James Chadwick, a British physicist, was awarded the Nobel Prize in 1935 for his discovery of the neutron. Bombarding elements with neutrons can result in the penetration and splitting of nuclei generating an enormous amount of energy. This way, Chadwick’s…
John Dalton’s major contribution was his theory on atoms which consists of five parts as follows: Dalton made a lot of discoveries based on his observations.
Ernest Rutherford, a New Zealand chemist is regarded as the “father of nuclear physics.” He was the first to propose that an atom comprises a small charged nucleus surrounded by empty space and is circled by tiny electrons which later,…
J.J Thomson, an English physicist and a Nobel Laureate in Physics, is credited and honoured with the discovery of the electron, which was the first subatomic particle to be discovered. Thomson managed to show that cathode rays were composed of…
Albert Einstein Photon, also known as light quantum, is a tiny energy packet of electromagnetic radiation. This concept originated in Albert Einstein’s explanation of the photoelectric effect, in which he proposed the existence of discrete energy packets during the transmission…
Q1 When does terminal velocity exist? When the speed of a moving object is no longer increasing or decreasing; the object’s acceleration (or deceleration) is zero. Q2 What is terminal velocity? Terminal velocity is defined as the highest velocity attained…
What is Terminal Velocity? Terminal velocity is defined as the highest velocity attained by an object falling through a fluid. It is observed when the sum of drag force and buoyancy is equal to the downward gravity force acting on…
The phase rule describes the possible number of degrees of freedom in an enclosed system at equilibrium, in terms of the number of separate phases and the number of chemical constituents in the system. It was deduced by J.W Gibbs…
Q1 What is a semiconductor? A semiconductor has an electrical conductivity value between that of a conductor, such as metallic gold, and an insulator, like glass. Its resistivity reduces as the temperature increases. Q2 What is the hall effect? Hall…
Hall effect is defined as the production of a voltage difference across an electrical conductor which is transverse to an electric current, and with respect to an applied magnetic field, it is perpendicular to the current. Edwin Hall discovered this…
