When an object is completely or partially immersed in a liquid, the apparent reduction in its weight is equal to the weight of the fluid displaced by that object. This principle is known as Archimedes’ principle. It explains buoyancy and ...

Archimedes’ law is related to the Law of flotation. It states that an object submerged in a fluid experiences an upward buoyant force equal to the weight of the fluid displaced by the object. This principle explains why objects float ...
The ship remains floating while an iron needle sinks in water based on Archimedes’ principle. This principle states that an object immersed in a fluid experiences an upward buoyant force equal to the weight of the fluid displaced by the ...
The oil rises in the lamp wick due to capillary phenomenon. The wick’s fibers act as tiny tubes, creating capillary action. This action draws the oil upwards against gravity, allowing it to reach the flame, where it vaporizes and burns. ...
When two capillaries of different diameters are immersed vertically in a liquid, the height of the rising liquid will be higher in the smaller diameter capillary. This phenomenon is governed by the capillary action, where the height of liquid rise ...
When a bucket of water is rotated very fast in a vertical circle, the water does not fall from the bucket even from its highest position because centrifugal force is greater than the weight of water. Centrifugal force pushes the ...
When milk is churned vigorously, cream separates from it due to centrifugal force. Centrifugal force acts outward from the center of rotation, causing denser milk particles to move towards the outer edges of the container, while lighter cream particles move ...
When a cyclist turns a corner, he leans inwards. Leaning inwards helps the cyclist counteract the centrifugal force generated during the turn, maintaining balance and stability. This technique allows for smoother and more controlled maneuvering around the corner, reducing the ...
A cyclist bends while taking a turn to ensure that the center of gravity remains inside the base, preventing the bicycle from falling. This action helps maintain stability by redistributing the rider’s weight and aligning the forces acting on the ...
Railway tracks are banked on curves so that the required centripetal force can be obtained from the horizontal component of the train’s weight. This helps to prevent derailment by ensuring that the train remains securely on the tracks, balancing the ...
