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 Electrons encounter resistance when they go through a conductor because of the molecules’ attraction forces. The nature of the material determines how much of this resistance is provided. The resistance of the material determines how much electricity flows as a result of voltage differences. Ohm’s law relates electric current (I), voltage (V), and resistance […]
Introduction Atoms, which give all other matter in the universe its mass, volume, and resilience to survive changes in its physical state, are responsible for the matter’s mass and volume. Each type of matter, molecule, element, or even chemical, has a unique set of features that aid in understanding how that matter is used in […]
Introduction The rate of change in displacement of a moving object is referred to as its velocity. As a result, velocity is a vector quantity, and the velocity-time graph or velocity-time relation is a graphical representation of its fluctuation with time. A velocity-time graph shows the variation of the object’s velocity with time, under different […]
Introduction The measurement of a system or substance’s heat is called its temperature. The pace of an enzyme-catalyzed reaction typically increases as the temperature rises in most chemical processes. Temperature is the internal energy contained within a particular system. Temperature can be measured by a thermometer. Temperature is measured in degrees Celsius, which is written […]
Introduction The matter may be found on Earth in three different states: solid, liquid, or gaseous. Every matter is composed of incredibly tiny building components called atoms and molecules. These particles in a solid are strongly attracted to each other and vibrate in place without passing by each other. Despite not being as strong as […]
Introduction One type of energy that is essential to our existence is light. We are unable to envision a world without light. Light improves the beauty of everything around us and allows us to see. In both science and art, light is a crucial element. One of the crucial scientific instruments that enable scientists to […]
Introduction Pressure can be defined as the force exerted perpendicularly per square unit of area of any object. It is represented by the formula, […]
