Hiroshima Day And Nagasaki Day Quiz by RNTalks
Two nuclear bombs were released by the United States over Hiroshima and Nagasaki during World War II, respectively. These days are remembered to promote peace and spread awareness about the danger of nuclear energy and nuclear weapons.
A total of 129,000 to 226,000 people were killed, most of them civilians, in the two bombings, which remain the only nuclear weapons use in armed conflict. During the end of the Second World War, the Allies demanded the unconditional surrender of the Imperial Japanese Army in the Potsdam Declaration on July 26, 1945, or they would be destroyed by “prompt and utter destruction”.
The ultimatum was ignored by Japan. As required by the Quebec Agreement, the United Kingdom gave consent to the bombing, and orders were issued to use atomic bombs against Hiroshima, Kokura, Niigata, and Nagasaki on July 25. Take this Hiroshima Day and Nagasaki Day Quiz by RNTalks and learn new facts and understand why Hiroshima Day And Nagasaki Day are observed.

Japanese Emperor Hirohito broadcast a surrender message to his people on the radio. The broadcast came one day after Japan told the United States and its allies that it was surrendering, and Hirohito and Japanese ministers signed the Imperial Rescript of Surrender.
Nagasaki’s bombs contained what type of fissionable material?
Uranium and plutonium are the two main components of nuclear weapons. In order to make a nuclear weapon, one requires highly enriched uranium (HEU) and weapon grade plutonium. The fission bomb dropped on Nagasaki in August 1945 Fat Man used Plutonium−239 as the fissile material.
What was the weight of the Fat man atomic bomb?
The 'Fat Man' atomic bomb was 128 inches (3,300 mm) long and 60 inches (1,500 mm) wide. The weight of the bomb was 10,300 pounds (4,700 kg). Due to its wide, round shape, the early design of the bomb is known as Fat Man. Fat Man had a solid plutonium core and was an implosion type nuclear weapon.
Which city was the primary target during the 2nd bombing on 9th August?
B-29 Superfortress Bockscar, flown by Major Charles Sweeney, was carrying a plutonium bomb, code-named “Fat Man”. Kokura was the intended target, with Nagasaki as a secondary target in the event of cloud cover making sighting impossible. Kokura was partially obscured with smoke and clouds when the plane reached at 9:44 am (1:44 am Tinian Time). Yahata, a city nearby, had been firebombed on the previous day. Additionally, the steel plant in Yahata intentionally set fire to coal tar containers to obscure target sight. Since the plane had limited fuel, it was not able to launch a bombing attack on visual recognition because of the clouds and smoke. Twenty minutes later, the plane reached Nagasaki at 10:50 am, but clouds again obscured the city. After making several bombing runs without obtaining any visual targets, the crew was forced to drop a bomb using radar due to a lack of fuel. A sudden opening in the clouds allowed them to see the racetrack at Nagasaki, and they detonated the bomb on the city’s Urakami Valley midway between Mitsubishi Steel and Arms Works in the south and Mitsubishi-Urakami Ordnance Works in the north.

Where did the atomic bomb actually explode in Hiroshima?
Approximately 500 feet from the Aioi Bridge, the bomb detonated with the force of more than 15,000 tons of TNT directly over a medical clinic. The reaction caused a blinding flash of heat and light throughout the city, though less than two percent of the bomb’s uranium achieved fission.
Who flew Bockscar carrying the Fat Man atomic bomb to the Japanese city of Nagasaki?
Sweeney died of unspecified causes Thursday at Massachusetts General Hospital in Boston. He lived in nearby Milton, Mass.

What is the biggest difference between a conventional bomb and an atomic bomb?
The majority of the energy in a conventional bomb is released in a blast. On the other hand, atomic bombs release 50 percent energy as blast, 35 percent as heat, and 15 percent as nuclear radiation.
What was the name of the top-secret project to develop the atom bomb?
The development of the atom bomb was ‘The Manhattan Project.’ It was a massive undertaking that brought together the best scientists in the world, along with the top U.S. military minds, to produce the controversial atomic bomb, which was developed out of concern that Hitler was working on a nuclear weapon and was planning to use it.
Which place was the US B-29 bomber plane targeting in Hiroshima?
Hiroshima’s Aioi Bridge is an unusual three-way bridge in the shape of a “T”. The original bridge, built in 1932, was used to aim the 1945 Hiroshima atom bomb because of its distinctive shape and because the bridge was close to the city’s center. Although the atomic blast did not destroy the bridge, it sustained a great deal of damage. Bridge repairs were made following the war, and it served for more than 40 years before replacing it with a new bridge (built as a replica) in 1983. A surviving portion of a floor girder from the original bridge was subsequently donated to the Hiroshima Peace Memorial Museum.
