Student A:Emilie du Chatelet (1706 -- 1749) proposed and tested the hypothesis of the conservation of total energy, as distinct from momentum. Inspired by the theories of Gottfried Leibniz, she repeated and publicized an experiment originally devised by Willem' s Gravesande in 1722 in which balls were dropped from different heights into a sheet of soft clay. Each ball's kinetic energy-as indicated by the quantity of material displaced-was shown to be proportional to the square of the velocity. The deformation of the clay was found to be directly proportional to the height the balls were dropped from, equal to the initial potential energy. Earlier workers, including Newton and Voltaire, had all believed that "energy" (so far as they understood the concept at all) was not distinct from momentum and therefore proportional to velocity. According to this understanding, the deformation of the clay should have been proportional to the square root of the height from which the balls were dropped from. In classical physics the correct formula is E k = 1 2 m v 2 (\ displaystyle E_ ( k) = (\ frac ( 1) (2) ) mv ^ (2) ), where E k (\ displaystyle E_ ( k) ) is the kinetic energy of an object, m (\ displaystyle m) its mass and v (\ displaystyle v) its speed. On this basis, Chatelet proposed that energy must always have the same dimensions in any form, which is necessary to be able to relate it in different forms (kinetic, potential, heat ...).

Problem:Texas v. Johnson, 491 U.S. 397 (1989), was a decision by the Supreme Court of the United States that invalidated prohibitions on desecrating the American flag enforced in 48 of the 50 states. Justice William Brennan wrote for a five-justice majority in holding that the defendant Gregory Lee Johnson's act of flag burning was protected speech under the First Amendment to the United States Constitution. Johnson was represented by attorneys David D. Cole and William Kunstler.

the defendant Gregory Lee Johnson 's act of flag burning was protected speech under the First Amendment to the United States Constitution.

Student A:Passage: The nucleolus (/ nj u klils,-kliols /, plural nucleoli /-la /) is the largest structure in the nucleus of eukaryotic cells. It is best known as the site of ribosome biogenesis. Nucleoli also participate in the formation of signal recognition particles and play a role in the cell's response to stress. Nucleoli are made of proteins, DNA and RNA and form around specific chromosomal regions called nucleolar organizing regions. Malfunction of nucleoli can be the cause of several human conditions called "nucleolopathies" and the nucleolus is being investigated as a target for cancer chemotherapy.

Question: Based on this passage, the nucleoli found within the nucleus are the sites of ____ synthesis.?
Student B:OK... To answer the above question, the relevant sentence is: It is best known as the site of ribosome biogenesis.
ribosome.

Problem:Context: Throughout The Faerie Queene, Spenser creates "a network of allusions to events, issues, and particular persons in England and Ireland" including Mary, Queen of Scots, the Spanish Armada, the English Reformation, and even the Queen herself. It is also known that James VI of Scotland read the poem, and was very insulted by Duessa -- a very negative depiction of his mother, Mary, Queen of Scots. The Faerie Queene was then banned in Scotland. This led to a significant decrease in Elizabeth's support for the poem. Within the text, both the Faerie Queene and Belphoebe serve as two of the many personifications of Queen Elizabeth, some of which are "far from complimentary".

Question: which character of spenser represents queen mary of scots?
Solution:OK... The relevant sentence in the passage is: It is also known that James VI of Scotland read the poem, and was very insulted by Duessa -- a very negative depiction of his mother, Mary, Queen of Scots.
Duessa.

Student A:A lower pair is an ideal joint that constrains contact between a surface in the moving body to a corresponding surface in the fixed body. A lower pair is one in which there occurs a surface or area contact between two members, e.g. nut and screw, universal joint used to connect two propeller shafts. Cases of lower joints:

Answer this question: universal joint is an example of which pair?
Student B:OK... The relevant information is: A lower pair is one in which there occurs a surface or area contact between two members, e.g. nut and screw, universal joint used to connect two propeller shafts.
A lower pair.
