Student A:H-alpha (H) is a specific deep-red visible spectral line in the Balmer series with a wavelength of 656.28 nm in air; it occurs when a hydrogen electron falls from its third to second lowest energy level. H-alpha light is important to astronomers as it is emitted by many emission nebulae and can be used to observe features in the Sun's atmosphere, including solar prominences and the chromosphere.

Based on this passage, when is h alpha line in the emission spectrum of hydrogen atom obtained?
Student B:OK... The relevant sentence in the passage is: H-alpha (H) is a specific deep-red visible spectral line in the Balmer series with a wavelength of 656.28 nm in air; it occurs when a hydrogen electron falls from its third to second lowest energy level.
when a hydrogen electron falls from its third to second lowest energy level.

Problem:The Tokugawa shogunate, also known as the Tokugawa bakufu ( ) and the Edo bakufu ( ), was the last feudal Japanese military government, which existed between 1600 and 1868. The head of government was the shogun, and each was a member of the Tokugawa clan. The Tokugawa shogunate ruled from Edo Castle and the years of the shogunate became known as the Edo period. This time is also called the Tokugawa period or pre-modern (Kinsei ( ) ).

Answer this question based on the passage: what was the significance of the tokugawa shogunate?
Solution:OK... To answer the above question, the relevant sentence is: The Tokugawa shogunate, also known as the Tokugawa bakufu ( ) and the Edo bakufu ( ), was the last feudal Japanese military government, which existed between 1600 and 1868.
the last feudal Japanese military government.

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 ...).

Who made the law of conservation of energy?
Student B:OK... To answer the question, consider the following: Emilie du Chatelet (1706 -- 1749) proposed and tested the hypothesis of the conservation of total energy, as distinct from momentum.
Emilie du Chatelet.

Student A:Passage: Since 1917, the British Army's salute has been given with the right hand palm facing forwards with the fingers almost touching the cap or beret. Before 1917, the salute was given with whichever hand was furthest from the person being saluted, whether that was the right or the left. The salute is given to acknowledge the Queen's commission. A salute may not be given unless a soldier is wearing his regimental headdress, for example a Beret, Caubeen, Tam o' Shanter, Glengarry, field service cap or peaked cap. This does not apply to members of The Blues and Royals (RHG / 1stD) The Household Cavalry who, after The Battle of Warburg were allowed to salute without headdress. If a soldier or officer is not wearing headdress then he or she must come to attention instead of giving / returning the salute. The subordinate salutes first and maintains the salute until the superior has responded in kind.

Question: Based on this passage, who do you salute in the british army?
Student B:
OK... To answer the above question, the relevant sentence is: The subordinate salutes first and maintains the salute until the superior has responded in kind.
the superior.
