If the n + 1 digit is greater than 5 or is 5 followed by other non-zero digits, add 1 to the n digit. For example, if we want to round 1.2459 to 3 significant figures, then this step results in 1.25. For example, if we want to round 1.2459 to 3 significant figures, then this step results in 1.25.
If its temperature is allowed to change by 1 °C, its mass changes by 1.5 picograms (1 pg = 1 × 10 −12 g). [note 5] A spinning ball has greater mass than when it is not spinning. Its increase of mass is exactly the equivalent of the mass of energy of rotation, which is itself the sum of the kinetic energies of all the moving parts of the ball.
Most fluxes quoted in high-level discussions of climate are global values, which means they are the total flow of energy over the entire globe, divided by the surface area of the Earth, 5.1 × 10 14 m 2 (5.1 × 10 8 km 2; 2.0 × 10 8 sq mi).
In the widely accepted ΛCDM cosmological model, dark matter accounts for about 25.8% ± 1.1% of the mass and energy in the universe while about 69.2% ± 1.2% is dark energy, a mysterious form of energy responsible for the acceleration of the expansion of the universe. [17] Ordinary ('baryonic') matter therefore composes only 4.84% ± 0.1% of ...
The CGS unit is the poise (P, or g·cm −1 ·s −1 = 0.1 Pa·s), [28] named after Jean Léonard Marie Poiseuille. It is commonly expressed, particularly in ASTM standards, as centipoise (cP). The centipoise is convenient because the viscosity of water at 20 °C is about 1 cP, and one centipoise is equal to the SI millipascal second (mPa·s).
The overall impact of hyperinflation was that 1 novi dinar was equal to 1 × 10 27 – 1.3 × 10 27 pre-1990 dinars. Yugoslavia's rate of inflation hit 5 × 10 15 % cumulative inflation over the time period 1 October 1993 and 24 January 1994. SFR Yugoslavia: Start and end date: September 1989 – December 1989
The son of Aglaos, Eratosthenes was born in 276 BC in Cyrene.Now part of modern-day Libya, Cyrene had been founded by Greeks centuries earlier and became the capital of Pentapolis (North Africa), a country of five cities: Cyrene, Arsinoe, Berenice, Ptolemias, and Apollonia.
As another example, in a population where the lowest 50% of individuals have no income, and the other 50% have equal income, the Gini coefficient is 0.5; whereas for another population where the lowest 75% of people have 25% of income and the top 25% have 75% of the income, the Gini index is also 0.5.
