Who discovered the law of floatation?
Who discovered the law of floatation? Archimedes What is Class 9 Archimedes Principle? What does Archimedes’ Principle state? Archimedes principle also states that: “When a body is immersed in a liquid, an upward thrust, equal to the weight of the liquid displaced, acts on it.” Thus, when a solid is fully immersed in a liquid, […]
Why 100 efficient engine is not possible?
Why 100 efficient engine is not possible? It is impossible for heat engines to achieve 100% thermal efficiency () according to the Second law of thermodynamics. This is impossible because some waste heat is always produced produced in a heat engine, shown in Figure 1 by the term. What is the difference between Carnot and […]
