What is the limit of reading and absolute error as a fraction for a table measured as 102.0 cm?

Here are the solutions to your problems.

Question 1:
The length of a table measured with a ruler calibrated in cm is 102.0 cm.

• A. The limit of reading of a ruler: The measurement 102.0 cm is given to one decimal place. This implies that the smallest division on the ruler is 0.1 cm.

  $$\text{Limit of reading} = \boxed{0.1 \text{ cm}}$$

• B. The absolute error as a fraction: The absolute error (uncertainty) for a measurement like 102.0 cm is typically taken as the smallest division, which is 0.1 cm. The
