Decibel is the unit of sound intensity. It is the ratio of two physical quantities and then the logarithm of the ratio is taken. It is also used in electricity to measure current, voltage, and power....
Isothermal and Adiabatic Processes are two different processes that are related to heat and energy in thermodynamics. Thermodynamics is the branch of physics which deals with the heat transfer and thermal properties of matter. In thermodynamics, the isothermal process is the process that occurs at constant temperature and the exchange of heat and energy takes place between the system and the surroundings. Adiabatic Process in thermodynamics stands for the process where a system is isolated from its surroundings and there is no heat and energy exchange between the system and the surroundings....
Diffraction and Interference are two important phenomena studied in Wave Optics. These phenomena are linked to the Wave Nature of the matter. We know that when photons are emitted from the source they start oscillating in space and the locus of all such oscillating particles in the same phase is called Wavefronts. As per Huygens Wave Theory, each point on the Wavefront acts as a source of secondary Wavelets which later add up to give a new Wavefront. The sources of these Wavefronts can be coherent or non-coherent depending upon whether the phase difference is constant or not. These wavefronts interact with each other and with other particles to give rise to the phenomena of Interference and Diffraction respectively....
Physics has always been a fascinating topic to study. Some of the interesting issues to study include gravity, inertia, distance, displacement, and so on. Science is a comprehensive area that studies various systems such as the human body, the solar system, plant and animal tissue, chemicals, and so on. The center of mass and the center of gravity are two notions that come up frequently in physics. The distinction between the center of mass and the center of gravity will be explained in this article. The major distinction between Center of Gravity and Center of Mass is that the center of gravity is the position at which the entire body weight is balanced, while the center of mass is the position at which the entire mass of the body is directed....
Pressure refers to the Physical force exerted on an object per unit area. It can alternatively be described as the force-to-area ratio (over which the force is acting). F/A is the basic pressure formula (Force per unit area). Pascals is a unit of pressure (Pa). Absolute, atmospheric, differential, and gauge pressures are examples of pressures. Have you ever noticed that when you drink from a straw, you actually suck the air out of it? You’re actually applying ‘Pressure’ while sipping your beverage....
Force is just defined as a push or pull of an object with the mass that causes it to change its velocity. It is an external agent that is capable of changing the state of a particular body neither in a rest position nor in motion. It has both magnitude and direction. It can be measured using a spring balance. The formula of force is F = ma, where m = mass of the object, a = acceleration....
The difference between Conductors and Insulators is that conductors allow the flow of electric current, while insulators do not. The reason behind this is the presence of free electrons in conductors, while insulators lack them. They differ in their electrical resistance, electron mobility, and thermal conductivity. In this article, we will learn the differences between conductors and insulators in detail....
Pressure is the force per unit area applied toward a course perpendicular to the outer layer of an item. Numerically, it is represented with a ‘P’. To keep it precise, it is an amount of force following up on a unit area. The simple equation for pressure is P = F/A where P is Pressure, F is Force, and A is Area....
Stress and Strain is an important concept in the field of Material Science and Metallurgy to get into insights about the strength of the material. When a material is put under pressure or has a load applied to it, it develops stress is developed. When a solid is put under stress, it has the ability to deform. This deformation is called Strain. The stress is the pressure per unit area of the material, and the resulting strain is the deformation that occurs as a result of this stress. Strain and stress are strongly intertwined because strain occurs solely as a result of stress....
The most common type of diode is a semiconductor diode. Only when a specified threshold voltage is present in the forward direction (i.e. the “low resistance” direction) do these diodes begin to conduct electricity. When current flows in this direction, the diode is said to be “forward biased.” The diode is considered to be “reverse biased” when it is linked in the opposite direction (i.e. the “high resistance” direction) within a circuit....
Conduction current is the movement of electric charge through a conducting material, like a wire. Displacement current is a concept in electromagnetism, which represents changing electric fields in non-conductive materials. In this article, we will learn the differences between Conduction Current and Displacement Current in detail....
Difference Between PSI and Bar: Pressure measurement is a crucial part of several disciplines, including engineering, physics, and chemistry. Pressure is measured in a variety of units, including PSI and Bar. PSI is an abbreviation for pounds per square inch, while Bar is a metric pressure measurement unit. Understanding the differences between these units is critical for correct measurement and calculation. The psi measurement unit seems to be more precise and may be used to measure stress as well as pressure. Bar represents the load exerted at right angles to a unit volume of a surface to represent pressure. 100,000 Pa is precisely equivalent to one bar.PSI is widely utilized in the United States, Bar is widely used in many other nations worldwide....
