The famous 'Mushroom Cloud' is made by a combination of gases and ash. The gases are sulphur, hydrogen, carbon dioxide, carbon monoxide and many more.
which bomb?
Dangerous enough to bring a huge city to ruins.
They killed people in huge numbers and destroyed cities.
When an atomic bomb explodes it forms a mushroom cloud, the explosion gives off EMP or Electro Magnetic Pulse, the explosion is huge and can destroy so much for miles, and the explosion gives off huge amounts of radiation so if you survive the explosion you can suffer or die from the radiation after the bomb blew up.
Leo Szilard invented the atomic bomb in 1933, but no one person can be credited with creating it. Remember the US spent $2,000,000,000 on constructing and operating the huge industrial infrastructure needed to build them before a single bomb could be built!
An atomic bomb codenamed "Little Boy" was dropped on Hiroshima at 8:15 AM on the 6th of August, 1945.
Generally fusion weapons - that's an atomic bomb on the inside that starts a fusion reaction with the material surrounding the atomic bomb. An atomic bomb works by uranium splitting or fissioning. This produces enough energy to cause fusion of the the surrounding material - the atoms fuse or join together liberating lots of energy. The surrounding material is usually the hydrogen isotope - deuterium. However there are apparently fusion weapons that use different surrounding materials that change the nature of the fusion so that it produces huge energy in the form of high-energy neutrons.€ (neutron bomb) These destroy life but not buildings, infrastructure etc. The choice of the surrounding material affects how fast the radio-activity returns to safe levels.
Many countries use atomic energy to generate electricity
One, no it couldn't destroy the whole US, this country is huge. And terrorists wouldn't drop it, they would probably put it in a van and detonate like a car bomb.
It's just the nature of atoms; when atoms fission or split, they release huge amounts of energy. Now multiply the amount of atoms split by the trillions, even by the sepetillions, and you have one explosive device no one wants to have dropped on.
Atomic and nuke bombs are thesame Atoms are very very small but there is alot of energy i them when the bomb explodes the atoms (that are very senciteve) colapse and realise a huge amount of energy. scientists are stiil suprised how so much energy can be stored in so little space
Nobody used or even thought of an atomic bomb for D-Day. D-Day was basically a huge invasion of Allied troops to beat the German Armies in Europe. - The Atomic Bomb came over a year later in Japan ( The opposite side of the world from Europe) and had nothing at all to do with D-Day.- Sounds like someone needs to read their history books !
