The water level remains the same when the ice cube melts. This is because a floating object displaces an amount of water equal to its own weight. Since water expands when it freezes, the volume of the melted ice cube ...

In a state of weightlessness, the shape of a candle flame will be spherical. Without the influence of gravity, convection currents do not form, causing the flame to become spherical as it is no longer pulled upwards. This phenomenon is ...
The liquid rises to a higher height than water in a capillary tube because the surface tension of the liquid is higher than that of water. This stronger surface tension pulls the liquid upward, resulting in a greater capillary rise ...
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 ...
