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....
In shaded locations, the heat index is a temperature that combines air temperature and relative humidity. Perspiration or sweating is a natural way for the human body to cool down. Sweat evaporation is responsible for removing heat from the body. High relative humidity, on the other hand, slows evaporation. When the temperature is 32 degrees Celsius and the relative humidity is 70%, the heat index number equals the actual air temperature....
Dispersion of Light happens when white light is split into its constituent hues due to refraction. Dispersion of Light can be achieved through various means but the most common way to achieve dispersion of light is through Prism. Dispersion of light by a prism results in the breaking of white light into its seven constituents....
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....
Force is pushing or pulling any item coming about because of the object’s connection with another object. Without force, nothing can be moved, halted, or shift the course. It is a quantitative communication between two actual bodies, between an article and its current circumstance. There are different sorts of powers in nature. Assuming an object is in its movement state then its present status will be either static or movement. Its position might be changed assuming it is pushed or pulled. The outside push or pull applied on the object changes its present status of movement is known as Force. This power can be of various sorts....
Capacitance is defined as the capacity of any material to store electric charge. The substance that stores the electric charge is called a capacitor, i.e. the ability of the capacitor to hold the electric charge is called capacitance. It is denoted with the symbol C and is defined as the ratio of the electric charge stored inside a capacitor by the voltage applied....

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....
Data acquisition holds a role, in the field of data science and engineering. In this article, we will explore the definition of data acquisition, its purpose, and why it’s important. Additionally, we will go through the types of data acquisition systems how they function, and the factors to consider when setting them up. We will also discuss the advantages and disadvantages associated with data acquisition....
The resistance to motion that most fluids provide is referred to as “viscosity.” When there is relative motion between layers of fluid, viscosity develops. It precisely measures the resistance to flow caused by internal friction between fluid layers as they pass through one another during fluid flow. Viscosity may also be defined as a measure of a fluid’s thickness or barrier to passing items through it....
Resistance is the physical property of the material which opposes the current flow in the circuit whereas resistivity is the intrinsic property that helps us understand the relation between the dimension of the substance and the resistance offered by it....
