Introduction The rigid body is considered as translational zero or negligible deformation. It is also determined as the body that has continuous mass distribution. The rigid body basically has 2 different types of motions that are translational motion and rotational motion. The rigid body when travelling with these types of motions is travelling with displacement in an equal time interval. In the case of the transitional motion the body will travel with same displacement in an equal time interval and in other cases that as rotational motion the body will travel with the same angular displacement in an equal time ...

Introduction The ratio of inertial forces is a significant part of this kind of number. Inertial forces, related to viscous forces are relevant in this regard. The formula for calculating the Reynolds number is Reynolds Number = Inertial Force/Viscous Force. This formula is also presented as $\mathrm{R_e \:=\:\rho\: VD/ \mu}$. As per this formula, $\mathrm{R_e}$ is the value of the Reynolds number. The value of density within a fluid is presented by $\mathrm{\rho}$. This equation is important as it also presents the velocity of the flow with the symbol V. D is the indicator of pipe diameter. The viscosity of ... Read More

Introduction The reflection of sound waves from multiple closed surfaces is associated with the function of reverberation. The reflection might occur from the air, furniture in the area or even in the presence of humans. This effect is quite similar to that of echo but the distance between the source and the obstacle through which the sound gets reflected is lesser compared to the case of echo. Once the sound waves get reflected from one surface to another the phenomenon starts decaying since the waves get absorbed by the surfaces of the objects. What is reverberation? The phenomenon of ...

Introduction In introducing this it needs to be understood that the phenomenon of resonance is used in determining the unknown frequency. It is a special phenomenon, which is used in our daily lives, majorly in the field of music. It is sometimes used to understand several musical instruments, and sometimes used to increase the extent of intensity of sounds' ' in several instruments of music. However, to tune the radio receiver, the phenomenon of resonance is used. Definition of Resonance Resonance is a peculiar phenomenon, where an external force or any other forces of vibrating substances tends to exert ... Read More

Introduction The resolving capacity of a particular instrument is very important as it allows the detailed analysis of a particular object. Resolution denotes the level of details that is observed by a microscope. It refers to the ability of a particular optical system to create distinguishable images of the objects which are separated by little angular distances. For microscope and telescope, the resolving power can be defined as the capacity of an optical instrument to recognize and distinguishes a certain distance between 2 objects. Resolving Power of Microscopes and Telescopes The resolving power of a microscope and telescope refers to ... Read More

Introduction Calculation of total circuit resistance is important to know the total amount of resistors used in both parallel and series resistors. Voltages can also be measured by significant resistive combinations. A circuit, associated with a resistor that helps in combining several parallels and series resistors is regarded as a resistor combination. Resistor network plays an important role. The method of calculating in which the resistance terms and values are calculated is simple and the same for both parallel and series combinations. The same value of current and resistors possess the same voltage. Components of parallel and series resistor Mixed ... Read More

Introduction The current flow and voltage level are reduced by a resistor within a circuit. In most of circuits, more than one resistor is found that helps in limiting the charge flow within a circuit. There are two simplest resistor combinations, namely Parallel and series. The combination of these two resistors is very important as the overall flow of charge is integrally connected to this. Importance of a combination circuit A combination circuit is an important component for a series and parallel resistors. A resistor is known as an ohmic device in which V = IR (Hope et al. ...

Introduction The resistor is a tiny electric body having printed with many colours on the body to denote the different values of electrical resistance. The colour band of the resistor is called resistor colour code. The electric designers print the rate of tolerance, resistance value as well as wattage rating on the body of a resistor in numerical or alphabetical form. This can be seen in a large power resistor. The number bands of the resistor body presented with the variation of three to six numbers. Among the three numbers, the first two numbers stand for the resistance ... Read More

Introduction Electrical resistivity is known to be the reciprocal of electrical conductivity. Resistivity of various materials is mentioned through the function of temperature as it rises with temperature due to the electron-phonon connection. Resistivity of the material is restricted even at the ultimate zero due to the existence of small amounts of defects and impurities. Hence, it is said that conductivity and resistivity are limited and confined at ultimate zero. Resistivity's temperature coefficient is mentioned as the transformation in resistivity per unit material's resistivity per degree transformation in temperature. The electrical resistivity of various materials is the calculation of the ... Read More
