The Aufbau principle can be used to understand the location of electrons in an atom and their corresponding energy levels. For example, carbon has 6 electrons and its electronic configuration is 1s 2 2s 2 2p 2. It is important to note that each orbital can hold a maximum of two electrons (as per the Pauli exclusion principle).
Examples of D’Alembert Principle. 1D motion of rigid body: T – W = ma or T = W + ma where T is tension force of wire, W is weight of sample model and ma is acceleration force. The 2D motion of rigid body: For an object moving in an x-y plane the following is the mathematical representation: Fi= -mrc where Fi is the total force applied on ...
Dec 10, 2017 · Bernoulli’s principle states that. The total mechanical energy of the moving fluid comprising the gravitational potential energy of elevation, the energy associated with the fluid pressure and the kinetic energy of the fluid motion, remains constant. Bernoulli’s principle can be derived from the principle of conservation of energy.
Heisenberg’s uncertainty principle states that it is impossible to measure or calculate exactly both the position and the momentum of an object. This principle is based on the wave-particle duality of matter. Although Heisenberg’s uncertainty principle can be ignored in the macroscopic world (the uncertainties in the position and velocity ...
Archimedes’ Principle Applications. Following are the applications of Archimedes’ principle: Submarine: The reason why submarines are always underwater is that they have a component called ballast tank which allows the water to enter making the submarine be in its position underwater as the weight of the submarine is greater than the ...
Defining the Huygens Principle. Huygens principle is a method of analysis applied to wave propagation problems both in the far-field limit and near-field diffraction and reflection. It states that: “Every point on a wavefront is in itself the source of spherical wavelets which spread out in the forward direction at the speed of light.
The Principle of UV-Visible Spectroscopy is based on the absorption of ultraviolet light or visible light by chemical compounds, which results in the production of distinct spectra. Spectroscopy is based on the interaction between light and matter. When the matter absorbs the light, it undergoes excitation and de-excitation, resulting in the ...
Dimensional analysis is a fundamental aspect of measurement and is applied in real-life physics. We make use of dimensional analysis for three prominent reasons: To check the consistency of a dimensional equation. To derive the relation between physical quantities in physical phenomena. To change units from one system to another.
Infrared Spectroscopy generally refers to the analysis of the interaction of a molecule with infrared light. The IR spectroscopy concept can generally be analyzed in three ways: by measuring reflection, emission, and absorption. The major use of infrared spectroscopy is to determine the functional groups of molecules, relevant to both organic ...
Working Principle of a Transformer. The transformer works on the principle of Faraday’s law of electromagnetic induction and mutual induction. There are usually two coils – primary coil and secondary coil – on the transformer core. The core laminations are joined in the form of strips. The two coils have high mutual inductance.
