PHYSICS

PASCAL'S LAW, ARCHIMED'S PRINCIPLE AND BERNOULLI'S PRINCIPLE

โ–ŽPascal's Law

Definition: When pressure is applied to a confined fluid, the pressure change is transmitted undiminished throughout the fluid in all directions.

Key Points:

โ€ข Hydraulic Systems: Enables devices like hydraulic lifts and brakes to amplify force.

โ€ข Force Multiplication: A small force applied over a small area can create a larger force over a larger area.

โ€ข Mathematical Expression:ย  P = F/A

Applications: Hydraulic machinery, automotive braking systems, and various industrial applications.

---

โ–ŽArchimedes' Principle

Definition: An object submerged in a fluid experiences an upward buoyant force equal to the weight of the fluid it displaces.

Key Points:

โ€ข Buoyancy: Explains why some objects float while others sink.

โ€ข Direction of Force: The buoyant force opposes gravity.

โ€ข Mathematical Expression:ย  Fแตฆ = ฯ โ‹… V โ‹… g

Applications: Ship design, hot air balloons, and understanding the behavior of objects in fluids.

---

โ–ŽBernoulli's Principle

Definition: In a flowing fluid, an increase in velocity occurs simultaneously with a decrease in pressure or potential energy.

Key Points:

โ€ข Fluid Dynamics: Explains lift generation for airplane wings and the operation of carburetors.

โ€ข Pressure-Velocity Trade-off: Highlights the relationship between fluid speed and pressure.

โ€ข Mathematical Expression:ย  P + ยฝ ฯ vยฒ + ฯ gh = constant

Applications: Aerodynamics, fluid flow in pipes, and various engineering designs involving fluid movement.

---

โ–ŽSummary

โ€ข Pascal's Law focuses on pressure transmission in fluids, enabling hydraulic systems.

1.Outer ear (external ear):
Outer ear is the part of your ear thatโ€™s visible and contains glands that secrete ear wax.

๐Ÿ‘‰Its funnel-shaped canal leads to your eardrum, or tympanic membrane.

2.Middle ear: The middle ear contain three tiny bones in this area โ€” the malleus, incus and stapes. They transfer sound vibrations to eardrum

๐Ÿ‘‰Theย  middle ears also contain eustachian tubes, which help equalize the air pressure .
3.Inner ear: The inner ear contains two main parts: the cochlea and the semicircular canals.

๐Ÿ‘‰ Cochlea is the hearing organ. This snail-shaped structure contains two fluid-filled chambers lined with tiny hairs. When sound enters, the fluid inside of your cochlea causes tiny hairs to vibrate, sending electrical impulses to your brain.

๐Ÿ‘‰The semicircular canals, also known as the labyrinthine, are responsible for balance.
