11. Which of the following is the primary principle behind a simple manometer's operation?

1. Archimedes' Principle
2. Pascal's Principle
3. Boyle's Law
4. Bernoulli's Principle

Answer: B) Pascal's Principle

Explanation:

A simple manometer operates based on Pascal's Principle, which states that in a confined fluid, any change in pressure at any point in the fluid is transmitted undiminished throughout the fluid in all directions. This principle allows the pressure of the fluid to be measured using the height difference in the manometer.
