Question: Operating at normal power line frequencies, universal motors are often found in a range less than 1000 watts. Universal motors also formed the basis of the traditional railway traction motor in electric railways. In this application, the use of AC to power a motor originally designed to run on DC would lead to efficiency losses due to eddy current heating of their magnetic components, particularly the motor field pole-pieces that, for DC, would have used solid (un-laminated) iron and they are now rarely used.
Try to answer this question if possible: What were universal motor pole pieces constructed from?
Answer: solid (un-laminated) iron
Question: The synthesis of urea by Friedrich Wohler opened a new research field, organic chemistry, and by the end of the 19th century, scientists were able to synthesize hundreds of organic compounds. The later part of the 19th century saw the exploitation of the Earth's petrochemicals, after the exhaustion of the oil supply from whaling. By the 20th century, systematic production of refined materials provided a ready supply of products which provided not only energy, but also synthetic materials for clothing, medicine, and everyday disposable resources. Application of the techniques of organic chemistry to living organisms resulted in physiological chemistry, the precursor to biochemistry. The 20th century also saw the integration of physics and chemistry, with chemical properties explained as the result of the electronic structure of the atom. Linus Pauling's book on The Nature of the Chemical Bond used the principles of quantum mechanics to deduce bond angles in ever-more complicated molecules. Pauling's work culminated in the physical modelling of DNA, the secret of life (in the words of Francis Crick, 1953). In the same year, the MillerUrey experiment demonstrated in a simulation of primordial processes, that basic constituents of proteins, simple amino acids, could themselves be built up from simpler molecules.
Try to answer this question if possible: What scientific act is Friedrich Wohler known for?
Answer: The synthesis of urea
Question: Minority leaders may engage in numerous activities to publicize their party's priorities and to criticize the opposition's. For instance, to keep their party colleagues "on message," they insure that partisan colleagues are sent packets of suggested press releases or "talking points" for constituent meetings in their districts; they help to organize "town meetings" in Members' districts around the country to publicize the party's agenda or a specific priority, such as health care or education; they sponsor party "retreats" to discuss issues and assess the party's public image; they create "theme teams" to craft party messages that might be raised during the one-minute, morning hour, or special order period in the House; they conduct surveys of party colleagues to discern their policy preferences; they establish websites that highlight and distribute party images and issues to users; and they organize task forces or issue teams to formulate party programs and to develop strategies for communicating these programs to the public.
Try to answer this question if possible: How do minority leaders keep party priorities publicized?
Answer: "talking points" for constituent meetings in their districts; they help to organize "town meetings"
Question: The Free Officers' intention was not to install themselves in government, but to re-establish a parliamentary democracy. Nasser did not believe that a low-ranking officer like himself (a lieutenant colonel) would be accepted by the Egyptian people, and so selected General Naguib to be his "boss" and lead the coup in name. The revolution they had long sought was launched on 22 July and was declared a success the next day. The Free Officers seized control of all government buildings, radio stations, and police stations, as well as army headquarters in Cairo. While many of the rebel officers were leading their units, Nasser donned civilian clothing to avoid detection by royalists and moved around Cairo monitoring the situation. In a move to stave off foreign intervention two days before the revolution, Nasser had notified the American and British governments of his intentions, and both had agreed not to aid Farouk. Under pressure from the Americans, Nasser had agreed to exile the deposed king with an honorary ceremony.
Try to answer this question if possible: What type of government did the Free Officer's want to establish?
Answer:
parliamentary democracy
