Input: Article: It is a fundamental property of antennas that the electrical characteristics of an antenna described in the next section, such as gain, radiation pattern, impedance, bandwidth, resonant frequency and polarization, are the same whether the antenna is transmitting or receiving. For example, the "receiving pattern" (sensitivity as a function of direction) of an antenna when used for reception is identical to the radiation pattern of the antenna when it is driven and functions as a radiator. This is a consequence of the reciprocity theorem of electromagnetics. Therefore, in discussions of antenna properties no distinction is usually made between receiving and transmitting terminology, and the antenna can be viewed as either transmitting or receiving, whichever is more convenient.

Now answer this question: Are essential properties of an antenna changed based on what fungtion they are performing

Output: the same


Article: Tajikistan is officially a republic, and holds elections for the presidency and parliament, operating under a presidential system. It is, however, a dominant-party system, where the People's Democratic Party of Tajikistan routinely has a vast majority in Parliament. Emomalii Rahmon has held the office of President of Tajikistan continually since November 1994. The Prime Minister is Kokhir Rasulzoda, the First Deputy Prime Minister is Matlubkhon Davlatov and the two Deputy Prime Ministers are Murodali Alimardon and Ruqiya Qurbanova.

Question: Who are the Deputy Prime Ministers?
Ans: Murodali Alimardon and Ruqiya Qurbanova


Here is a question about this article: The People's Committees led to a high percentage of public involvement in decision making, within the limits permitted by the RCC, but exacerbated tribal divisions. They also served as a surveillance system, aiding the security services in locating individuals with views critical of the RCC, leading to the arrest of Ba'athists, Marxists and Islamists. Operating in a pyramid structure, the base form of these Committees were local working groups, who sent elected representatives to the district level, and from there to the national level, divided between the General People's Congress and the General People's Committee. Above these remained Gaddafi and the RCC, who remained responsible for all major decisions.
What is the answer to this question: What negative consequence did the People's Committees lead to?
****
So... tribal divisions

Plymouth is home to the Marine Biological Association of the United Kingdom (MBA) which conducts research in all areas of the marine sciences. The Plymouth Marine Laboratory is an offshoot of the MBA. Together with the National Marine Aquarium, the Sir Alister Hardy Foundation for Ocean Sciences, Plymouth University's Marine Institute and the Diving Diseases Research Centre, these marine-related organisations form the Plymouth Marine Sciences Partnership. The Plymouth Marine Laboratory, which focuses on global issues of climate change and sustainability. It monitors the effects of ocean acidity on corals and shellfish and reports the results to the UK government. It also cultivates algae that could be used to make biofuels or in the treatment of waste water by using technology such as photo-bioreactors. It works alongside the Boots Group to investigate the use of algae in skin care protects, taking advantage of the chemicals they contain that adapt to protect themselves from the sun.
What marine facility is attached to the University of Plymouth?
****
The answer: Marine Institute


Problem: Please answer a question about the following article about Buckingham Palace:
Directly underneath the State Apartments is a suite of slightly less grand rooms known as the semi-state apartments. Opening from the Marble Hall, these rooms are used for less formal entertaining, such as luncheon parties and private audiences. Some of the rooms are named and decorated for particular visitors, such as the 1844 Room, decorated in that year for the State visit of Tsar Nicholas I of Russia, and, on the other side of the Bow Room, the 1855 Room, in honour of the visit of Emperor Napoleon III of France. At the centre of this suite is the Bow Room, through which thousands of guests pass annually to the Queen's Garden Parties in the Gardens. The Queen and Prince Philip use a smaller suite of rooms in the north wing.
Where are the suites located that the Queen and Prince Phillip use?
A: the north wing


Question: Read this and answer the question

The rotating armature consists of one or more coils of wire wound around a laminated, magnetically "soft" ferromagnetic core. Current from the brushes flows through the commutator and one winding of the armature, making it a temporary magnet (an electromagnet). The magnetic field produced by the armature interacts with a stationary magnetic field produced by either PMs or another winding a field coil, as part of the motor frame. The force between the two magnetic fields tends to rotate the motor shaft. The commutator switches power to the coils as the rotor turns, keeping the magnetic poles of the rotor from ever fully aligning with the magnetic poles of the stator field, so that the rotor never stops (like a compass needle does), but rather keeps rotating as long as power is applied.

What element of the motor keeps the poles from alligning?
Answer:
commutator
