the ruler. If the ruler has a smallest division of 0.1 cm, we can consider this as the absolute uncertainty.
The percentage uncertainty is calculated by dividing the absolute uncertainty by the measured value and then multiplying by 100.
However, you have only provided the absolute uncertainty (0.1 cm) and not the measured value. Without the measured value, we cannot calculate the percentage uncertainty. Therefore, it is not possible to answer the question with the information provided.
To determine the percentage uncertainty, you would need to measure a specific length using the ruler and then calculate the percentage uncertainty using the formula mentioned earlier.
