Why did Archimedes shout 'Eureka!' when he discovered the principle later named after him?
Why did Archimedes shout 'Eureka!' when he discovered the principle later named after him?
Because he noticed that the water in a bathtub overflowed when he stepped into it, realizing the principle of buoyancy.
How is Archimedes’ principle applied in determining the purity of gold in a crown?
How is Archimedes’ principle applied in determining the purity of gold in a crown?
Archimedes’ principle is used to determine the density of the crown compared to pure gold, by observing the water displacement when the crown is submerged.
What is the significance of Archimedes’ principle in ship and submarine design?
What is the significance of Archimedes’ principle in ship and submarine design?
Archimedes’ principle is crucial in ship and submarine design as it helps determine the buoyant force acting on the vessels, ensuring they float and remain stable in water.
