QUES: After about 1840, Georgian conventions were slowly abandoned as a number of revival styles, including Gothic Revival, that had originated in the Georgian period, developed and contested in Victorian architecture, and in the case of Gothic became better researched, and closer to their originals. Neoclassical architecture remained popular, and was the opponent of Gothic in the Battle of the Styles of the early Victorian period. In the United States the Federalist Style contained many elements of Georgian style, but incorporated revolutionary symbols.
What style from the United States used many elements of Georgian style but with revolutionary symbols?

ANS: Federalist Style

QUES: The inherent ambiguity of many control characters, combined with their historical usage, created problems when transferring "plain text" files between systems. The best example of this is the newline problem on various operating systems. Teletype machines required that a line of text be terminated with both "Carriage Return" (which moves the printhead to the beginning of the line) and "Line Feed" (which advances the paper one line without moving the printhead). The name "Carriage Return" comes from the fact that on a manual typewriter the carriage holding the paper moved while the position where the typebars struck the ribbon remained stationary. The entire carriage had to be pushed (returned) to the right in order to position the left margin of the paper for the next line.
What moves the printhead to the various operating systems?

ANS: unanswerable

QUES: Time is one of the seven fundamental physical quantities in both the International System of Units and International System of Quantities. Time is used to define other quantities—such as velocity—so defining time in terms of such quantities would result in circularity of definition. An operational definition of time, wherein one says that observing a certain number of repetitions of one or another standard cyclical event (such as the passage of a free-swinging pendulum) constitutes one standard unit such as the second, is highly useful in the conduct of both advanced experiments and everyday affairs of life. The operational definition leaves aside the question whether there is something called time, apart from the counting activity just mentioned, that flows and that can be measured. Investigations of a single continuum called spacetime bring questions about space into questions about time, questions that have their roots in the works of early students of natural philosophy.
Philosophy is one of how many fundamental physical quantities?

ANS: unanswerable

QUES: Large quantities of H
2 are needed in the petroleum and chemical industries. The largest application of H
2 is for the processing ("upgrading") of fossil fuels, and in the production of ammonia. The key consumers of H
2 in the petrochemical plant include hydrodealkylation, hydrodesulfurization, and hydrocracking. H
2 has several other important uses. H
2 is used as a hydrogenating agent, particularly in increasing the level of saturation of unsaturated fats and oils (found in items such as margarine), and in the production of methanol. It is similarly the source of hydrogen in the manufacture of hydrochloric acid. H
2 is also used as a reducing agent of metallic ores.
Where are large quantities of H2 needed?

ANS:
petroleum and chemical industries
