Atomic Bombs
Atomic bomb is an explosive device in which a large amount of energy is released through nuclear reactions. This makes an atomic bomb, more properly called a nuclear weapon, a much more powerful device than any conventional bomb containing chemical explosives. The first Atomic Bombs were used during World War 2 in 1945 by the US onto 2 Japanese cities.

Why was the USSR afraid of the US atomic bombing Japan?
Please remember that by the time the US dropped the A bombs on Hiroshima and Naggasaki, the war in Europe was over. The Soviets had gathered as much technology from Germany as they could. They knew where Germany's research efforts were leading them. Also remember at this time Patton was trying to regroup and re-equip the former Germans into units he could train for the drive against the Soviets. Patton had asked the valid question, why did we fight and have so many Americans die to replace one dictator (Hitler) with another (Stalin). The Soviets knew about Patton's remarks and that there were some in the Allies camp who wanted to continue the war. With the dropping of the A bombs, the US displayed a new and fearsome weapon against which the Soviets had no defense.
How did they keep the atomic bomb secret?
The Japanese did not actually dodge our radar sensors when they bombed Pearl Harbor. At the time of the attack there were only mobile radar stations in place, no fixed radar stations were able to be built because of dissent in the government planning of the structure. Because there were only mobile radar stations they could only be operated during certain time frames due to the fact they were needed for maintance and training. On Sunday morning they were supposed to shut down at 7:00 however because the operators ride had not come he kept it running. At 7:02 he spotted the formation of the Japanese. After plotting their course and other necessary information he called his superiour who disregarded the information. He had disregarded the information because he took it for the flight of B-17's(i think?) that were supposed to arrive a couple minutes later and 5 degrees from the formation's location. He had also heard hawain music played in the morning which was oftened used to allow there planes to home onto the islands. Because of these unfortunate events the Japanese were able to penetrate our radar sensors.
What city scientists did research for the atomic bomb?
The name of one of the projects for developing atomic weapons during WW2 was "The Manhattan Project". Presumably the name was derived from the city in which the project was carried out.
Why should the atomic bomb be kept a secret?
Although the USSR was officially our ally we did not really trust them because they were communist. However many of the scientists and technicians on the Manhattan Project were communist spies and kept the USSR fully informed on practically everything about the atomic bomb.
After World War 2 ended what effect did the development of the atomic bomb have on the world?
That started the Cold War. at it's end mutual destruction was assured
Is an atom bomb the same as an atomic bomb?
Atomic bombs use nuclear fission to cause near perpetual chains of reactions. Nuclear warheads (Nukes) just sums up all the different types, including hydrogen bombs (which use nuclear fusion, a much more potent type of power) and atomic bombs. So yes, they are the same.
How did the Atomic bombs dropped by the United States on Hiroshima and Nagasaki effect the economy?
After the attack, the japanese had no means to recover. It took 15 years for the US to rebuild japan.
How were the Japanese warned of the atomic bombs?
Truman issued the "Potsdam Declaration". Truman was at the Potsdam Conference, near Berlin in defeated Nazi Germany when he was informed that the prototype bomb had been exploded successfully July 16. About two weeks before Hiroshima, he made the "Declaration", calling on Japan for immediate unconditional surrender, promising that if they did not immediately surrender they would face "prompt and utter destruction", "the like of which the world has never seen". The words" Atom Bomb" were not used. Very few knew what an Atom Bomb was outside university physics departments, and this would have tipped off the Japanese to try to shoot down every single B-29 appearing overhead. The Japanese had gotten to the point of ignoring bombers appearing in ones and twos, thinking they were weather scouts for later mass raids.
The Japanese made no reply to the "Potsdam Declaration". A sticking point for the Japanese was the "unconditional" surrender - they wanted to keep the Emperor, whom they had been taught to believe was a living god.
Why didnt the US use the atomic bomb Germany?
The atomic bomb wasn't tested till July 1945 - two months after the war with Germany was over. Also, I believe that the use of the Atomic Bomb was considered very risky. Americans had close ties to Europe and they did not want to totally destroy the German land and culture. Another consideration is that there were probably more Allied being held as prisoners in Germany than being held in Japan. So, as was the case with the bombing of Nagasaki, there would be a risk of killing some of your own soldiers who were being held as prisoners of war.
Who decided to drop an atomic bomb on a Japanese city?
President Harry S. Truman personally made the decision to use the atomic bombs on Japan, a decision that effectively ended World War 2, saving millions of civilian and military lives.
How close was Japan to using atomic bombs against the US?
Japan was nowhere near even having the technology or resources to think about it.
AnswerI've read some about this and the Japanese had made remarkable progress in understanding the atom and theoretical possibilities concerning a bomb. However their program was operating on a shoestring (as I recall only 3 or 4 scientists had any involvement) and the resource base was lacking. It is conceivable that given another year or two, with decent funding, the Japanese might have developed a bomb. Delivering it to the USA would have presented a whole new set of problems.Germany on the other hand, had a much more advanced A bomb program although it too was not funded adequately - I'd suggest that was largely due to the demands of the eastern front that was consuming 80% of Germany's war economy output. That, combined with rampant 'creative incompetence' among many in the scientific community, meant that Germany too, was blocked from having an effective weapon by war's end. However - Germany did possess the wherewithall to put out a 'dirty' bomb that could have rendered major urban areas uninhabitable. It was, obviously, never completed.
AnswerNeither Japan nor Germany had an effective nuclear weapons project during WW2.
Germany was the closest, with a reasonably advanced research project staffed by a small (but very highly educated and competent) staff of highly respected physicists. However, their original assessment of the difficulties in building a bomb was that no country would be able to complete it until the very late 1940s at the earliest. Additionally, the Allied powers embarked on a program of systematically destroying key components that the German nuclear program needed to make progress. By the end of the war, Germany had merely managed to build an atomic pile, the precursor to building an actual reactor. They were nowhere near having a completed design, and didn't have any of the industrial infrastructure to produce nuclear fuel. It is doubtful that Germany could have built even a "dirty" bomb.
Japan was in an even worse state. They had very few nuclear physicists (and none of the intellectual stature of the Germans), and a large amount of their nuclear technology and nuclear fuel came from Germany. The Japanese nuclear program suffered from a complete lack of funding, too. They hadn't even managed to get a nuclear pile running by 1945, and had very little nuclear fuel available for experimentation. It is pretty much a flight of fantasy to assume that Japan could even have produced a dirty bomb, and likely would never have developed an atomic bomb themselves for a decade or more.
So, the answer to the question is: Japan had no possibility of using an indigenously-developed atomic bomb against the US during WW2.
How loud was the atomic bomb when it hit hiroshima?
a bomb is louder than you think it is it's about million times bad than you still think it is
Love, Bryce who's a kid (who's a girl) and is 9 years old!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
What statements correctly describes the destruction the atomic bomb caused at Hiroshima?
lots of weed
Why was president Truman's reason for the use of the atomic bomb accepted?
The US had been at war with Japan for 5 years, having been attacked by Japan. The US had come close to losing to Japan several times. Japan had refused to surrender. The bombs ended the war. To have invaded Japan with conventional forces was estimated to cost the lives on nearly 1 million Allied soldiers, and many more Japanese.
What was the Atomic bomb that hit Japan in World War 2 like?
The atomic bombs where the last attacks in World War 2. A uranium gun-type atomic bomb (Little Boy) was dropped on Hiroshima on August 6, 1945, followed by a plutonium implosion-type bomb (Fat Man) on the city of Nagasaki on August 9. The first atomic bomb ever to be used in a military operation was dropped on the city of Hiroshima, Japan On August 6, 1945 at 8:16:02 a.m. Hiroshima time. The bomb, affectionately named "Little Boy," exploded 1,900 feet above the courtyard of Shima Hospital, with a force equivalent to 12,500 tons of TNT. The second bomb, called "Fat Man," exploded over Nagasaki, Japan, at 11:02 a.m. on August 9, 1945. It exploded at 1,650 feet with a force of 22,000 tons of TNT. 70,000 people lost their lives in Nagasaki by the end of 1945 due to the bombing. A total of 140,000 died within the next five years.
Negative effects of atomic bombs in history?
There were only 3 atomic bombs in history (that we know of), two of which were used against civillian people. Jumbo, was tested in Alamagordo, New Mexico, and it proved that atomic weapons could be made. Little Boy was the name of the Atomic Bomb that destroyed Hiroshima. Fat Man was the name of the Atomic Bomb that destroyed Nagasaki.
Negative effects of these atomic bombs were pretty obvious.
First, Japanese people died. About 240, 000 Japs were killed from both bombings.
Second, both areas were filled with lasting radiation, making each place uninhabitable for a long period of time.
Third, these bombings might have been one of the immediate causes of the Cold War, but this can be debated, as there are other more important reasons...
What are three disadvanatges to using the atomic bomb?
The atomic bomb has advantages and disadvantages and sometimes they are the same thing.
- The cost of building, housing, maintaining and guarding an atomic missile bomb is astronomical.
- The dangers involved in accidental radiation is minimal but still there. If the bomb is set off radiation is a definite problem around the world.
- The bomb can destroy cities and small countries all at once. (also advantage) But, retaliation is possible. You can end up destroying the world.
- The consequences of the bomb's afterlife radiation takes 50 to 100 years or more to wear out depending on the amount of bombs dropped.
The SECOND nation to test an atomic bomb was?
The USSR was the second country to test a nuclear weapon. The testing happened on August 29th 1949 with a bomb called RDS-1 (Reaktivnyi Dvigatel Stalina) in reference to Joseph Stalin.
What did they build the atomic bomb for?
Atomic bombs were used by the US against Japan at the end of World War II.
Once nuclear physicists and military leaders became aware of the application of nuclear fission for a weapon, it was decided to build atomic bombs, if only to counteract their development by Germany and the Axis. As things turned out, the Germans developed rockets, but never built a nuclear bomb for use with them. By the time the US had its bomb (July 16, 1945), Germany had been defeated without it, and it was used instead as intimidation against the last struggling war efforts of the Japanese.
Rather than invade Japan, the US dropped two atomic bombs on Japanese cities, and implied that they had many more to use (in fact, they had no more, and could only build about two a month). With Japan's anti-invasion plans rendered useless, the Japanese surrendered six days after the second bomb was dropped (Hiroshima on August 6, and Nagasaki on August 9, 1945).
Were both atomic bombs the same day?
No, Little Boy was dropped on Hiroshima on August 6, 1945, and Fat Man was dropped on Nagasaki on August 9, 1945. Little Boy was the first atomic bomb to be used during warfare.
What are the advantages and disadvantages of The dropping of Atomic bombs?
There were pros and cons to detonating the atomic bomb on Hiroshima, the Empire of Japan. President Truman weighed the pros and cons with the help of three teams: expert scientists, civilians, and soldiers. All agreed, however, that the United States should detonate the bomb (nickname: Little Boy) in Japan. If not, it was estimated that WWII in the Pacific Theater would last at least another ten years with the cost of many, many American lives. Detonating Little Boy would ensure that no more lives be lost in the war, Japanese, American, civilian, or military. On the other hand, Little Boy's power was not known, and could murder more people than ever imagined.
Did president Truman approve the use of the atomic bomb?
Truman did inform the Japanese about the atomic bomb attacks by instructing the military to drop leaflets throughout the country. It is disputed that Hiroshima, one of the cities that suffered the worst from these attacks, were never informed of this.
Did Adolf Hitler drop a atomic bomb?
If you mean the 2 bombs dropped on Japan in WW2, they were dropped from B-29 heavy bombers using Norden bombsights to visually locate the AP for release. The bombs were released from about 30,000 ft and were radar fused to detonate at between 1,500 ft to 2,000 ft as airbrushes.
Later many but not most of US & USSR test shots were dropped using a wide variety of bombers and fighters on test sites, but most were not dropped at all but were a variety of fixed test shots: on towers, hanging from tethered balloons, surface bursts, barges, underground, etc., a few were rocket launched detonated in space.
