Over the industrial city of Hiroshima, Japan, August 6, 1945. The second was used over Nagasaki, Japan, August 9, 1945. To this day, they are the only two atomic weapons used in any war.
July 16, 1945 the first atom bomb called "Gadget" was tested in New Mexico near Alamagordo.
The U.S. used atomic weapons on the cities of Hiroshima and Nagasaki which effectively ended the Second World War .
The Atomic Clock was invented in 1949, and is still used today.
On August 9, 1945, the "Fat Man" nuclear bomb was detonated over Nagasaki.
The second atomic bomb used in combat was dropped on Nagasaki.
The second atomic bomb was used on Nagasaki because Japan did not surrender after the first bomb on Hiroshima. The goal was to force Japan to surrender quickly and end World War II.
If you do a quick Internet search for 'Atomic Bomb facts'. The Answer will appear immediately.
The atom of the isotope caesium 133; the definition of second in SI is based on this atom.
== == A distant relative of the man who so famously put the ram in the ram-a-lama-ding-dong. Oh, he put the ram in all right. think it was the same guy who put the bang in the bang a lang a ding dong I'd like to shake his hand, though. He, uh, he made my baby fall in love with me.
Cesium is the chemical element used in atomic clocks to measure a second with high accuracy. Atomic clocks use the natural resonance frequency of the cesium atom to define the length of a second. This level of precision allows atomic clocks to keep time accurately to within one second in several million years.
The last atomic bomb used in combat was on August 9, 1945. Many more were dropped from airplanes or otherwise detonated in test shots.
Cesium atoms are commonly used in making atomic clocks, as they are extremely consistent in their oscillation frequencies. By measuring the vibrations of cesium atoms, atomic clocks can maintain extremely accurate timekeeping, losing only about one second every 300 years.
This is the date the vehicle was first purchased and used by the original owner, which means when the vehicle was bought NEW and not when the second owner bought it used.
Atomic fuel is used for producing electricity. It is also used for producing atomic weapons.
Cesium is used to make very accurate atomic clocks. The oscillation frequency of radiation emitted by cesium-133 atoms is used to define the second in the International System of Units (SI).
