Question: Extract the answer to the question from the following context. Question: What is one assumes that there is no friction or other losses? Context: Energy transformations in the universe over time are characterized by various kinds of potential energy that has been available since the Big Bang later being "released" (transformed to more active types of energy such as kinetic or radiant energy) when a triggering mechanism is available. Familiar examples of such processes include nuclear decay, in which energy is released that was originally "stored" in heavy isotopes (such as uranium and thorium), by nucleosynthesis, a process ultimately using the gravitational potential energy released from the gravitational collapse of supernovae, to store energy in the creation of these heavy elements before they were incorporated into the solar system and the Earth. This energy is triggered and released in nuclear fission bombs or in civil nuclear power generation. Similarly, in the case of a chemical explosion, chemical potential energy is transformed to kinetic energy and thermal energy in a very short time. Yet another example is that of a pendulum. At its highest points the kinetic energy is zero and the gravitational potential energy is at maximum. At its lowest point the kinetic energy is at maximum and is equal to the decrease of potential energy. If one (unrealistically) assumes that there is no friction or other losses, the conversion of energy between these processes would be perfect, and the pendulum would continue swinging forever.
Answer: the conversion of energy between these processes would be perfect
[Q]: Extract the answer to the question from the following context. Question: What is the body part of an arrowhead called? Context: Iron is usually found as iron ore on Earth, except for one deposit of native iron in Greenland, which was used by the Inuit people. Native copper, however, was found worldwide, along with silver, gold and platinum, which were also used to make tools, jewelry, and other objects since Neolithic times. Copper was the hardest of these metals, and the most widely distributed. It became one of the most important metals to the ancients. Eventually, humans learned to smelt metals such as copper and tin from ore, and, around 2500 BC, began alloying the two metals to form bronze, which is much harder than its ingredients. Tin was rare, however, being found mostly in Great Britain. In the Middle East, people began alloying copper with zinc to form brass. Ancient civilizations took into account the mixture and the various properties it produced, such as hardness, toughness and melting point, under various conditions of temperature and work hardening, developing much of the information contained in modern alloy phase diagrams. Arrowheads from the Chinese Qin dynasty (around 200 BC) were often constructed with a hard bronze-head, but a softer bronze-tang, combining the alloys to prevent both dulling and breaking during use.

Context: In 1979, the U.S. placed Libya on its list of "State Sponsors of Terrorism", while at the end of the year a demonstration torched the U.S. embassy in Tripoli in solidarity with the perpetrators of the Iran hostage crisis. The following year, Libyan fighters began intercepting U.S. fighter jets flying over the Mediterranean, signalling the collapse of relations between the two countries. Libyan relations with Lebanon and Shi'ite communities across the world also deteriorated due to the August 1978 disappearance of imam Musa al-Sadr when visiting Libya; the Lebanese accused Gaddafi of having him killed or imprisoned, a charge he denied. Relations with Syria improved, as Gaddafi and Syrian President Hafez al-Assad shared an enmity with Israel and Egypt's Sadat. In 1980, they proposed a political union, with Libya paying off Syria's 1 billion debt to the Soviet Union; although pressures led Assad to pull out, they remained allies. Another key ally was Uganda, and in 1979, Gaddafi sent 2,500 troops into Uganda to defend the regime of President Idi Amin from Tanzanian invaders. The mission failed; 400 Libyans were killed and they were forced to retreat. Gaddafi later came to regret his alliance with Amin, openly criticising him.

output: Sadat

Context: The most extreme forms of Cubism were not those practiced by Picasso and Braque, who resisted total abstraction. Other Cubists, by contrast, especially Frantisek Kupka, and those considered Orphists by Apollinaire (Delaunay, Leger, Picabia and Duchamp), accepted abstraction by removing visible subject matter entirely. Kupka's two entries at the 1912 Salon d'Automne, Amorpha-Fugue a deux couleurs and Amorpha chromatique chaude, were highly abstract (or nonrepresentational) and metaphysical in orientation. Both Duchamp in 1912 and Picabia from 1912 to 1914 developed an expressive and allusive abstraction dedicated to complex emotional and sexual themes. Beginning in 1912 Delaunay painted a series of paintings entitled Simultaneous Windows, followed by a series entitled Formes Circulaires, in which he combined planar structures with bright prismatic hues; based on the optical characteristics of juxtaposed colors his departure from reality in the depiction of imagery was quasi-complete. In 191314 Leger produced a series entitled Contrasts of Forms, giving a similar stress to color, line and form. His Cubism, despite its abstract qualities, was associated with themes of mechanization and modern life. Apollinaire supported these early developments of abstract Cubism in Les Peintres cubistes (1913), writing of a new "pure" painting in which the subject was vacated. But in spite of his use of the term Orphism these works were so different that they defy attempts to place them in a single category.

Problem: Extract the answer to the question from the following context. Question: What is the third foreign influence on Egypt mentioned? Context: Egypt has one of the longest histories of any modern country, arising in the tenth millennium BC as one of the world's first nation states. Considered a cradle of civilisation, Ancient Egypt experienced some of the earliest developments of writing, agriculture, urbanisation, organised religion and central government. Iconic monuments such as the Giza Necropolis and its Great Sphinx, as well the ruins of Memphis, Thebes, Karnak, and the Valley of the Kings, reflect this legacy and remain a significant focus of archaeological study and popular interest worldwide. Egypt's rich cultural heritage is an integral part of its national identity, having endured, and at times assimilated, various foreign influences, including Greek, Persian, Roman, Arab, Ottoman, and European. Although Christianised in the first century of the Common Era, it was subsequently Islamised due to the Islamic conquests of the seventh century.

Context: On January 25, 1918, at the third meeting of the All-Russian Congress of Soviets, the unrecognized state was renamed the Soviet Russian Republic. On March 3, 1918, the Treaty of Brest-Litovsk was signed, giving away much of the land of the former Russian Empire to Germany, in exchange for peace in World War I. On July 10, 1918, the Russian Constitution of 1918 renamed the country the Russian Socialist Federative Soviet Republic. By 1918, during the Russian Civil War, several states within the former Russian Empire had seceded, reducing the size of the country even more.
