Let's Restate
Archimedes' principle, physical law of buoyancy, discovered by the ancient Greek mathematician and inventor Archimedes, states that any body completely or partially submerged in a fluid (gas or liquid) at rest is acted upon by an upward, or buoyant force, the magnitude of which is equal to the weight of the fluid.

Slide 31 - Open vraag

Poetry (Verse) v/s Prose
1. Verse uses fewer words; however, more is expressed than the literal meanings of the words used.
