Introduction Natural numbers, their additive inverses, and zero are all collectively known as a set of integers. We get a whole number when we subtract a small number from a larger number. However, there are no whole numbers that can represent the difference between a large number and a smaller number, such as 12 – […]
Introduction Although factors and multiples are entirely different concepts, they are related. To determine the factors, we divide the given number by another number, whereas multiples of the given number can be obtained by multiplying the given number by any other number. Multiplication is involved in both ideas. To obtain a given number, we multiply […]
Introduction The ability to work emanates with energy. For any action, we require energy in the form of mechanical, chemical, electrical, static, kinetic, muscular, and other forms. Understanding the several energy sources is necessary for utilising all forms of energy, which can be obtained from various sources, including both natural and artificial ones. Interestingly, natural […]
Introduction Every day, new technological components are developed as technology advances throughout the globe. Electricity powers every other home, public space, and industry. People utilise electricity, and they use it for a variety of things. But how is it that this electric current has a particular level of power and continues to flow without any […]
Introduction H.C. Oersted discovered the magnetic effect surrounding the current-carrying conductor in the 19th century. The region around a magnet or current-carrying conductor where another object feels a magnetic force caused by the magnet or current-carrying body is known as the magnetic field. A current-carrying conductor creates a magnetic field all around it homogeneously due […]
Introduction When people think of algae, they typically picture slimy, green films that grow in still waterways (freshwater and marine). Depending on the species, an Alga may range in size from microscopic to macroscopic and up to a few feet long. Algae are the primary source of atmospheric oxygen that supports many life forms on […]
Introduction The digestive system is made up of organs that digest food, assimilate its nutrients, and eliminate any leftover waste. The gastrointestinal (GI) tract, which connects the mouth to the anus, is essentially a long, continuous tube. For a variety of harmful bacteria, the alimentary canal serves as an immunological barrier. Gut-associated lymphoid tissue (GALT) […]
Introduction Agriculture has played a significant role in the rise of human civilization, but organic farming of domesticated species has produced food surpluses that have enabled people to live in urban areas. Agriculture is the art and science of creating and cultivating soil, increasing yields, and keeping animals. Agriculture and farming have historically been essential […]
Introduction A dam is a physical structure that slows or restricts the flow of subsurface or surface water. Dams build reservoirs that serve multiple purposes, including flood control, irrigation, human consumption, industrial use, aquaculture, and navigability. Although they are more frequently erected on rivers, dams can be constructed anywhere. They may also be built on […]
