Which of the following quantities have its SI unit named after Blaise Pascal?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. Pressure.
The quantity with the SI unit named after Blaise Pascal is Pressure. The pascal (Pa) is the SI unit for pressure, defined as one newton per square meter (N/m²). Pascal was a French mathematician and physicist who made significant contributions to fluid mechanics and hydrostatics.
Other options:
-
Energy: Its SI unit is the joule (J), named after James Prescott Joule, who studied heat and energy.
-
Work: Also measured in joules (J), as work and energy are related concepts.
-
Power: Its SI unit is the watt (W), named after James Watt, an engineer who improved steam engine efficiency.
Thus, pressure is the correct answer, with its unit honoring Pascal's contributions to science.
