Epsilon Naught is synonymous to the permittivity of free space or absolute permittivity or electric constant, represented by the Greek alphabet ε0. The Epsilon Naught value is constant at any part of the universe. It is often miss-used as the value of…
Q1 The velocity of light in the vacuum is represented by which alphabet? The velocity of light in the vacuum is represented by the alphabet ‘c’. Q2 What is the value of hc in Joules? hc = 1.98644568×10-25 J.m. Q4 What…
In physics, hc is a physical constant, where h is Planck’s constant. It is the physical constant that relates the energy carried by a single photon to its corresponding frequency. The velocity of light in the vacuum is represented by…
What is the dimensional formula of Planck’s constant? The dimensional formula of Planck’s constant is ML2T-1. What is the use of Planck’s constant? Planck’s constant is used for describing the behaviour of particles and waves at an atomic scale. Planck’s…
We have known many physical constants in physics. Planck’s constant is one such physical constant which defines the behaviour of particles and waves on the atomic scale along with the particle aspect of light. In this article, let us learn…
What is the gravitational constant? The gravitational constant is the proportionality constant that is used in Newton’s Law of Gravitation. The force of attraction between any two unit masses separated by a unit distance is called the universal gravitational constant…
As the name suggests, the gravitational constant has a constant value which is used in the equation of Newton’s Law of Gravitation. In this article, we will learn about the definition and value of the gravitational constant. What Is the…
The acceleration experienced by a freely falling object due to the gravitational force of the massive body is called acceleration due to gravity and is represented by g measured using SI unit m The value of g depends on the…
What does the value 9.8 m/s2 for acceleration due to gravity imply? The value 9.8 m/s2 for acceleration due to gravity implies that for a freely falling body the velocity changes by 9.8 m/s every second. What does the value 9.8 m/s2 for…
The acceleration experienced by a freely falling object due to the gravitational force of the massive body is called acceleration due to gravity and is represented by g measured using SI unit m The value of g depends on the…
