Introduction The neutron was believed to exist before its discovery in 1932 by English physicist Dr James Chadwick. For illustration, it was known that helium had only two protons while having an atomic mass of four. Moreover, after the discovery of neutrons and protons, there was also a new concept ... Read More

Introduction We know very well that the location of the landmass on earth is changing since it was created. In the beginning, there was a huge single landmass on the earth. But by some natural activities, this huge landmass was split into several parts and also move away from its ... Read More

Introduction Light is electromagnetic radiation and is the only part of the electromagnetic spectrum that is visible to the human eye. Photon is the basic unit of light. All electromagnetic energy is made up of photons. They are always neutral. That is, they have no electric charge. They do not ... Read More

Introduction Radiation is a process of transmission of energy from one object to another through the medium or space. It can be ionizing or non-ionizing, which depends upon the energy of the radiation. Ionizing radiation has an energy of more than 10eV and can ionize the particles in their path. ... Read More

Introduction Every matter in the universe is composed of tiny particles called molecules. They attract each other with some attractive force. There exists an intermolecular force of attraction between molecules. Likewise, the electromagnetic force is the force of attraction or repulsion between charged particles. Magnetic force is part of the ... Read More

Introduction If the position of any object changes relative to the time it is said to be in motion. Motion of any object that happens in three ways like one-dimensional motion, two-dimensional motion, and three-dimensional motion. Movement of a train on a straight track, circular motion of the top are ... Read More

Introduction Aeroplanes, space rockets, and model rockets project through the atmosphere by employing concepts of mechanics. These types of machinery contain advanced propulsion systems that generate power and thrust to project the aircraft. The power inside these aircraft is generated by burning fuel or by combustion. The substance that acts ... Read More

Introduction The idea of charge represented by Q in an electric field E and an external source of power V is the context set in this tutorial. The effect of the external power on the charge, its relation with electrical field E, and the result of these experiments are worth ... Read More

Introduction Combustion is a chemical phenomenon that generates heat when a material reacts fast with 𝑂2. The starting substance is known as the fuel, while the 𝑂2 flow is referred to as the oxidizer. The fuel can be solid, gaseous, or liquid, although, for aeroplane propulsion, the liquid is most ...
