What is density?
Density is a physical characteristic, and calculates of mass per unit of volume of a material or substance. It is a measurement of the quantity of matter in a given volume of something.
The higher an object's density, the higher it's mass per unit of volume. The average density of an object equivalent its total mass divided by its total volume. A denser object (like iron) will have less volume than an equal mass of some less dense substance (like water).
Explain Electromagnetism
Explain Constant current system Constant current system : - In this process, the charging current is kept constant by varying the supply voltage to overcome the enhanced back
Frequency The number of vibration done per second by an oscillation body is known its frequency. It is denoted by V. The S.I unit is Hz. V=1/T
As shown in the figure below, a bubble of gas with a volume of 1.20 cm3 is released under water. As it rises to the surface, the temperature of the bubble enhances from 27°C to
The atomic weight of an element is double its atomic number. If there are four electrons in 2P orbital, the element is : (1) C (2) N (3) O

Landauer's principle: A principle that states it doesn't take energy to compute data explicitly, but rather it takes energy to erase any data, as erasure is a significant step
Q. State the law of conservation of electric charges? The entirety charge in an isolated system always remains constant. For instance Uranium ( 92 U 238 ) can decay by emittin
