Question:

If Pascal is related to pressure, in the same way Newton is related to ____.

Options:

Density

Volume

Time

Force

Correct Answer:

Force

Explanation:

The correct answer is Option (4) → Force

The correct answer is Force.

Explanation of the Relationship

This is an analogy based on SI units (International System of Units). In physics, every physical quantity has a standard unit of measurement.

  • Pascal (Pa): This is the SI unit of Pressure. One Pascal is defined as one Newton per square meter ($1\text{ Pa} = 1\text{ N/m}^2$).
  • Newton (N): This is the SI unit of Force. It is defined as the amount of force required to accelerate a mass of one kilogram at a rate of one meter per second squared ($1\text{ N} = 1\text{ kg}\cdot\text{m/s}^2$).

Why the other options are incorrect:

  • Density: The SI unit for density is kilograms per cubic meter ($\text{kg/m}^3$).
  • Volume: The SI unit for volume is the cubic meter ($\text{m}^3$).
  • Time: The SI unit for time is the second ($\text{s}$).
