The EMF or electromotive force is the energy supplied by a battery or a cell per coulomb (Q) of charge passing through it. The magnitude of emf is equal to V (potential difference) across the cell terminals when there is no current flowing through the […]
Gregory Newton’s is a forward difference formula which is applied to calculate finite difference identity. Regarding the first value f0 and the power of the forward difference Δ, Gregory Newton’s forward formula gives an interpolated value between the tabulated points. The interpolated value is expressed […]
Inductive reactance or simply reactance is not anything but the resistance of an inductive circuit. An inductor competes against the current in a coil which alters the direction and instantaneous magnitude. This opposition is comparable to resistance but always possesses a phase shift between voltage […]
The speed of sound is defined as the travelled by the sound wave that propagates per unit time through an elastic medium. In a perpendicular medium, the speed of the sound depends on the elasticity and density of the medium. If the speed of the […]
De-Broglie waves explain about the nature of the wave related to the particle. Einstein explained the momentum (p) of a photon with the given formula p=mc——–(1) c = speed of light. The energy (E) of a photon is given as E = mc2, E=hλ hλ=mc2 m […]
The crash in which kinetic energy of the system is not conserved but the momentum is conserved, then that collision is termed as Inelastic Collision. Formula of Inelastic CollisionThe inelastic collision formula is articulated as Where mass of body 1 = m1 mass of body 2 = […]
Freefall as the term says, is a body falling freely because of the gravitational pull of our earth. Imagine a body with velocity (v) is falling freely from a height (h) for time (t) seconds because of gravity (g). Free Fall Formulas are articulated as […]
Viscosity is a concept where fluid shows struggle against a flowing, which is being distorted due to extensional stress forces or shear stress. Kinematic viscosity is the sort which is computed by calculating the ratio of the fluid mass density to the dynamic fluid, viscosity […]
Let us imagine a cyclist riding; his velocities differ unceasingly dependent on distance, time etc. At one particular moment if we want to find his velocity it’s not anything but instantaneous velocity. Instantaneous Velocity Formula is made use of to determine the instantaneous velocity of the given […]
Sound Pressure Level Sound pressure is the pressure applied by the sound waves. The sound pressure level is the ratio of the actual sound pressure and the reference level which is the lowest intensity sound that can be heard by maximum people. In other words, […]
