Variation of Acceleration due to gravity due to Altitude Gravity is the force of attraction exerted by earth towards its centre on a body lying on or near the surface of earth. Gravity is merely a special case of gravitation and is also called earth’s gravitational pull. The force of attraction between two bodies on Read more about Variation of Acceleration due to gravity due to Altitude[…]

Exponential Theorem If x ϵ R then . Key points: (1) The series is called exponential series. Thus . In this series (n + 1)th term is called general term. It is denoted by Tn ₊ ₁. Now Tn ₊ ₁ = xⁿ/n! (2) . In this expansion Tn₊₁ = (-1)ⁿ xⁿ/n! (3) . In Read more about Exponential Theorem[…]
Radius of Gyration What is Radius of Gyration? Radius of Gyration is defined as the distance from the axis of rotation to a point where the total mass of the body is supposed to be concentrated so that the moment of inertia about the axis may remain the same. It is denoted by K. Radius Read more about Radius of Gyration[…]

Speed of a Wave Motion The speed of a mechanical wave, is clearly expected to depend upon the properties of the medium through which the wave is travelling. The medium could be a solid, liquid or a gas. All the media are characterized by their physical properties, like mass, density, elasticity and temperature. Waves are Read more about Speed of a Wave Motion[…]

Arithmetical Progression (AP) A sequence is said to be an arithmetical progression, if the difference of a term and its previous term is always same. i.e., an₊₁ – an = Constant = d, ∀ n ϵ N The constant difference, generally denoted by d is called the common different (or) An athematic progression (AP) is Read more about Arithmetical Progression (AP)[…]
Demoivre’s Theorem – Integral and Rational Indices For any real number q and any integer n, (cosθ + i sinθ)ⁿ = cos nθ + i sinnθ If n is a rational number, then one of the values of (cosθ + i sinθ)ⁿ is cos nθ + i sinnθ. Note: (i) it is customary to write Read more about Demoivre’s Theorem – Integral and Rational Indices[…]
AC Voltage applied to a Capacitor When a capacitor is connected to a voltage source in a dc circuit, current will flow for the short time required to charge the capacitor. As charge accumulates on the capacitor plates, the voltage across them increases, opposing the current. That is a capacitor in a dc circuit will Read more about AC Voltage applied to a Capacitor[…]
