For instance, if a transmitter delivers 100 W into an antenna having an efficiency of 80%, then the antenna will radiate 80 W as radio waves and produce 20 W of heat. In order to radiate 100 W of power, one would need to use a transmitter capable of supplying 125 W to the antenna. Note that antenna efficiency is a separate issue from impedance matching, which may also reduce the amount of power radiated using a given transmitter. If an SWR meter reads 150 W of incident power and 50 W of reflected power, that means that 100 W have actually been absorbed by the antenna (ignoring transmission line losses). How much of that power has actually been radiated cannot be directly determined through electrical measurements at (or before) the antenna terminals, but would require (for instance) careful measurement of field strength. Fortunately the loss resistance of antenna conductors such as aluminum rods can be calculated and the efficiency of an antenna using such materials predicted.
What would need to be placed into the transmitter to create ten W oh warmth?
100 W

Input: Alexander Graham Bell
After setting up his workshop, Bell continued experiments based on Helmholtz's work with electricity and sound. He also modified a melodeon (a type of pump organ) so that it could transmit its music electrically over a distance. Once the family was settled in, both Bell and his father made plans to establish a teaching practice and in 1871, he accompanied his father to Montreal, where Melville was offered a position to teach his System of Visible Speech.

How did Bell's reworked melodeon send music?
Output: electrically

Input: Article: These and other differences reflect the differing design goals of the two buses: USB was designed for simplicity and low cost, while FireWire was designed for high performance, particularly in time-sensitive applications such as audio and video. Although similar in theoretical maximum transfer rate, FireWire 400 is faster than USB 2.0 Hi-Bandwidth in real-use, especially in high-bandwidth use such as external hard-drives. The newer FireWire 800 standard is twice as fast as FireWire 400 and faster than USB 2.0 Hi-Bandwidth both theoretically and practically. However, Firewire's speed advantages rely on low-level techniques such as direct memory access (DMA), which in turn have created opportunities for security exploits such as the DMA attack.

Now answer this question: USB was designed for what?

Output: simplicity and low cost

Article: Ann Arbor has a typically Midwestern humid continental climate (Koppen Dfa), which is influenced by the Great Lakes. There are four distinct seasons: winters are cold with moderate to heavy snowfall, while summers are very warm and humid, and spring and autumn are short but mild. The area experiences lake effect weather, primarily in the form of increased cloudiness during late fall and early winter. The monthly daily average temperature in July is 72.6 F (22.6 C), while the same figure for January is 24.5 F (4.2 C). Temperatures reach or exceed 90 F (32 C) on 10 days, and drop to or below 0 F (18 C) on 4.6 nights. Precipitation tends to be the heaviest during the summer months, but most frequent during winter. Snowfall, which normally occurs from November to April but occasionally starts in October, averages 58 inches (147 cm) per season. The lowest recorded temperature was 23 F (31 C) on 11 February 1885 and the highest recorded temperature was 105 F (41 C) on 24 July 1934.

Question: How many seasons are experienced in the city of Ann Arbor?
Ans: four

Here is a question about this article: Tito's visits to the United States avoided most of the Northeast due to large minorities of Yugoslav emigrants bitter about communism in Yugoslavia. Security for the state visits was usually high to keep him away from protesters, who would frequently burn the Yugoslav flag. During a visit to the United Nations in the late 1970s emigrants shouted "Tito murderer" outside his New York hotel, for which he protested to United States authorities.
What is the answer to this question: Which authorities fielded complaints from TIto about protesters?
****
So... United States authorities.

Article: Tuvalu participates in the operations of the Pacific Island Forum Fisheries Agency (FFA) and the Western and Central Pacific Fisheries Commission (WCPFC). The Tuvaluan government, the US government, and the governments of other Pacific islands, are parties to the South Pacific Tuna Treaty (SPTT), which entered into force in 1988. Tuvalu is also a member of the Nauru Agreement which addresses the management of tuna purse seine fishing in the tropical western Pacific. In May 2013 representatives from the United States and the Pacific Islands countries agreed to sign interim arrangement documents to extend the Multilateral Fisheries Treaty (which encompasses the South Pacific Tuna Treaty) to confirm access to the fisheries in the Western and Central Pacific for US tuna boats for 18 months. Tuvalu and the other members of the Pacific Island Forum Fisheries Agency (FFA) and the United States have settled a tuna fishing deal for 2015; a longer term deal will be negotiated. The treaty is an extension of the Nauru Agreement and provides for US flagged purse seine vessels to fish 8,300 days in the region in return for a payment of US$90 million made up by tuna fishing industry and US-Government contributions. In 2015 Tuvalu has refused to sell fishing days to certain nations and fleets that have blocked Tuvaluan initiatives to develop and sustain their own fishery.

Question: What did Tuvalu refuse to sell in 2015?
Ans:
fishing days
