Different Layers of Earth’s Atmosphere

Praveen Varghese Thomas
Updated on 05-Feb-2024 16:08:52

Introduction Different layers of earth’s atmosphere play a major role in our daily life. We know that the sunlight we receive on this Earth is actually very harmful. Indeed, if unfiltered, it can even cause skin cancer. So how are humans surviving this onslaught of radiation every day? We are safe because nature has provided us with a shield in the form of the ozone layer, which blocks harmful rays of the sun from reaching the earth. But this ozone layer is just a small part of the enormous layer of gases that envelops our planet from the surface ... Read More

Difference between Asteroid and Comet

Introduction Difference between Asteroid and comet is an important concept of Astronomy. Celestial bodies like planets, asteroids, comets etc orbit the sun. Asteroids and comets are sometimes termed as “time capsule” since they hold information about the solar system. They both are made from the leftovers of the moon and planets and formed about 4.5 billion years ago. These two sometimes can have unusual orbits due to gravitational disturbances and drift nearer to any planet. The main difference between asteroids and comets is their composition i.e., with what they are made of. Asteroids are metallic or rocky bodies without ... Read More

Dielectric Strength

Updated on 05-Feb-2024 16:16:33

Introduction Dielectric strength is a property of insulating materials. Electricity is the utility power that drives the entire world's equipment in the way that we see it today. The transmission and distribution of electric power for industrial and household purposes are through insulated cables. Dielectric strength materials available intrinsically in cable insulations. The dielectric strength prevents electricity leakage from the transmission strands (usually copper) inside the insulation. This tutorial covers the definition, methods of ascertaining the dielectric strength of a material, and other related concepts core to dielectric strength. Dielectric Materials Some insulating materials have the functionality of storing ... Read More

Diatomic Gas

Introduction Diatomic gases are plenty in nature. A two-atom molecule is referred to as a diatomic molecule. At normal temperatures, almost all diatomic molecules are gases. Diatomic molecules are found in substances like carbon monoxide and nitric oxide. What is a Diatomic Molecule? Diatomic molecules or elements are those that have two atoms linked together chemically. When two atoms are identical, as in the case of the oxygen molecule, they combine to form a homonuclear diatomic molecule; but, when they are dissimilar, as in the case of carbon monoxide, they combine to produce a heteronuclear diatomic molecule. Heat capacity ... Read More

Equation of destructive interference

Updated on 05-Feb-2024 16:22:29

Introduction Destructive interference is a concept based on superposition of waves. Wave is the disturbance in a medium to transfer energy without the transfer of mass. Waves are usually in a periodic motion, like a simple harmonic oscillator. They have crests and troughs. The amplitude of the wave is the height of the wave. The distance covered between two consecutive crests is called the wavelength of the wave. The number of waves passed per second is called the frequency of the wave. Phase is not the property of waves. But it gives the relation between two signals with the same ... Read More

Aerofoil Terminologies, Lift Coefficient

Praveen Varghese Thomas
Updated on 05-Feb-2024 16:29:26

Introduction Aerofoil terminologies and lift coefficient are important concepts to determine the design of a flying object. Have you ever wondered how aeroplanes stay up in the air? What is it about their design that allows them to soar across the sky? The answer, as it turns out, is as interesting as the question. Let us start by discussing the forces that aid in keeping aeroplanes up in the air. These are four in number, and we call them drag, thrust, weight, and lift. Together, they make it possible for aeroplanes to fly. Of these, the concept of lift is ... Read More

Gamow Theory of Alpha Decay

Praveen Varghese Thomas
Updated on 05-Feb-2024 16:31:23

Introduction Gamow theory of Alpha decay explains the radioactive process of decay effectively. Elements in nature are flexible. That is, to say, it is possible to convert one element into another by various processes that are classified as nuclear reactions. For example, there is a type of nuclear reaction called nuclear decay, which occurs when the nucleus of an element is unstable and releases energy, nucleons, and/or atoms to achieve stability. One special type of nuclear decay is alpha decay which occurs when an atomic nucleus decays into another one by releasing an alpha particle. Note that an alpha ... Read More

Artificial Transmutation Uses

Updated on 05-Feb-2024 16:36:11

Introduction Artificial Transmutation is the process in which one element changes into another element in decay artificially. This conversion may be natural or artificial. In Artificial Transmutation one element is changed into another element by bombarding fundamental particles like an alpha particle, proton neutron, deuteron, etc. An unstable nucleus undergoes the natural transmutation process but in artificial transmutation, the atoms of the element are encountered with the fundamental particle and form a new element in the decay process. Now let's understand all the terminology related to the artificial transmutation in detail in this article. What is Artificial Transmutation? Transmutation ... Read More

Electric circuit and Electrical Symbols

Praveen Varghese Thomas
Updated on 05-Feb-2024 16:39:46

Introduction Electric circuit and electrical symbols are important to understand to design any electrical or electronic instrument. The branch of physics that deals with the behavior of electrons using electronic circuits are called electronics. The components used in the electronic circuits are active devices and this is the difference between classical electrical engineering and electronics. Electronics has many branches. Vacuum tubes play a vital role in the electronics field. It is the first and basic of electronics that is used to control the movement of electrons. Then IBM transistors take the place of vacuum tubes. Due to some ... Read More

Direct Current Generator

Praveen Varghese Thomas
Updated on 05-Feb-2024 16:41:43

Introduction Direct current generator produces electric current by the process of electromagnetic induction. The electromagnetic force gives rise to the electromagnetic field. In an electromagnetic field, the electric field and the magnetic field are intertwined. Electromagnetic force determines electromagnetic phenomena. Electromagnetic force is the interaction between charged particles. Lorentz's force is also known as the electromagnetic force. The electromotive force refers to the amount of work required by a battery pack to move charged particles through an electrical circuit. An electromagnetic field is a natural field caused by the motion of an object which is electrically charged. It affects ... Read More
