What principle says that a body immersed in fluid is buoyed up with force equal to the weight of the displaced fluid?
  1. Parkinson principle
  2. Translatory principle
  3. Newton’s principle of reaction
  4. Archimedes’ principle
Explanation
Answer: D - Archimedes’ principle says that a body immersed in fluid is buoyed up with force equal to the weight of the displaced fluid. This buoyancy, or tendency to float, is dependent upon the percentage of body weight that is made of bone and muscle, as these tissues are more dense and less buoyant.
