How many times stronger a H-Bomb is stronger than atom Bomb?
You are confused, a nuclear bomb is a general name covering both "atomic bomb" and "hydrogen bomb".
A hydrogen bomb is typically higher yield than an atomic bomb, although it is possible to design very small low yield hydrogen bombs for special purposes that have lower yield than "typical" atomic bombs.
However for "typical" hydrogen bombs their yield is roughly 1000 times the yield of a "typical" atomic bomb.
What if Cuba attacked US with those missiles?
At the time of the crisis none of the missiles with nuclear warheads that could reach US territory had yet been installed, so Cuba could not have attacked with them.
However unknown to the US there were active short range missiles with nuclear warheads already installed, had Kennedy ordered the invasion of Cuba suggested by his generals Cuba would have defended itself by attacking the troops as they landed on Cuba's beaches with these short range missiles with nuclear warheads. The US was not prepared for this and the only likely response would have been an all out bombing of both Cuba and the USSR with strategic nuclear bombers, which would have triggered a retaliation by the USSR with their strategic nuclear bombers. It would have been total nuclear war between the US and USSR.
What happened to soviet nuclear weapons after the cold war?
Most are still in Russian hands. The Ukraine got some. The remainder have disappeared and have not been satisfactorily accounted for.
Is a hydrogen bomb the same as nuclear fusion?
Yes and no:
- nuclear fusion makes hydrogen bombs possible
- an actual hydrogen bomb is a rather complex device, involving both nuclear fission and nuclear fusion triggering each other in a precisely timed sequence. Most hydrogen bombs derive 90% of their yield from nuclear fission, almost all of this is from fission of uranium-238 in the tamper around the last fusion stage caused by high energy (15 MeV) fusion neutrons.
Hydrogen bombs operate on a fission-fusion-fission sequence. The full process of a typical modern hydrogen bomb goes something like this:
- The X-Unit (master timing controller) fires 32 detonators on the explosive lenses of the fission primary stage.
- The explosive lenses create an implosion shock wave which crushes the hollow tritium gas filled sealed pit made of plutonium to about 1/3 its normal size (about 27 times its normal density and very supercritical).
- The X-Unit fires the electrical neutron source (a miniature particle accelerator accelerating tritium ions). The fusionof these tritium ions fires neutrons through the supercritical plutonium core.
- Fission begins in the primary stage core.
- When the compressed tritium gas in the sealed pit inside the primary core is heated enough by fission, fusion begins in the center of the primary stage core.
- Neutrons from the tritium fusion in the center of the primary core "boosts" the fission of the plutonium of the primary core.
- X-rays from the primary stage travel through the radiation channel from the primary stage to the cylindrical secondary stage and down its length.
- The x-rays cause a radiation implosion of the secondary stage, compressing it rapidly to very high density.
- Neutrons from the primary stage travel to the "sparkplug", a rod of plutonium in the center of the secondary stage and running its length, which by this time the radiation implosion has compressed to supercriticality.
- The "sparkplug" fissions, emitting neutrons into the lithium deuteride layer of the secondary around the "sparkplug". The lithium captures these neutrons and produces tritium, resulting in a deuterium tritium fusion fuel mix.
- The "sparkplug" continues fissioning, pushing out against the radiation implosion. This combined inward and outward pressure compresses and heats the deuterium tritium fusion fuel mix until fusion begins in the secondary stage.
- High energy (15 MeV) neutrons from the secondary stage fusion cause fission in the uranium-238 tamper surrounding the secondary.
How many fissions and fusions was that now?
Where was India's first nuclear bomb exploded?
India's first nuclear test on May 18, 1974, described by the Indian government as a "peaceful nuclear explosion." The first Nuclear Test in India was cnducted on 18 May , 1974 at Pokhran.
What would be the blast radius of a 200 megaton nuclear bomb?
Well i did some rough estimates...prob be like 56 miles
A blast radius is equal to the square root of the megatonage. A 1 megaton bomb has a blast radius of severe damage of about 4 miles. Therefore a 200 megaton bomb (14 being about the square root) would have about a 56 mile radius. Though direct exposure to the explosion at that distance could probably still cause severe burns and it would probably cause damage as much as 200 miles out.
Why was the hydrogen bomb dropped in 1952?
wefwefwefwefewfewfewf
it let America know what sort of thing they would get into if they did drop it on Japan. It also gave America a false sense of pride, too much pride.
the significance of the creation was that it was the first time humans had easy ability to end civilization
What makes an atomic bomb go off?
The detonation is caused by bringing together a "critical mass" of radioactive material (the term "critical mass" refers to that quantity of material sufficient for a self-sustaining fission reaction).
What triggers this can vary, depending on the intended usage of the bomb itself. It may be set with a barometric or proximity fuze to detonate in the air, an impact fuze to detonate upon, well, impact, a timed fuze to detonate at a particular pre-set instant, or any of the various other types of artillery fuzes.
The hard part is holding that critical mass together long enough for it to fully fission. The warhead tends to blow apart due to prompt dispersal, causing incomplete detonation. High technology is used to form an focused, explosive, compression that will last long enough, even under the intense pressures of super prompt criticality, to make the most of the weapon.
Can nuclear war be a just war?
Of course.
Atomic weapons are just another form of armament.
I am sure that those on foot in 2000 BC didn't think it fair that others had chariots. Probably those that had bronze and wooden swords felt steel swords should be outlawed in the middle ages.
Atomic weapons probably kept Western civilization alive during the 1940s and 1950s when the greatest threat to world culture, the Soviet empire, was expansionist.
Willing as they were to expend millions of lives in conventional war, the Soviets would have been practically unstopable by the casualty squeamish American forces (for evidence note the incredible hand wringing over 2,000 military dead in over two years of combat and occupation in Iraq, a veritable drop in the bucket considering what is at stake). Atomic bombs and the American edge in that weapon kept the Soviets at bay through the 1950s until the other western nations could recover from WWII in the 1960s.
Another viewpoint: I will assume that you are also concerned about the use of the bomb on Japan in 1945. My strong opinion is that the use of the bomb shortened the war and saved Japan from far worse destruction, not to mention almost certain occupation by Soviet forces (read how they treated eastern Germans for a hint on what would have happened in Japan). Thank Goodness the bomb was ready by August 1945 and not a year or so later.
answerthe fist time? yepbut the use of them again? hell no. that would start ww3. even with the it is our goal to deture there use, not incite it
no means of death will be ever justified and there will always be new technologies for this reasons.
Did the Soviet Union have nuclear missiles aimed at US in the cold war?
Yes they did. The US had missles pointing at the USSR, the USSR had missles pointing at the US, and everybody else didn't know what too do.
Can a more powerful bomb be created than the tsar bomba?
Absolutely, Edward Teller developed plans that were never built for a 10GTon h-bomb.
The Tsar Bomba itself was designed for 100MTon yield but then only tested with enough fuel in the casing for roughly 50MTon yield. Why test at full yield when all you really need to prove is capability of ignition.
Why US dropped nuclear bomb japan?
It was the fastest way to end a very brutal war with the least number of Allied casulties.
The alternative was to actually invade Japan itself with troops.
(By this time, Germany had already surrendered and V-E Day had already occured.)
The war in the Pacific was different than the war in Europe, and the Japanese approached military duties in a different way. In fact, Japanese officers would beat up their own soldiers during training.... get them into a battle, and they would either fight or be killed... they didn't believe in surrender. Thousands of Filipino and American soldiers were killed. It wasn't a "we'll trade you for an officer and a few soldiers" kind of war.
The total energy released in a nuclear explosion is the explosions?
That is both hard and simple to answer.
The hard part is based on the fact that it depends on how much of the fuel is converted and on whether it is converted by fission or by fusion. Very few nuclear detonations use anywhere near close to 100% of the fuel. Also, some of the energy goes to subsequent reaction such as to continue the fission reaction in an A-Bomb, and to initiate the fusion reaction in an H-Bomb.
The simple part is based on Einstein's famous equation e = mc2. In this formula, Einstein clarified mass-energy equivalence by stating that a certain amount of mass could be described as the equivalent energy by multiplying it by the speed of light squared. So, in the case of a nuclear detonation, if one kilogram of mass was lost in the reaction, then about 8.99 x 1016 kg m2 s-2 (joules) of energy (or about 21.5 megatons of TNT equivalent energy) would be released, some of which would be lost in sustaining the reaction, most of which would be actually released.
The detonation over Hiroshima, Japan was estimated to represent about one gram of mass loss, which translates to about 1 one thousandth of that, or about 21.5 kilotons of equivalent TNT energy.
To put that into perspective, it is estimated that the Sun loses 0.7% of the mass of 6.2 x 1011 kg s-1 during fusion of hydrogen into helium, producing about 9.192 x 1010 megatons of TNT equivalent energy per second. Our reactors and bombs are just "playthings" in comparison to the Sun - and our Sun is small in comparison with many others!
Why was the nuclear arms race dangerous?
Nuclear weapons are dangerous because they have not been around long enough to see the long term effects. They also may release many toxic chemicals.
Why does the damage continue after the explosion of a large atomic bomb?
Damage to structures continues as fires started by the heat of the explosion grow and spread. People continue to fall ill and die due to radioactive fallout.
How much hydrogen is in a hydrogen bomb?
there is no Hydrogen in a hydrogen bomb.
its called a hydrogen bomb because there are isotopes of hydrogen: tritium (3H ), and deuterium (2
H,)
When were cruise missiles first tested?
The first cruise missiles were the German V-1 used in WW2 against Britain.
How many nuclear bombs does it take to blow up the Earth?
Nobody has ever had enough bombs to blow up the earth! The figure that there are enough nuclear weapons to kill everybody on the earth 10, 20, 50, or however many times over is an entirely different issue (and is very speculative). It may have been true in the middle 1980s at the peak of the arms race, but since START was signed total number of weapons have fallen continuously.

Was there nuclear fall out from nagasaki?
Yes, on August 9, 1945, three days after Hiroshima was bombed.
It was a different type of bomb from Hiroshima though. The bomb dropped on Hiroshima was made by splitting uranium atoms, and was nicknamed Little Boy. However, the bomb dropped on Nagasaki was plutonium. It was nicknamed Fat Man and was the same type as the first A-bomb tested at Alamogordo, NM.
How did the Americans react to the threat of nuclear war?
American citizens during the 1950's experienced the "Red Scare", a public worry about the Soviet Union unleashing war on the United States. Once the Soviet Union proved that they could also develop a nuclear weapon, American confidence contunied to drop, until the United States put the first men on the moon
Why is a fission bomb needed as part of an hydrogen bomb?
Yes, in two or three places depending on the design used:
- the atomic fission bomb primary
- the plutonium sparkplug rod that runs through the center for the length of the secondary
- if present the uranium tamper that surrounds the secondary inside the hohlraum, if a material other than uranium (e.g. lead, tungsten) is used for the tamper then no fission happens in it
If additional stages (e.g. tertiary, quaternary,...) are present in the design, repeat numbers 2 and 3 for each additional stage to get all the places that fission is used.
Where did the US launch the first atomic bomb?
The first atom bomb used in combat was dropped on Hiroshima, Japan on August 6, 1945, but the first one the US ever set off was dropped at the Trinity test site in New Mexico on July 16, 1945.
Why was the nuclear bomb invented?
The US, working with the British, developed the atomic bomb, as it was then called, because it was believed that Nazi Germany was well on the way to making one and it was necessary to be able to match them if they began to use, or threatened to use, such a weapon.
As it turned out, the Germans had not been able to overcome technical as well as political problems and were never near to construction of an atomic bomb. Germany surrendered before the American/British effort had been completed.
The bomb, once developed, was used on Japan to bring the Pacific war to a sudden end. While there has been subsequent controversy about whether the bomb should have been used on Japan, at the time there were very few people who were aware of the bomb's existence and capabilities and who thought it ought not to be used. Most of those few thought that a demonstration on an unpopulated location should be made first.
