Question
Write the correct techniques for measuring length accurately. Explain why are they important?
✓
Answer
Correct techniques for measuring length include placing the scale in contact with the object, aligning the scale properly along the object’s length, and positioning the eye directly above the measurement mark to avoid parallax errors.
$\rightarrow $ These techniques are important to ensure accuracy and consistency in measurements.
$\rightarrow $ For example, measuring a pencil with a broken scale requires starting from a full mark and subtracting the initial reading to obtain the correct length.
