Why was the atomic bomb significant in world war 2?
It devastated two of Japan's major cities, Hiroshima and Nagasaki, and showed the Japanese that the U.S. were prepared to stop the war by any means. Emperor Hirohito, knowing that he could not win against such technological superiority, agreed to the terms of surrender, effectively ending the second world war.

rachid's Answer . While Allied military leaders planned for invasion, scientists offered another way to end the war. Since the early 1900s, scientists had understood that m…atter, made up of atoms, could be converted into pure energy. In military terms, this meant that, by splitting the atom, scientists could create an explosion far more powerful than any yet known. During the war, Allied scientists, some of them German and Italian refugees, raced to harness the atom. In July 1945, they successfully tested the first atomic bomb at Alamogordo, New Mexico. News of this test was brought to the new American President, Harry Truman. Truman realized that the atomic bomb was a terrible new force for destruction. Still, after consulting with his advisers, he decides to use the new weapon against Japan. Truman warned the Japanese that if they did not surrender, they would face "a rain of ruin from the air the like of which has nerver been seen on this Earth." When the Japanese ignored the deadline, the United States took action. On August 6, 1945 an American plane dropped an atomic bomb, "little boy", on Hiroshima and killed between 80-100 thousand people. Japan still refuses to surrender, so 3 days later, August 9, another American plane dropped "Fat Man" on Nagasaki that killed between 60-75 thousand people. Then on August 14, 1945 Japan surrenders. yes, it was during that war that the two nuclear bombs were dropped over Japan. . yes! .
well one of the main significances was that we were considered one of the main military protecterets of the world becides russia we were considered vey strong. Also all of a s…udden rusia found out we had atomic bombs then they started to learn how to make them to.
Hitler started world war 2 then japan got involved
See: Wikipedia World War II Casualties.
There were two and they were dropped over Hiroshima and Nagasaki named little boy and fat man.
"Little Boy" was the bomb dropped first, on Hiroshima. It was a Uranium bomb, the nuclear material being Uranium-235. The bomb was not "filled" with it - there was only about …140 pounds of U-235. There was a big mechanism inside the 10 foot long bomb. A sphere of the U-235 was fired down a "gun barrel" into the rest of the U-235 inside the bomb by conventional explosives. When the sphere impacted into the rest of the U-235 this compressed the U-235 and critical mass was achieved, initiating the nuclear explosion. The design was not very efficient. Of the 140 pounds of U-235 only about a pound and a half underwent fission, and the explosion was the result of the release of energy from .6 grams, or less than .02 ounces. "Fat Man" was dropped three days later on Nagasaki. It was a Plutonium bomb, the nuclear material being Plutonium-239. It was exploded the way nuclear devices still are - it was an implosion bomb. An absolutely perfect sphere of sub-critical plutonium was placed inside a hollow sphere of high explosives. The high explosives were detonated exactly simultaneously, compressing the sphere of plutonium which brought it to critical mass, initiating the explosion. Again, the design was not terribly efficient. There were thirteen pounds of Plutonium in the bomb, less than three pounds fissioned, and the energy of less than one gram was released, causing the explosion.
Four were completed prior to Japan's surrender: . MK-III, Gadget; tested at Trinity site in NM . MK-I, Little Boy; dropped by the B-29 Enola Gay on Hiroshima . MK-III, Fa…t Man; dropped by the B-29 Bockscar on Nagasaki . MK-III, unnamed; arrived in San Francisco on August 18, returned to Los Alamos The US had production plans to make 20 more in 1945 if Japan had refused to surrender: . 3 MK-III in September . 3 MK-III in October . 7 MK-III mod 1 in November . 7 MK-III mod 1 in December
in japan the cities Hiroshima and Nagasaki
Those were the only atomic bombs used against mankind. The one named Little boy was dropped over Hiroshima on august 6 1945. The one name Fat man was dropped over Nagasaki on …august 9 1945. With those events, the war ended.
yes, in a way, it was not directly after the dropping that it was over but the Japanese surrendered after that.
Out of the two bombs, one was dropped Hiroshima and the other over Nagasaki.
Because at the time only US had them & were prepared to drop 50 more if needed. 1 of those was equivalent to a full week of bombing runs. The Emperor was not about to let his …country be completely destroyed. Tokyo was only saved because rain was predicted that day. The US wanted to force a surrender since the Japanese were fierce fighters & on their own soil would cost astronomical nos. of American lives.
In World War 2
Because it literally changed history
In World War 2
If you're asking the name it's Fat Man
In World War 2
Only the US, and then only about a month before the war ended.
In World War 2
It ended the war and made possible for the United States to keep lands in the Pacific.
In Japan in WW2
These bombings were not the most significant part of WorldWar Two. However they were certainly spectacular & stunningevents that lead directly to the Japanese decision to su…rrenderunconditionally in August 1945, and avoid the looming Alliedinvasion of the Japanese Home Islands that would have resulted inmillions of casualties and massive destruction.
