The Cotton Gin impacted the American economy by allowing short-staple cotton to become the South's most important cash crop. The reason the cotton gin was so important to the south was because prior to it the south was only able to produce tobacco and long-staple cotton which was easier to grow and clean; however, after the invention of the cotton gin the South was able to grow and clean short-staple cotton much faster than before and thus able to turn this once unprofitable raw good into it's most import cash crop.

Answer:
The reason is that, despite the distance, most objects / stars in the night sky, are not really that small, but appear very large.
Explanation:
While magnification in telescope helps to enlarge the object of focus, it is however, not always a good thing when doing astronomical viewing, due to the following reasons:
1. With higher magnification, a bigger object may not fit into the view, as a result of the total field view becoming smaller. For example, it will be easier to see the whole Andromeda galaxy on a small or low power view than on higher magnification.
2. Since most objects or stars in the sky are not so bright, applying higher magnification will make them look dimmer than necessary, thus will be difficult to observe. For example, during observation of Orion Nebula, it will be difficult to observe the body, if the telescope is magnified than necessary.
3. The presence of atmosphere or atmospheric conditions on earth also affects the telescope or magnification, as a clear and steady atmosphere helps the imaging of telescope to be sharp, while the unclear and turbulent atmosphere makes the imaging to be less detailed.
Answer:
after two days
Explanation:
April 6, 1917: Two days after the U.S. Senate voted 82 to 6 to declare war against Germany, the U.S. House of Representatives endorses the declaration by a vote of 373 to 50, and America formally enters World War I.
When World War I erupted in 1914, President Woodrow Wilson pledged neutrality for the United States, a position that the vast majority of Americans favored. Britain, however, was one of America’s closest trading partners, and tension soon arose between the United States and Germany over the latter’s attempted quarantine of the British Isles.
Several U.S. ships traveling to Britain were damaged or sunk by German mines, and in February 1915 Germany announced unrestricted warfare against all ships, neutral or otherwise, that entered the war zone around Britain. One month later, Germany announced that a German cruiser had sunk the William P. Frye, a private American vessel. President Wilson was outraged, but the German government apologized and called the attack an unfortunate mistake.
