Answer:
As a result of the impact of the Great Depression, millions of Americans lost their jobs and saw their lifestyle affected. Practically everybody in the country had to adapt to a different life in those terrible years. In the middle of the USA, besides facing the effects of the depression, farmers also faced droughts; thousands of farmers and their families, with no income and many debts, moved west with the hope to start again. Women had traditional roles at home, but as material difficulties mounted, many women had to look for jobs outside home and sometimes, they had to take jobs formerly done by men, joining the workforce and thus bringing change in that area; though their life was already hard before the depression, African Americans were hit hard, too. They took jobs in dagerous places such as foundries and in dangerous conditions, they took jobs as domestic servants to white people, they were labor for railroad construction, steel mills and coal mines.
Explanation:
The Gulf of Tonkin was a resolution passed by the US Congress during the Vietnamese War. Under this resolution, the Congress gave authority to the President Lyndon Johnson to take necessary action to maintain peace internationally.
This resolution allowed the US to take military action in Vietnam and keep hold of the Southeastern country.
Steam locomotive,because they were built during the Industrial Revolution.Which happen during late 1800's
The submarine became a potentially viable weapon with the development of the Whitehead torpedo, designed in 1866 by British engineer Robert Whitehead, the first practical self-propelled or 'locomotive' torpedo.[20] The spar torpedo that had been developed earlier by the Confederate States Navy was considered to be impracticable, as it was believed to have sunk both its intended target, and probably H. L. Hunley, the submarine that deployed it. In 1878, John Philip Holland demonstrated the Holland I prototype.
Discussions between the English clergyman and inventor George Garrett and the Swedish industrialist Thorsten Nordenfelt led to the first practical steam-powered submarines, armed with torpedoes and ready for military use. The first was Nordenfelt I, a 56-tonne, 19.5-metre (64 ft) vessel similar to Garrett's ill-fated Resurgam (1879), with a range of 240 kilometres (130 nmi; 150 mi), armed with a single torpedo, in 1885.
A reliable means of propulsion for the submerged vessel was only made possible in the 1880s with the advent of the necessary electric battery technology. The first electrically powered boats were built by Isaac Peral y Caballero in Spain (who built Peral), Dupuy de Lôme (who built Gymnote) and Gustave Zédé (who built Sirène) in France, and James Franklin Waddington (who built Porpoise) in England.[21] Peral's design featured torpedoes and other systems that later became standard in submarines.[22][23]
