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.

Aburish asserts that Nasser was not distressed by his frequent relocations, which broadened his horizons and showed him Egyptian society's class divisions. His own social status was well below the wealthy Egyptian elite, and his discontent with those born into wealth and power grew throughout his lifetime. Nasser spent most of his spare time reading, particularly in 1933 when he lived near the National Library of Egypt. He read the Qur'an, the sayings of Muhammad, the lives of the Sahaba (Muhammad's companions), and the biographies of nationalist leaders Napoleon, Ataturk, Otto von Bismarck, and Garibaldi and the autobiography of Winston Churchill.
What was Nasser's position in Egypt's society?
A: well below the wealthy Egyptian elite

The decline of Constantinople – a main trading partner of Kievan Rus' – played a significant role in the decline of the Kievan Rus'. The trade route from the Varangians to the Greeks, along which the goods were moving from the Black Sea (mainly Byzantine) through eastern Europe to the Baltic, was a cornerstone of Kiev wealth and prosperity. Kiev was the main power and initiator in this relationship, once the Byzantine Empire fell into turmoil and the supplies became erratic, profits dried out, and Kiev lost its appeal.[citation needed]
What terriroty did the trade from the Varangians to the Greeks route mainly go through?
A: Byzantine

Sony confirmed that there was an error and stated that they were narrowing down the issue and were continuing to work to restore service. By March 2 (UTC), 2010, owners of original PS3 models could connect to PSN successfully and the clock no longer showed December 31, 1999. Sony stated that the affected models incorrectly identified 2010 as a leap year, because of a bug in the BCD method of storing the date. However, for some users, the hardware's operating system clock (mainly updated from the internet and not associated with the internal clock) needed to be updated manually or by re-syncing it via the internet.
By what date did Sony correct the issue with the system disk?
A:
unanswerable
