In political geography, an enclave is a piece of land belonging to one country (or region etc.) that is totally surrounded by another country (or region). An exclave is a piece of land that is politically attached to a larger piece but not physically contiguous with it (connected to it) because they are completely separated by a surrounding foreign territory or territories.
Ohm's law states that the electric current through a conductor between two points is directly proportional to the voltage across the two points. Introducing the constant of proportionality, the resistance, [1] one arrives at the three mathematical equations used to describe this relationship: [2]
For power contracts made in the year 2014, the average price of wind power fell to 2.5¢/kWh. [42] The capacity factor is the ratio of power actually produced divided by the nameplate capacity of the turbines. The overall average capacity factor for wind generation in the US increased from 31.7% in 2008, to 32.3% in 2013.
The number π (/ p aɪ / ⓘ; spelled out as "pi") is a mathematical constant, approximately equal to 3.14159, that is the ratio of a circle's circumference to its diameter.It appears in many formulae across mathematics and physics, and some of these formulae are commonly used for defining π, to avoid relying on the definition of the length of a curve.
The 1918 household Gini coefficient (excluding capital gains) was 40.8. A brief but sharp depression in 1920-1921 reduced incomes. Income inequality rose from 1913 to peaks in 1926 (1928 Gini 48.9, 1936 Gini 45.5) and 1941 (Gini 43.1), after which war-time measures of the Roosevelt administration began to equalize the income distribution.

Google disclosed in September 2011 that it "continuously uses enough electricity to power 200,000 homes", almost 260 million watts or about a quarter of the output of a nuclear power plant. Total carbon emissions for 2010 were just under 1.5 million metric tons, mostly due to fossil fuels that provide electricity for the data centers.
People are classified as obese when their body mass index (BMI)—a person's weight divided by the square of the person's height—is over 30 kg/m 2; the range 25–30 kg/m 2 is defined as overweight. [1] Some East Asian countries use lower values to calculate obesity. [11]
Early smartphones were marketed primarily towards the enterprise market, attempting to bridge the functionality of standalone PDA devices with support for cellular telephony, but were limited by their bulky form, short battery life, slow analog cellular networks, and the immaturity of wireless data services.
