Boltzmann Constant The Stefan – Boltzmann Law deals with the black body radiation. It states that the total energy radiated per unit surface area of a black body in unit time is directly proportional to the fourth power of the black body’s thermodynamics temperature. In thermodynamics, Boltzmann constant is the physical constant relating average kinetic Read more about Boltzmann Constant[…]
Relation between Angular Velocity and Linear Velocity What is Angular Velocity? Angular velocity is the rate of velocity at which an object or a particle is rotating around a center or a specific point in a given time period. It is also known as rotational velocity. We can also define the angular velocity of a Read more about Relation between Angular Velocity and Linear Velocity[…]
Elastic and Proportional Limit When a material undergoes the deformation by the influence of some external force, it also exhibits the internal force which opposes then deformation and regains its original form. When a material deformed under an external force the material will break, we can call it as the elastic limit of the material. Read more about Elastic and Proportional Limit[…]
Escape Velocity When a particle is thrown vertically upwards, it reaches a certain height and comes back to its original position. But when it is given greater initial velocity, it reaches greater height before coming back. A particle can be thrown up with a certain minimum initial velocity so that, the particle goes beyond the earth’s Read more about Escape Velocity[…]
Effect of Temperature on the Time Period of a Simple Pendulum The time represented by the clock hands of a pendulum clock depends on the number of oscillations performed by pendulum. Every time it reaches to its extreme position. The second hand of the clock advances by one second that means second hand moves by Read more about Effect of Temperature on the Time Period of a Simple Pendulum[…]
Percentage Error While measuring any physical quantity, it is impossible in principle to find its true value. The difference between the measured and the true values of a physical quantity is called the error of measurement. To determine if a value is accurate compare it to the accepted value. As these values can be anything Read more about Percentage Error[…]
Rydberg Formula Rydberg formula is a mathematical formula used to predict the wavelength of light resulting from an electron moving between energy levels of an atom. If the state of an electron in a hydrogen atom is slightly perturbed, then the electron can make a transition to another stationary. The transition will emit a photon Read more about Rydberg Formula[…]
Electric Field Due to an Isolated Point Charge Electric Field is a force produce by a charge near its surroundings. This force is exerted on other charges when brought in the vicinity of this field. The SI unit of Electric field is N/C. Electric field due to a charge at a point is the force Read more about Electric Field Due to an Isolated Point Charge[…]
Relation between Field and Potential Electric Field is a force produce by a charge near its surroundings. This force is exerted on other charges when brought in the vicinity of this field. The SI unit of Electric field is N/C. Electric field due to a charge at a point is the force that a unit Read more about Relation between Field and Potential[…]
