Correct option is A
Explanation:
A
diagonal scale is specifically designed to measure up to three different units or dimensions, such as
meters, decimeters, and centimeters. It allows for precise readings by enabling measurements of units, their sub-units, and further subdivisions.
·
Primary Divisions: Represent the main unit (e.g., meters).
·
Secondary Divisions: Divide the primary units into smaller units (e.g., decimeters).
·
Diagonals: Allow for the measurement of even smaller subdivisions (e.g., centimeters).
The diagonal scale achieves this by using a set of equally spaced horizontal lines (representing secondary divisions) intersected by diagonal lines. This arrangement helps interpolate between the smallest divisions on the scale, enabling accurate measurement of the third unit.
Therefore, on a
diagonal scale, it is possible to measure three dimensions:
1.
Meters (Primary Unit)
2.
Decimeters (Secondary Unit)
3.
Centimeters (Tertiary Unit via Diagonals)
