If Pascal is related to pressure, in the same way Newton is related to ____.
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → Force
The pair is a unit and the quantity it measures. The pascal (Pa) is the SI unit of pressure, one newton per square metre. In the same way the newton (N) is the SI unit of force: the force that gives a mass of 1 kg an acceleration of 1 m/s2.
Why the other options are incorrect
Option (1) Density — Incorrect. Density is mass per unit volume, measured in kilograms per cubic metre (kg/m3).
Option (2) Volume — Incorrect. Volume is the space an object takes up, measured in cubic metres (m3).
Option (3) Time — Incorrect. The SI unit of time is the second (s).
