Question
Which is the most accurate statement of Bernoulli's Principle? I. Fast-moving air causes lower pressure ii. Lower pressure causes fast-moving air iii. Fast-moving air causes constant pressure
Correct Answer
Option A is the correct answer.
Detailed Explanation
Bernoulli's principle states that for an inviscid fluid, an increase in speed occurs simultaneously with a decrease in pressure. Statement i correctly identifies that fast-moving air is associated with lower pressure. Statement ii reverses cause and effect incorrectly.
Hint
Bernoulli describes a relationship, not causation.
