Introduction

The term energy has various meanings and definitions related to the idea of a capacity to work, transforming or put in motion. In physics, 'energy' is defined as the capacity to perform work. Technology and economy, "energy" refers to a natural resource (including its associated technology) to remove it, transform it, and then give an economic or industrial use (Adams, Adams, 2001).

In theoretical physics, energy is defined as the size, which is due to the time-invariance of the laws of nature will receive. Many introductory texts define energy in the anschaulicherer, however not more general form as the ability to perform mechanical work, to make heat or emit light. The maximum work that can do it is called energy of technical thermodynamics. Energy is needed to accelerate a body or contrary to a power to move him to a substance to heat up, to compress a gas to electric current flowing to or radiate electromagnetic waves . Plants, animals and humans need energy to live. You need energy for the operation of computer systems, telecommunications, and for any economic production (Adams, Adams, 2001).

Energy can appear in different forms of energy. These include, for example, potential energy, kinetic energy, chemical energy or thermal energy. Energy can be cast to different forms of energy. This can the total energy within a closed System due to the energy conservation cannot be increased or reduced. Continue to the second law of thermodynamics that fundamental boundaries, in particular are convertibility is thermal energy limited in other forms of energy converts and between systems transferable (Adams, Adams, 2001). According to the Einstein theory of relativity must be associated with an energy also a resting mass m of the amount of E = mc2.

Population of the nation

According to the Constitution of the United States, United States Census is conducted every 10 years, since 1790. The previous census was conducted in 2000. Participation in the census is required in strict accordance with the 13th United States Code, section. On the 25th of January 2010, the Director of United States Census Bureau, Robert Groves personally began a census of 2010, the first of which was a veteran of the of the second world war Clifton Jackson. Questionnaires were delivered on 15 March 2010; their number amounted to about 134 million. In December, 2010, the President was provided with information on the census, and in March 2011 — about its completion (Adams, Adams, 2001).

The Census Bureau said on Tuesday, December 21st, 2010 that the population of the United States of America had increased by 9.7 per cent over the past decade, a slower growth in the United States since the 1930s. The total number of inhabitants rose to 308.7 million until April 2010, an increase of 9.7 per cent compared to a decade ago, the second lowest rate during the last century, said Robert groves, Director of the Bureau of census, announcing the results at a press ...
