Atomic explosions rely on the same principle that generates nuclear energy, which is that the potential energy of matter is equal to its mass multiplied by the square of the speed of light. In the case of most nuclear weapons, this involves the splitting of a uranium atom, which unleashes a massive explosion of energy.Know More
The energy of an atomic bomb is released in the form of heat, and the sudden expansion of that wave of heat ignites the air around it, which results in a colossal fireball and the release of toxic levels of electromagnetic radiation. The original construction of the first atomic bomb began when several European scientists alerted the United States government that Nazi Germany was in the process of refining radioactive materials for use in a nuclear detonation. This began one of the most potentially destructive arms races in human history, which culminated in the destruction of two major Japanese cities.
Years later, the memory of the havoc wrought on Nagasaki and Hiroshima is often what stays the hand of world leaders when the use of strategic nuclear arsenals becomes an option. To date, no other nuclear strike has been made by any other country, and while many nuclear arsenals have been reduced, the threat of the use of nuclear weapons remains.Learn more about Physics
The moment of inertia of a solid cylinder is equal to one half of the mass multiplied by the square of the radius. This equation should be used to find the cylinder's moment of inertia with respect to the z-axis, or the plane parallel to the cylinder's height.Full Answer >
Atomic energy, also referred to as nuclear energy, is used to generate electricity, and has applications in the fields of agriculture, medicine, research and industry, too. Atomic energy contains highly active radioisotopes, which are various forms of atoms comprised of the same chemical elements. These isotopes share many chemical properties, but have different volumes of relative atomic masses, which makes them suitable for different chemical, electrical, engineering and industrial practices.Full Answer >
Although both atomic and nuclear bombs derive their immense power from reactions that take place in the nucleus of the atom, they do so in different ways. As the terms are most commonly used, an atomic bomb derives its energy from fission, or splitting atoms, while a nuclear device, or "H-bomb," is driven by fusion.Full Answer >
Atomic bombs work by splitting atoms, while hydrogen bombs, also known as nuclear bombs, draw their energy from fusing atoms together. While both types of reactions involve the nucleus of the atom, and both can therefore rightly be called "nuclear," tradition has reserved the word for the types of reactions that are exclusive to fusion devices.Full Answer >
