According to Gibbons v. Ogden, a state <u>can not interfere with the power of congress to regulate commerce.</u>
<u>Explanation</u>:
The case of Gibbons and the Ogden was presented in the Supreme Court in the United States of America. It was in the year 1824 and was one of the most important cases of that time.
According to this case, a principle was established and it established a legislative enactment. According to this, a state could not interfere in the power of the congress and the power that was talked about in this principle was about interfering with the regulation of the commerce. It was only in the hand of the congress and not with the states.
This is Hiroshima. The bomb that was used was the Atomic Bomb. It should be "B", because everything was completely destroyed besides the building shown in the picture.
Answer: Marie Curie studied the radiation of all compounds containing the known radioactive elements, including uranium and thorium, which she later discovered was also radioactive. She also found out that:
- you can exactly measure the strength of the radiation from uranium;
- the intensity of the radiation is proportional to the amount of uranium or thorium in the compound - no matter what compound it is;
- the ability to emit radiation does not depend on the arrangement of the atoms in a molecule; it must be linked to the interior of the atom itself - a revolutionary discovery!
When she realized that some uranium and/or thorium compounds had stronger radiation than uranium, she made the following hypothesis: there must be an unknown element in the compound which had a stronger radiation than uranium or thorium. Her work aroused the interest of her husband, Pierre Curie, who stopped his own research on crystals and joined the "detective work" with his wife. And Marie was proven right
Assuming your question is in reference to World War I, here's how much of Europe ended up locked in battle:
The systems of alliances and military plans which were put in place before World War I presupposed a major war between the countries which were tied together with alliances. The Triple Entente had Britain, France and Russia as allies. Germany was part of a group of allies in opposition to the Triple Entente. Behind these alliances stood the escalating trend of militarization and military planning that the nations were doing, preparing for war with one another. Militarism was the propelling force that led the nations to think that war was the best way to solve the problems that arose.
So here's what happened to start the Great War (World War I). When an Austrian prince and his wife were assassinated in Serbia, the Austrian Empire threatened the nation of Serbia with retaliatory action (even though the assassination was carried out by a terrorist group, not the Serbian government). Russia responded to Austria's threat, because Russia was bound to protect its Slavic ally, Serbia. Germany responded to the mobilization of Russian troops, and when Germany declared war on Russia in 1914, they implemented the Schlieffen Plan (drawn up by one of their generals), which called for them to go on attack vs. France. That pulled France and Britain into the war immediately as well, and the war spread and became a global conflict.
