Introduction Two traditions that have been widespread in early Egypt had a big consequence on how cremation is regarded in all other cultures. Firstly, the notion of a dead and resurrected rescuer deity who may grant adherents eternity. The other was the theory of a post-mortem assessment. That indicated whatever ... Read More

Introduction The movement of electrons in an object provides the energy to do work. This energy is called electrical energy. The ratio of electrical energy absorbed is called an electrical power. There are many types of energy like electrical energy, mechanical energy, thermal energy, light energy, and wind energy. In ... Read More

Introduction Radioactivity, as the name introduces, is the emission of energy waves by unstable atomic nuclei of certain elements. There are 38 radioactive elements in the periodic table. The radioactive elements are highly unstable and try to become stable through successive disintegration. During this process, it emits radioactive waves. Essentially ... Read More

Introduction Metrology is the comparison of physical quantity with its equivalent quantity. Measurement is the basis of all scientific research and experiments. Physics is a quantitative science. Physicists always deal with numbers that represent physical measurements. It is the foundation for all technological development. The accuracy of measurement is ... Read More

Introduction Resistance plays a major role in the study of electricity. Electricity is so important for various applications in our daily life. Electric current, which is the flow of electrons, passes through the electric circuit with the component’s resistor, capacitor, inductors are used. The electrical component resistor is used in ...

Introduction Everything around us is visible to our eyes because of light only. Our bodies are completely useless in the absence of light called darkness. Sunlight also acts as a renewable source of energy to generate electricity using solar cells. But, the main question, which was a matter of ... Read More

Introduction The product of a body's mass and its squared distance from its axis of rotation determines its moment of inertia. Using the center of mass (COM) as an example, the moment of inertia is a concept developed from the concept of COM. A centre of mass represents the imaginary ... Read More

Introduction Angular acceleration is a concept of rotational dynamics just as acceleration is defined in the linear case. Physically, it describes the rate of change of angular velocity of a particle. Since rotational motion is performed about an axis or a point, angular acceleration has different values depending upon the ... Read More

Introduction The liquid form of matter resides between both the solid and gas states. Liquids' properties are determined by their form, temperature variations, volume, and intermolecular attractions. There are 3 states of matter: gas, solid, plus liquid. Each form of matter has unique features. Liquid particles are less dense than ... Read More
