The ‘fair cup’ or Pythagorean cup, dates from about the 6^th century?

AD
BC
CD
None of the above

Correct Answer

A. BC

Explanation

The correct answer is BC. The fair cup or Pythagorean cup is believed to have originated around the 6th century BC. This cup has a unique mechanism that prevents excessive drinking. When the cup is filled beyond a certain level, it automatically drains all the liquid, ensuring moderation in drinking. This invention is attributed to the ancient Greek philosopher and mathematician Pythagoras, hence the name Pythagorean cup.

Archimedes is credited with the discovery of Archimedes’ principle, which relates the?

Hydrolysis
Hydrostatics
Buoyancy force
None of the above

Correct Answer

A. Buoyancy force

Explanation

Archimedes is credited with the discovery of Archimedes' principle, which relates to the buoyancy force. Buoyancy force is the upward force exerted on an object immersed in a fluid, such as water, due to the difference in pressure between the top and bottom of the object. This principle states that the buoyant force on an object is equal to the weight of the fluid displaced by the object. This discovery by Archimedes has significant implications in understanding the behavior of objects in fluids and is a fundamental principle in hydrostatics.

The concept of pressure and the way it is transmitted by fluids were formulated by?

Archimedes
Lord Byron
Shelley
Blaise Pascal

Correct Answer

A. Blaise Pascal

Explanation

Blaise Pascal formulated the concept of pressure and the way it is transmitted by fluids. He conducted experiments and developed the principle known as Pascal's law, which states that when a pressure is applied to a fluid in a confined space, it is transmitted equally in all directions. This concept is fundamental in various fields such as engineering, physics, and hydraulics.

Pascal made contributions to developments in both hydrostatics and?

Pascaline
Hydro-electrolysis
Shear Stress
Hydrodynamics

Correct Answer

A. Hydrodynamics

Explanation

Pascal made contributions to developments in hydrostatics, which is the study of fluids at rest, and hydrodynamics, which is the study of fluids in motion. Hydrodynamics involves understanding the behavior of fluid flow and the forces that act on it. Pascal's contributions in this field helped advance our understanding of fluid mechanics and laid the foundation for further developments in areas such as fluid dynamics and aerodynamics.

Hydrostatics offers physical explanations for many phenomena of?

Physics
Nature
Everyday life
None of the above

Correct Answer

A. Everyday life

Explanation

Hydrostatics is a branch of physics that deals with the study of fluids at rest and the forces exerted by these fluids. It provides physical explanations for various phenomena that occur in everyday life, such as the behavior of fluids in containers, the buoyancy of objects in water, and the pressure exerted by fluids on surfaces. Therefore, the correct answer is "Everyday life."

Why wood and oil float on water, why the surface of the water is always flat and horizontal, these studies are related to the subject of?

Buoyancy
Electrostatic
Hydrostatics
Geophysics

Correct Answer

A. Hydrostatics

Explanation

Hydrostatics is the branch of fluid mechanics that deals with the study of fluids at rest. It includes the study of buoyancy, which explains why wood and oil float on water. The surface of the water is always flat and horizontal due to the principle of hydrostatic equilibrium, which states that the pressure at any point in a fluid at rest is the same in all directions. Therefore, the correct answer is Hydrostatics.

Archimedes principle state a force on an object is submerged in a fluid to the weight of the fluid displaced by the?

Distance
Displacement
Fluid
Object

Correct Answer

A. Object

Explanation

Archimedes' principle states that the buoyant force acting on an object submerged in a fluid is equal to the weight of the fluid displaced by the object. This means that the upward force exerted on the object (buoyant force) is equal to the downward force exerted on the fluid (weight of the fluid displaced). Therefore, the correct answer is "Object" as the force on the object is equal to the weight of the fluid displaced by it.

Some principles of hydrostatics have been known in an empirical and?

Study
Stoic study
Intuitive sense
Renaissance

Correct Answer

A. Intuitive sense

Explanation

The given question is asking for an explanation for the correct answer "Intuitive sense." In the context of hydrostatics, the term "intuitive sense" refers to an understanding or knowledge that is gained through intuition or instinct rather than through formal study or empirical evidence. This suggests that some principles of hydrostatics were discovered or understood by individuals through their natural ability to perceive or sense the behavior of fluids, rather than through systematic scientific investigation. This explanation aligns with the idea that certain aspects of hydrostatics were known before they were formally studied or explained.

Hydrostatics is relevant to the field of geophysics and?

Geochemistry
Biochemistry
Geography
Astophysics

Correct Answer

A. Astophysics

Explanation

Hydrostatics is relevant to the field of astrophysics because it deals with the study of fluids at rest and the forces exerted on them. In astrophysics, the behavior of fluids such as gases and plasma in celestial bodies like stars and planets is of great importance. Understanding the principles of hydrostatics helps in analyzing the structure, composition, and dynamics of these celestial bodies, as well as in explaining phenomena such as stellar evolution, planetary formation, and the behavior of interstellar medium.
