What is the formula for specific heat capacity?Heat Transfer:In physics, the heat transfer is the part of the energy transfer, where the energy transferred from a higher source to the lower source. To the transferred of energy from a lower source to the higher source, there is a need to...
According to the potential energy definition, it is the energy that is stored in an object. Know what is potential energy, potential energy definition, its types and examples at BYJU’S - The Learning App.
What is the formula for surface tension? Cohesion Force: The force of attraction between the molecules of the same substance is called the cohesion force. It is also called the intermolecular attraction. Adhesive force is the force of attraction between the molecules of different substances. ...
So the farther apart the particles are, and/or the less massive the particles, the less the gravitational force. The standard formula for the law of gravitation goes [source: UT]: Gravitational force = (G x m1 x m2) / (d2) where G is the gravitational constant, m1 and m2 are the ...

A capacitor is a passive electrical component that can store energy in the electric field between a pair of conductors (called “plates”).In simple words, we can say that a capacitor is a device used to store and release electricity, usually as the result of a chemical action. Also ...
41. What is the formula for Bragg's Law?d sin θ = nλ 2d sin θ = 2nλ 2d sin θ = nλ 2d sin θ = n2λAnswerThe correct answer is: C) 2d sin θ = nλExplanationBragg's law is expressed as: 2dsinθ=nλWhere:
A formula is a fixed way of doing or making something, often expressed in mathematical or symbolic terms, while a formulation is the process or result of creating a particular combination, especially in a specific context or for a purpose. ...
