The movement of water from the roots of the plant towards its foliage is not solely due to capillarity. While capillarity contributes to water uptake by plants, other processes like transpiration and root pressure also play significant roles in the ...

The universal law of gravitation was propounded by Newton. Newton formulated this law in his work “Philosophiæ Naturalis Principia Mathematica” published in 1687. It describes the gravitational force between two objects and is a fundamental principle in classical mechanics and ...
Conservation of energy means that energy can neither be created nor destroyed. It can only change forms or be transferred from one object to another. This principle, based on the first law of thermodynamics, asserts that the total energy of ...
The escape velocity of the Earth is 11.2 km/sec. Escape velocity is the minimum speed an object needs to escape the gravitational pull of a celestial body. For Earth, this velocity is approximately 11.2 km/sec, enabling objects to overcome Earth’s ...
Pascal is the unit of pressure. Named after the French mathematician and physicist Blaise Pascal, it measures force applied perpendicular to an object’s surface per unit area. Pascal is commonly used in various fields, including physics, engineering, and meteorology, to ...
1 kg/cm² pressure is equivalent to 10.0 bar. Bar is a unit of pressure equal to 100,000 pascals, and 1 kg/cm² is equivalent to 10,000 pascals. Therefore, 1 kg/cm² pressure is equal to 10.0 bar.
Cusec measures the flow of water. It quantifies the volume of water passing a specific point in a watercourse per unit of time. Cusec, short for cubic feet per second, is commonly used in hydrology, agriculture, engineering, and environmental monitoring ...
A geostationary satellite moves continuously in its orbit due to the gravity applied by the Earth on the satellite. Gravity keeps the satellite in orbit, and the centrifugal force generated by its motion balances this gravitational pull, allowing the satellite ...
Automatic wrist watches get energy from the various movements of our hand. These watches contain a rotor that rotates with the movement of the wearer’s wrist. This movement winds the mainspring, storing energy that powers the watch’s movement and functions ...
When we pull up a bucket of water from a well, we feel that the bucket has become lighter above the surface of the water. As the bucket rises, water drips off, reducing its overall weight. This sensation occurs due ...
