Solve this multiple-choice question and check the correct answer with its explanation below.

Answer options

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

Correct answer and explanation

Correct answer: Archimedes' Principle

Explanation: āœ… Correct Answer: B) Archimedes' Principle šŸ“š Explanation: Archimedes' Principle states that any body completely or partially submerged in a fluid is acted upon by an upward force equal to the weight of the fluid it displaces. This principle explains why heavy ships made of steel can float on water while a small needle sinks. It is also used to determine the density and purity of gold and other materials.
