In classical mechanics, a constraint is a relation between coordinates and momenta (and possibly higher derivatives of the coordinates). In other words, a constraint is a restriction on the freedom of movement of a system of particles. The only difference between a constraint equation and eg a conservation equation is that a conservation equation is physics, but Read more about Constraint Relations[…]
Hello Guys…!! The very first thing you might get into your mind is, “What are amino acids?” There are many types of amino acids and each are different from the other. Amino acids are the essential building blocks of each cell in an organism. Here are few details, types of amino acids and their properties. Read more about Amino Acids[…]
Have you been constantly confused about the signs and the properties of ions, electrodes etc?? Is it slipping away from your mind always? Here goes the tips to remember those easily and helps you score well in competitive examinations by even saving a lot of time. Cations and anions: Cations are positively (+) charged ions while anions are negatively (−) Read more about Best Mnemonics to follow in Chemistry[…]
L-R Series circuit (inductor in series with resistor): A resistor-inductor circuit (RL circuit) is an electric circuit composed of resistors and inductors driven by a voltage or current source. A first order RL circuit is composed of one resistor and one inductor and is the simplest type of RL circuit.Using Kirchhoff’s voltage law According to the law, the Read more about LR and RC circuits[…]
CARBENES Carbenes are highly reactive molecule containing a divalent carbon atom. Neutral, divalent, highly reactive in nature. They are highly unstable that’s why highly reactive in nature. Simplest carbene is General preparation: Carbenes are related to carbanions through α – elimination reaction Hybridization of the divalent carbon may be sp² as well as sp. sp² hybrid carbine is Read more about CARBENES & NITRENES[…]
Grouping of cells Series: Eeq = ∑E1 And req = ∑ri; . If S number of identical cells each of marking (E, r) are connected in series across an external resistor R. Eeq = SE And req = Sr ⇒ . Out of these S cells if x number of cells are reversely connected then Eeq = (S – 2x)E, . Parallel: If P number of Read more about GROUPING OF CELLS[…]
1st Law / Junction Rule: Across any junction algebraic sum of all currents is zero; this is a consequence of Conservation of charge principle. 2nd Law / Loop Rule: This is a consequence of conservation of energy principle. Across any loop i.e. closed path work done by all agents is equal to zero. This follows from Read more about Kirchhoff’s Laws[…]
Dipole: Electric Dipole and Dipole Moment: Two equal and opposite charges separated by a distance together constitute a dipole.Dipole moment defined as the simple product of magnitude of either charge and the distance of separation between the two charges. . Dipole moment always points from -q to +q. Its SI unit is coulomb metre (Cm). ELECTRIC FIELD DUE TO Read more about ELECTRIC DIPOLE, its MOMENT, INTENSITY[…]
