At 5:30 a.m. on July 16, 1945, Los Alamos scientists detonated a plutonium bomb at a test site located on the U.S. Air Force base at Alamogordo, New Mexico, some 120 miles south of Albuquerque. Oppenheimer chose the name “Trinity” for the test site, inspired by the poetry of John Donne. The test had been scheduled for 4 a.m., but when the time came it was raining, and the appointed hour was pushed back to 5:30. Tensions ran high at the test site, where those assembled included the scientist Enrico Fermi–who had directed the first nuclear chain reaction in December 1942–U.S. Army Brigadier General Leslie Groves, Bush, Oppenheimer and others.
When the bomb was finally detonated atop a steel tower, an intense light flash and sudden wave of heat was followed by a great burst of sound echoing in the valley. A ball of fire tore up into the sky and then was surrounded by a giant mushroom cloud stretching some 40,000 feet across. With a power equivalent to around 21,000 tons of TNT, the bomb completely obliterated the steel tower on which it rested. The nuclear age had begun.
Answer: <em>B. The ironclad
</em>
Explanation:
The main battle between ironclads occurred on 9 March 1862, as the defensively covered Monitor was conveyed to shield the Union's wooden armada from the ironclad smash Virginia and Confederate warships. With the clash of Hampton Roads, maritime fighting changed forever. Ironclads were warships intended to be impenetrable to foe shot and shell by the excellence of their iron-shielded wooden structures.
Different names for these boats incorporate rams, defensive layer clads, iron gophers, iron elephants, iron pine boxes, turtle-backs, and mud-smashers. So incredible were the ironclads that they upset an ancient axiom of naval warfare that forts were stronger than ships.
