Answer:

Explanation:

Economists use the term demand to refer to the amount of some good or service consumers are willing and able to purchase at each price. Demand is based on needs and wants—a consumer may be able to differentiate between a need and a want, but from an economist’s perspective they are the same thing. Demand is also based on ability to pay. If you cannot pay, you have no effective demand.

What a buyer pays for a unit of the specific good or service is called price. The total number of units purchased at that price is called the quantity demanded. An increase in the price of a good or service almost always decreases the quantity demanded of that good or service. Conversely, a decrease in price will increase the quantity demanded.

When the price of a gallon of gasoline goes up, for example, people look for ways to reduce their consumption by combining several errands, commuting by carpool or mass transit, or taking weekend or vacation trips closer to home. Economists call this inverse relationship between price and quantity demanded the law of demand. The law of demand assumes that all other variables that affect demand are held constant.

Demand schedule and demand curve

A demand schedule is a table that shows the quantity demanded at each price.

A demand curve is a graph that shows the quantity demanded at each price. Sometimes the demand curve is also called a demand schedule because it is a graphical representation of the demand scheduls.

Here's an example of a demand schedule from the market for gasoline.

Price (per gallon) Quantity demanded (millions of gallons)

\$1.00$1.00dollar sign, 1, point, 00 800800800

\$1.20$1.20dollar sign, 1, point, 20 700700700

\$1.40$1.40dollar sign, 1, point, 40 600600600

\$1.60$1.60dollar sign, 1, point, 60 550550550

\$1.80$1.80dollar sign, 1, point, 80 500500500

\$2.00$2.00dollar sign, 2, point, 00 460460460

\$2.20$2.20dollar sign, 2, point, 20 420420420

Price, in this case, is measured in dollars per gallon of gasoline. The quantity demanded is measured in millions of gallons over some time period—for example, per day or per year—and over some geographic area—like a state or a country.

How did inventors in the field of communication improve on each other's earlier designs?

serious [3.7K]

Experiments on communication with electricity, initially unsuccessful, started in about 1726. Scientists including Laplace, Ampère, and Gauss were involved.

An early experiment in electrical telegraphy was an 'electrochemical' telegraph created by the German physician, anatomist and inventor Samuel Thomas von Sömmerring in 1809, based on an earlier, less robust design of 1804 by Spanish polymath and scientist Francisco Salva Campillo.[8]Both their designs employed multiple wires (up to 35) in order to visually represent almost all Latin letters and numerals. Thus, messages could be conveyed electrically up to a few kilometers (in von Sömmerring's design), with each of the telegraph receiver's wires immersed in a separate glass tube of acid. An electric current was sequentially applied by the sender through the various wires representing each digit of a message; at the recipient's end the currents electrolysed the acid in the tubes in sequence, releasing streams of hydrogen bubbles next to each associated letter or numeral. The telegraph receiver's operator would visually observe the bubbles and could then record the transmitted message, albeit at a very low baud rate.[8] The principal disadvantage to the system was its prohibitive cost, due to having to manufacture and string-up the multiple wire circuits it employed, as opposed to the single wire (with ground return) used by later telegraphs.

The first working telegraph was built by Francis Ronalds in 1816 and used static electricity.[9]

Charles Wheatstone and William Fothergill Cooke patented a five-needle, six-wire system, which entered commercial use in 1838.[10] It used the deflection of needles to represent messages and started operating over twenty-one kilometres (thirteen miles) of the Great Western Railway on 9 April 1839. Both Wheatstone and Cooke viewed their device as "an improvement to the [existing] electromagnetic telegraph" not as a new device.

On the other side of the Atlantic Ocean, Samuel Morse developed a version of the electrical telegraph which he demonstrated on 2 September 1837. Alfred Vail saw this demonstration and joined Morse to develop the register—a telegraph terminal that integrated a logging device for recording messages to paper tape. This was demonstrated successfully over three miles (five kilometres) on 6 January 1838 and eventually over forty miles (sixty-four kilometres) between Washington, D.C. and Baltimore on 24 May 1844. The patented invention proved lucrative and by 1851 telegraph lines in the United States spanned over 20,000 miles (32,000 kilometres).[11] Morse's most important technical contribution to this telegraph was the simple and highly efficient Morse Code, co-developed with Vail, which was an important advance over Wheatstone's more complicated and expensive system, and required just two wires. The communications efficiency of the Morse Code preceded that of the Huffman code in digital communications by over 100 years, but Morse and Vail developed the code purely empirically, with shorter codes for more frequent letters.

The submarine cable across the English Channel, wire coated in gutta percha, was laid in 1851.[12] Transatlantic cables installed in 1857 and 1858 only operated for a few days or weeks (carried messages of greeting back and forth between James Buchanan and Queen Victoria) before they failed.[13] The project to lay a replacement line was delayed for five years by the American Civil War. The first successful transatlantic telegraph cable was completed on 27 July 1866, allowing transatlantic telecommunication for the first time.

What was one of the responsibilities of the Farm Security Administration?

Oksana_A [137]

Answer:

The correct answer is A. One of the responsibilities of the Farm Security Administration was the documentation project that resulted in photographs of towns during the Depression.

Explanation:

The Farm Security Administration (FSA) was a company that was created in the US in 1935 under the New Deal. Its purpose was to help America's rural poor population. The FSA supported the acquisition of marginal lands, field work with modern machines and collectivization.

In 1935, FSA launched a photographic campaign in which a number of photographers joined the sociological and documentary program. Its task was to compile documentation of social problems in the southern states of the United States. Its main characteristics were the emphasis on realism, the effort without embellishment to capture things as they were, the coexistence of poverty and suffering, a clear moral attitude, and finally the very awareness of the specificity of this medium. Photographers employed by the company have created approximately 1,600 color photographs that capture life in the United States, including Puerto Rico and the Virgin Islands.
