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: 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 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[…]

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 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[…]

Asymptotes of Hyperbola If the length of the perpendicular from a point on a hyperbola to a straight line tends to zero as the point on the hyperbola moves to infinity along the hyperbola, then the straight line is called the asymptote of the hyperbola. The asymptote of a hyperbola can be found as follows. Read more about Asymptotes of Hyperbola[…]
