modeling and analysis of dynamic systems

The state of equilibrium is a state in which the measurable properties of the system do not undergo any noticeable change under a particular set of condition..

The state of reversible reaction at which the concentrations of reactants and products do not change with time is called a state of chemical equilibrium. This state can be recognized by the constancy of certain measurable properties such as pressure, density, colour, concentration, etc. At eq..

Dynamic Nature of Chemical Equilibrium - The state of equilibrium is a state in which the measurable properties of the system do not undergo any noticeable change under a particular set of conditions. We have seen that all observable properties of a system become const..

Advantages of Dimensional Analysis - Dimensional equations are used to validate the correctness of a physical equation. Dimensional equations are used to derive correct relationship between different physical quantities. Dimensional equations are used to convert one system of un..

Thomson's Model - According to this model, an atom can be considered as a sphere of uniformly distributed positive charge in which there are electrons distributed symmetrically. The electrons must be held by the positive charges by electrostatic forces. The mutual repulsions bet..

The measurable/visible properties of the system must remain unchanged with time. Once, an equilibrium is reached the properties of the system do not change with time. When equilibrium is attained, there exists an expression of concentrations of the substances involved in eq..

Suppose you want to buy at least 42 pens and at least 49 pencils from a shop. Which one of the following systems of inequalities models this situation? => x ≤ 42, y ≤ 49 or x ≥ 42, y ≥ 49 or x ≤ 42, y ≥ 49 or x ≥ 42, y ≤ 49..

The atom of an element consists of a small, positively charged nucleus in the centre, which carries almost the entire mass of the atom. The electrons are revolving around the nucleus at high speed. The number of electrons in an atom is equal to the number of protons. Hence it is electricall..

Josh wants to buy at least 13 books and at least 19 cakes from a shop. If y represents the number of books purchased and a represents the number of cakes purchased, then which of the following systems of inequalities models this situation? => y ≥ 13, a ≥ 19 or y ≤ 13, a..

Sunny can afford to buy 14 bananas and 19 apples. He wants at least 12 bananas and at least 16 apples. If x represents the number of bananas, z represents the number of apples that Sunny buys, then which of the following systems of inequalities models this situation? => x ≥ 1..
