A compound-complex sentence combines the compound and the complex sentence. The compound part means that it has two or more complete sentences. The complex part means that it has at least one incomplete sentence.
Archimedes' principle. Archimedes' principle states that the upward buoyant force that is exerted on a body immersed in a fluid, whether fully or partially submerged, is equal to the weight of the fluid that the body displaces and acts in the upward direction at the center of mass of the displaced fluid. Archimedes' principle is a law of physics fundamental to fluid mechanics. It was formulated by Archimedes of Syracuse.
What two contributions to mathematics and physics did Archimedes make? Archimedes contributed to physics by discovering Archimedes' Principle, the law that an object submerged in a fluid is acted upwards upon by a force equal to the displaced â¦ weight. In mathematics, he provided the proof that an area of a portion of a parabola is 4/3 the area of a corresponding triangle.
