Question

dimensional analysis is a problem - solving technique used for ______.

○ writing scientific notation

○ converting units

○ assigning graph axes

○ determining graph formats

Explanation:

Dimensional analysis is a method that uses the dimensions (units) of physical quantities to convert between different units. Writing scientific notation is about expressing numbers in a specific form, assigning graph axes is about choosing variables for axes, and determining graph formats is about the type of graph (like bar, line). So dimensional analysis is used for converting units.

Answer:

B. converting units
