Learn Science With Executive Makers [GS] [Science] Wave, Mechanical Wave, Sound Wave For All Competitive Exams Wave : A wave is a disturbance which propagates energy from one place to the other without the transport of matter. Waves are of two types (1) Mechanical wave (2) Non-Mechanical wave Mechanical Wave : The waves which require […]
Learn Science With Executive Makers [GS] [Science] Law of Floatation, Buoyant Force, Archimedes Principle, Density & Relative Density Buoyant Force : When a body is immersed partly or wholly in a liquid, a force acts on the body by the liquid in the upward direction. This force is called buoyant force or upthrust. It is […]

PRESSURE Pressure : Pressure is defined as force acting normally on unit area of the surface. P = F/A = Force/Area SI unit of pressure is N/M2 also called pascal (Pa). Pressure is a Scaler quantity. If the area is less then the pressure will be more. Atmospheric Pressure : It is that pressure which […]
