Answer 1

Given:

The image of the ruler which measures length in inches is given.

To find:

A. The smallest increment on the ruler.

B. The uncertainty

Explanation:

A)

From the ruler, we observe that,

There are 4division s between any 2 consecutive whole numbers

So, the smallest increment on the rule is,

$\frac{1}{4}=0.25$

Final answer:

The smallest increment on the ruler is 0.25.

B)

The formula for the uncertainty is,

$\begin{gathered} \Delta x=\frac{The\text{ smallest increment}}{2} \\ =\frac{0.25}{2} \\ =0.125 \end{gathered}$

Final answer:

The uncertainty is 0.125.
