Atomic Bombs

That varies from design to design. The physics package is typically quite small, the chemical explosives can be much bigger depending on the types used.

Albert Einstein did not make an atomic bomb. He was a theoretical physicist who wrote a letter to President Franklin D. Roosevelt warning about the potential of nuclear weapons and the need to develop them, which ultimately led to the Manhattan Project and the creation of the atomic bomb.

An atomic bomb is a type of nuclear weapon that uses nuclear reactions to create an explosive force. It relies on the process of nuclear fission to release a large amount of energy in a very short time, resulting in a powerful explosion. Both atomic bombs and nuclear weapons involve harnessing the energy released from splitting or combining atomic nuclei.

To listen into someone else's conversion. A nicer way of saying you were being snoopy or spying on people while they talk.

The temperature at the center of an atomic bomb during detonation can reach tens of millions of degrees Celsius. This extreme heat is generated by the nuclear fission or fusion reactions taking place, releasing massive amounts of energy in a fraction of a second.

I'm not quite sure what you mean as "progress". It appears to be a technology that somebody would have developed sometime in the timeframe of the 1940s, 1950s, or 1960s, even if WW2 had not accelerated the "need" for it. The idea of the neutron chain reaction required for it had already been patented in 1934 by Leo Szilard and the Uranium fission reaction needed to make it work had already been discovered in 1939 by Otto Hahn. The main thing that limits it is the specialized industrial infrastructure that needs to be developed to prepare the components. However it has more or less been shown that for a country sized entity, this takes roughly 4 years from decision to proceed to ability to make bombs.

You mean what triggers the fission chain reaction?

The atomic bomb that was dropped on hiroshima was a gun style fission bomb that used a uranium-235 core. The core consisted of two hemispheres of U-235 on each side of a tube, with an explosive that would push them together. When they collide, they reach the critical mass for an uncontrolled chain reaction and nuclei start to split and release neutrons which will collide with other nuclei and split them as well. The explosive used to trigger the reaction is triggered by a detonator.

The race to build more atomic bombs between the US and the USSR during the Cold War was called the Arms Race. It was a period of intense competition and escalation of nuclear weapons development between the two superpowers.

Albert Einstein did not personally work on the atomic bomb project. However, his theories on relativity and mass-energy equivalence, particularly the equation E=mc^2, laid the foundation for understanding the energy released in nuclear reactions, which was crucial for the development of the atomic bomb by other scientists and engineers during the Manhattan Project.

The main difference between atomic bombs and hydrogen bombs is the source of their energy. Atomic bombs rely on nuclear fission (splitting atoms), while hydrogen bombs use a two-stage process involving both fission and fusion (combining atoms). Hydrogen bombs are more powerful and destructive than atomic bombs.

Albert Einstein did not work on the Manhattan Project, the US efforts to develop the atomic bomb. He was denied sufficient security clearance to do so. He did however write a letter to President Roosevelt, composed by his friend Leo Szilard, who did work on the project. Einstein was a teacher.

Approximately 15-25 kg of highly enriched uranium or 6-8 kg of plutonium is typically used in a 100-kiloton bomb. These materials undergo a fission chain reaction to release a huge amount of energy in a nuclear explosion.

The key scientists involved in the development of the atomic bomb during World War II were J. Robert Oppenheimer, Enrico Fermi, and Leo Szilard as part of the Manhattan Project led by the United States. These scientists played crucial roles in the theoretical and experimental work that led to the successful creation and deployment of the first atomic bombs.

If you are asking specifically about the two bombs dropped on Japan in WW2, they were fuzed for airburst, so they did not hit the ground. Both exploded between 1500 ft & 2000 ft altitude. Airburst was selected to maximize blast & thermal flash damage effects area.

The atoms in the atomic bombs used on Japan were atomic size. The size of the atom depends on what element or ion we're talking about. As for the bombs themselves, the Little Boy had a yield of about 12 to 14 kilotons, and Fat Man had a yield of about 20 kilotons.

J. Robert Oppenheimer, the first director of the Los Alamos Laboratory and a key figure in the Manhattan Project, which developed the atomic bomb, was American.

To get WW2 to end. The Japanese emperor knew that to surrender would be a dishonor, so we decided that if he didn't want to surrender, we would just start wiping out tens of thousands of his people at a time, which we did twice with two nukes. So, for the sake of his people NOT getting nuked a third time, not his family, he surrendered.

The first atomic bomb was developed during World War II as part of the Manhattan Project, which involved many scientists, including J. Robert Oppenheimer, Enrico Fermi, and Leo Szilard. The project was led by the United States and also involved collaboration with scientists from other countries.

While the atomic bomb was not made in Oak Ridge, Tennessee, the uranium used in the bomb was enriched at the Oak Ridge facility as part of the Manhattan Project during World War II. Oak Ridge played a significant role in the development of the atomic bomb by providing the enriched uranium needed for the bomb's construction.

Albert Einstein is best known for his theory of relativity, which revolutionized our understanding of space, time, and gravity. He also made significant contributions to quantum mechanics and the development of the laser.

There are many types of nuclear radiation that have nothing to do with bombs, reactors, etc. In fact most radioactive material on earth was formed in supernovas billions of years before our solar system even formed.

The materials used to make the active components of nuclear explosives are radioactive, however the designers of such explosives state that this radioactivity actually makes it harder to build reliable explosives. This radioactivity causes predetonation fizzles in fission bomb designs and aging/wear-out problems in all bomb designs.

Another problem with radioactivity in nuclear weapons is the exposure hazard to personnel. For example the US Navy uses what is called Super Grade Plutonium, that has much less Plutonium-240 which is a strong gamma emitter than standard weapons Plutonium, in all their weapons that is very expensive to make.

The principles used in nuclear explosives are nuclear fission and nuclear fusion.
