Radar and sonar were developed between the two world wars. Describe how these new inventions were used during World War II and their uses after the war.

Answers

Answer 1

Answer:

Radar technology played a significant part in World War II and was of such importance that some historians have claimed that radar helped the Allies win the war more than any other piece of technology, including the atomic bomb.

Sonar on a submarine is very similar. The sub sends out a sound—a ping—which bounces off a nearby object in the ocean and creates an echo that returns to the boat. World War II submarines could stay underwater for up to two days. During that time, sonar operators were hard at work.

Explanation:

Radar was originally developed to detect enemy aircraft during World War II, but it is now widely used in everything from police speed-detector guns to weather forecasting.

Sonar is also used in acoustic homing torpedoes, in acoustic mines, and in mine detection. Nonmilitary uses of sonar include fish finding, depth sounding, mapping of the sea bottom, Doppler navigation, and acoustic locating for divers.

QUOTE

The quote by Voltaire reflects the ideas of tolerance and humanitarianism.

In the quote, Voltaire expresses a commitment to preaching tolerance, or the acceptance of others despite differences in beliefs or practices. He makes it clear that he will continue to advocate for tolerance as long as persecution, or hostile treatment, continues to occur.

The idea of tolerance is closely related to the idea of humanitarianism, or the belief in the inherent worth and dignity of all human beings. By advocating for tolerance, Voltaire is promoting the idea that all people deserve to be treated with respect and kindness, regardless of their beliefs or backgrounds.

The quote also reflects the idea of freedom of thought, as Voltaire is expressing his own thoughts and opinions about the importance of tolerance. He is using his freedom of speech to speak out against persecution and to promote a more inclusive and accepting society.

By 1608, Samuel de Champlain (sham PLAYN), had reached
Canada. There, he sailed down the St. Lawrence River from a
trading post in Tadoussac. A trading post is a type of store

Can someone help me with question

Answers

Answer:

I think Americans at the time felt extremely unsafe, it was already an unsafe time for people of color and minorities. Adding on the fear of a global nuclear war would make anybody horrified, regardless of socioeconomic status. For example, Japanese-Americans located in internment camps would fear for their family and livelihoods ontop of nuclear war. Another example would be caucasian citizens who could fear being accused of espionage or communist activity as well as nuclear war. The cold war was a time where the U.S govt was against everyone, including it's own inhabitants.

The workers in America found their lifestyles changing as the nation progressed industrially. Many of the workers became involved in provision of services rather than production of goods. Farmers on the other hand were in great trouble as the benefits of agriculture lead to consolidations and hence family farms were thrown out of business by the large farming businesses.

There was movement of the Americans from inner cities to suburbs where cheaper hosing was found in order to fit the big families that were as a result of a postwar baby boom. And as the suburbs grew bigger, more businesses were created such as large shopping centers that reduced traffic of shoppers in the cities. New highways were also constructed so as to make the suburbs accessible.There was also the widespread marketing of the television which had been developed previously but not marketed until after the war.

In conclusion, the Cold War was an important historical event. Specifically, it was very important to the Americans as it enabled them to progress economically, culturally and politically. We can therefore say that the United States became even more powerful after the Cold War and up to now it is regarded as the most powerful nation in the whole world.

NO LINKS PLESSEEE

Answers

The correct answer to this open question is the following.

Although there are no options attached we can say the following.

the strengths and weaknesses of the Continental Army

during the Revolutionary War.

Strengths.

At the beginning of the Revolutionary War, there were practically no strengths in the Continental Army. We can mention one, the Patriotism and courage of the colonists that fought for the Continental Army.

As the war advanced, one important strength was that European countries such as France and Spain helped the Continental Army financially and with supplies.

The experience and courage of General George Washington.

Weaknesses.

The lack of money, problems of transportation, and poor organization. Under these deplorable conditions, the Continental army had to use the Quartermaster Department to help solve some problems. It asked the states to provide for supplies. Patriots responding sending blankets, food, and other supplies by the effort was not enough. There was no good communication and organization between the Quartermaster and the government of the colonies.

General George Washington knew the Continental Army soldiers were poorly trained and had minimum combat experience. That is why Washington called the help of Prussian military Official Baron Von Steuben during the winter of 1778 in Valley Forge. This Prussian military really helped to train the American troops.
