The theory that pressure in a confined liquid is distributed equally and undiminished throughout the liquid is called:

The concept that pressure in a confined liquid is distributed equally and undiminished throughout the liquid is known as Pascal's law. This principle emphasizes that when external pressure is applied to a confined fluid, that pressure change is transmitted throughout the fluid in all directions without any loss. This means that no matter where you measure the pressure within that liquid, it will be the same, provided that the fluid is at rest and there are no other forces acting on it.

Understanding Pascal's law is crucial for various applications in hydraulics and fluid mechanics, such as hydraulic lifts and braking systems, where even a small amount of force can be transformed into a much larger force through the use of incompressible fluids. This principle is fundamental to many systems that rely on the transmission of force through fluids.

In contrast, the other principles mentioned, such as Bernoulli's principle, which deals with the relationship between pressure, velocity, and height in flowing fluids, or Boyle's law, which relates the pressure and volume of gases, do not pertain to the transmission of pressure in a liquid as described by Pascal's law. Faraday's law relates to electromagnetic induction and is not relevant in the context of fluid pressure. Thus, the correct answer, identifying the principle of
