What were two competing television technologies in the 1920s?

Answers

Answer 1

The two competing television technologies in the 1920s were C. Mechanical vs. optical disk.

During the 1920s, television was in its infancy and inventors were experimenting with different methods to transmit images over long distances. Mechanical television systems were based on rotating disks with holes, known as Nipkow disks, which could scan images and transmit them as electrical signals. Scottish inventor John Logie Baird is credited with developing the first working mechanical television system in 1926. Mechanical systems, while groundbreaking at the time, were limited in resolution and struggled to display smooth motion.

The optical disk technology, while related to television in terms of image storage and retrieval, was not a competing technology for broadcasting at the time. The British vs. American and Russian vs. French options are not relevant in this context, as they refer to nationality rather than specific technological approaches. Therefore, the correct option is C.

What is the legacy and relevance of the Medieval Period to our world today?


(if you do choose to write an essay for the answer that would be soo helpful to me but bullet points that I can use for my essay is okay as well I appreciate all help :))

Answers

Answer:

Today, the period in Europe from about the year 500 through approximately 1500 CE is called the Middle Ages, or the medieval era (the word medieval comes from the Latin medium aevum, literally middle age). But of course people who lived at that time did not think of themselves as being in the middle of anything—they, like we, referred to their own time as “modern.” A seventeenth-century German historian, Christoph Keller, first came up with the idea of dividing history into ancient, medieval, and “new period.”

The cultural phenomenon called the Renaissance began in Italy during the fourteenth century and spread throughout much of Europe by the end of the sixteenth century. It involved a flowering of art and scholarly and philosophical pursuits, often inspired by a renewed interest in the Classical cultures of ancient Greece and Rome. Some historians of the nineteenth century saw the Renaissance as a sharp break with the medieval “dark ages,” a sudden burst of intellectual light after the supposed gloom and stagnation of the Middle Ages.

Why did the number of indians living in mesoamerica decline from about 30 million in the fifteenth century to approximately 3 million by 1650?

Answers

Several Indian tribes who interacted with Europeans were wiped out by diseases brought by the Europeans. While Europe was in the early days of the Renaissance, there were empires in the Americas sustaining more than 60 million people.

The first European contact in 1492 brought diseases to the Americas which devastated the native population, and the resultant collapse of farming in the Americas was so significant that it may have even cooled the global climate. The time of the arrival of Europeans, the indigenous population was estimated to be just below 40 million people.

After the contact with European diseases it is said to be significantly reduced and estimates suggest that in 1650 this population could be around 8-9 million people.

What is Rural area?

A rural area, sometimes known as the countryside, is typically a region outside of towns and cities. Small villages and a low population density characterize typical rural areas.

Rural areas are often those that are agricultural or have forestry. For statistical and administrative purposes, the term "rural" might mean different things in different nations.

Rural economies differ significantly from urban economies in that they are more susceptible to boom-and-bust cycles and are dependent on land-based industries like agriculture, forestry, and resource extraction.

They are also more vulnerable to extreme weather events and natural disasters like droughts. Poorer infrastructure in rural areas and slower economic development affect rural services like healthcare and education.

Why is the marginal cost curve the same basic shape, no matter the product?

Answers

The marginal cost curve tends to exhibit the same basic shape across different products due to certain economic principles that are commonly observed in production processes.

While specific factors can lead to variations in the curve's exact position and slope, the underlying reasons for its shape are generally consistent. The marginal cost curve depicts the relationship between the quantity of output produced and the corresponding change in total cost incurred when producing an additional unit.

Here are some key reasons for the similarity in shape:

Law of Diminishing Marginal Returns: As production increases, the law of diminishing marginal returns comes into play. Initially, as more units are produced, the marginal cost tends to decrease due to economies of scale and improved efficiency. However, at a certain point, the marginal cost starts to increase as diminishing returns set in.

Spreading Fixed Costs: Fixed costs, such as rent, machinery, and equipment, are incurred regardless of the level of production. These costs are spread over a larger quantity of output as production increases, leading to a decrease in marginal cost.

Increasing Variable Costs: Variable costs, such as labor and raw materials, typically increase as production expands. These costs contribute to the upward slope of the marginal cost curve as more units are produced.

Technological Constraints: Technological limitations or production processes can also influence the shape of the marginal cost curve. For example, certain industries may face bottlenecks or limitations that cause marginal costs to rise more sharply at specific production levels.

Answers

A true statement about Continental, the German company formed in Paris in 1940 that invested in France's film industry is that It attempted to foster quality production with an annual prize of 100,000 francs for the best films of the year. The correct answer is option A.

Continental Films was a German company established in France in 1940 during World War II. The company, which was mainly responsible for importing German films into France and producing films in collaboration with French companies, was established in Paris by the German film industry.

While the company did invest in French film production, it did not sign up American stars and directors, nor did it aim to alleviate financial problems through government loans. As a result, it was instrumental in the development of France's film industry because of its high capital investment.  

Continental did, however, attempt to promote high-quality filmmaking in France by offering an annual prize of 100,000 francs for the best film of the year. This was part of the company's effort to gain credibility in the French film industry and compete with established French production companies.

Thus, Continental attempted to foster quality production with an annual prize of 100,000 francs for the best films of the year.

How did the United States use the changing relationship between China and the Soviet Union to its own advantage?

Answers

During the Cold War, the United States used the changing relationship between China and the Soviet Union to its own advantage by pursuing a policy of détente with China. As China and the Soviet Union became increasingly divided in the late 1960s and early 1970s, the United States saw an opportunity to exploit this rift and improve its own relations with China.

President Richard Nixon's historic visit to China in 1972 marked the beginning of a new era in U.S.-China relations, as the two countries began to establish diplomatic ties and cooperate on a range of issues, including trade and security.

By leveraging the split between China and the Soviet Union, the United States was able to strengthen its position in the Cold War and isolate the Soviet Union. This strategy ultimately helped to bring about the end of the Cold War and the collapse of the Soviet Union.
