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 ...
The unit of viscosity is Poise. Viscosity measures a fluid’s resistance to flow. It is defined as the ratio of shear stress to shear rate within a fluid. The Poise is the unit used to quantify viscosity, named after French ...
If the diameter of the capillary is doubled, the height of the water surface rising in it remains the same. This is because the height to which a liquid rises in a capillary tube is inversely proportional to the diameter ...
