Role of Energy in Development Activities There is a very close relationship between the development of a country and the use of energy. To speak the truth, energy use may be considered the first parameter to see how developing a country is. We should pay our first attention to education for the development of our … Read more
Work What is work? If because force-displacement happens then the product of force and component of displacement at the direction of force due to force is work. Work is the product of applied force on a body and its displacement along the direction of a force. Unit of work: J (Joule) Dimension of work, [W] … Read more
Development of Physics Modern civilization is the product of science. Behind this development of science, there are untiring efforts, discoveries, and innovations of scientists. Science has no national or political boundaries. The growth, development, and benefit of science are enjoyed by all people of all nations. From ancient time scientist have been contributing to the development of science. In … Read more
Scope of Physics Since physics is the oldest and the most fundamental branch and other branches somehow flourished on the basis of physics, it is very natural that the scope of physics is very vast. Not only that, different technologies have flourished based on different laws of physics and we are using these in our … Read more
Objectives of Physics Physics unearths the mystery of nature: Physics is the fundamental branch of science because its principles are the basis of other branches of science. For example, the principle of conservation of energy is a principle of physics used to explain the wide range of science starting from the structure of atoms to weather … Read more
What is a generator? What is the function of a generator? A generator is a power generating device with which kinetic energy is converted to electrical energy. The making of a generator is based on the principle of electromagnetic induction. Most of the electricity we use in our homes is produced by generators. Inside a … Read more
Background of Biophysics Biology tries to understand the diversity of the living world and the process through which living things lead their lives. How do the animals collect food, develop relations with one another, perceive the environment and reproduce all these are the subject matter of biology. On the other hand, the laws followed by … Read more
What is radioactivity? Radioactivity is the emission or transmission of ion in the form of waves or particles through space or material medium by the spontaneous disintegration of atomic nuclei. What is called Becquerel? Becquerel is the SI unit of radioactivity, corresponding to one disintegration per second. What is meant by the half-life of radioactive … Read more
