 Symmetric and Skew Symmetric Matrices

Symmetric and Skew Symmetric Matrices Symmetric Matrix: A square matrix A is said to be a symmetric matrix if AT = A. Examples: 1. .. Hence A = AT then A is symmetric matrices. .. Hence A = AT then A is symmetric matrices. 3. If A is a square matrix then show that A + AT, Read more about Symmetric and Skew Symmetric Matrices[…] Boyle’s Law

Boyle’s Law Robert Boule studied the variation of volume of a given mass of gas with pressure at constant temperature. The result of his study in the form of law which is known as Boyle’s Law. Boyle’ Law states that the volume of a given mass of a gas is inversely proportional to its pressure Read more about Boyle’s Law[…] Andhra Pradesh Intermediate Public Examinations March 2019 Time Table Released

Determination of Specific Heat of Liquid If volume, radiating surface area, nature of surface, initial temperature and surrounding of water and given liquid are equal and they are allowed to cool down by radiation then rate of loss of heat and fall in temperature of both will be same. i.e., . . . W = Read more about Determination of Specific Heat of Liquid[…] Radical Axis and it’s Properties

Radical Axis and it’s Properties Radical Axis: The radical axis of two circles is the locus of the point which moves such that the lengths of the tangents drawn from it to the two circles are equal. Consider, S ≡ x² + y² + 2gx+ 2fy +c = 0 … (1) and S ≡ x² Read more about Radical Axis and it’s Properties[…] Temperature of the Sun and Solar Constant

Temperature of the Sun and Solar Constant If R is the radius of the sun and T is the temperature, then the energy emitted by the sun per second through radiation in accordance with Stefan’s law be given by P = AσT⁴ = 4πR²σT⁴. By the time it reaches the earth, this energy will spread Read more about Temperature of the Sun and Solar Constant[…] SUAT (Sharda University Admission Test) 2019 Application Started

Direction of Cosines and Direction Ratios Theorem: If l, m, n are the direction cosines of a line L then l² + m² + n² = 1. Proof: l = cosα = x/r m = cosβ = y/r n = cos γ = z/r cos²α + cos²β + cos²γ = 1 (x/r) ² + (y/r) Read more about Direction of Cosines and Direction Ratios[…] Thermometry

Thermometry Thermometry is the science and practice of temperature measurement. Any measurable change in a thermometric probe can be used to mark temperature levels that should later be calibrated against an internationally agreed unit if the measure is to be related to other thermodynamic variables. An instrument is measure the temperature of a body is Read more about Thermometry[…] Amity University Joint Entrance Examination (AMITY JEE) 2019 Exam Date Released
