10 godz. temu · Q1.1 The person first moves 70m east and then 30m west. The total distance covered by the person is the sum of these two distances, which is 70m + 30m = 100m. However, displacement is the shortest distance from the initial to the final position of the person. Since the person moved 70m east and then 30m west, the displacement is 70m - 30m = 40m.
1 dzień temu · Enrico Fermi (1901–1954) The Fermi paradox is a conflict between the argument that scale and probability seem to favor intelligent life being common in the universe, and the total lack of evidence of intelligent life having ever arisen anywhere other than on Earth. The first aspect of the Fermi paradox is a function of the scale or the large ...
10 godz. temu · The distance the light from the edge of the observable universe has traveled is very close to the age of the universe times the speed of light, 13.8 billion light-years (4.2 × 10 ^ 9 pc), but this does not represent the distance at any given time because the edge of the observable universe and the Earth have since moved further apart.
10 godz. temu · The Sun is the star at the center of the Solar System.It is a massive, nearly perfect sphere of hot plasma, heated to incandescence by nuclear fusion reactions in its core, radiating the energy from its surface mainly as visible light and infrared radiation with 10% at ultraviolet energies. It is by far the most important source of energy for life on Earth. ...
10 godz. temu · A metal (from Ancient Greek μέταλλον (métallon) 'mine, quarry, metal') is a material that when polished, or fractured, shows a lustrous appearance, and conducts electricity and heat relatively well. These properties are all associated with having electrons available at the Fermi level, as against nonmetallic materials which do not.: Chpt 8 & 19 : Chpt 7 & 8 Metals are typically ...
10 godz. temu · The Moon is Earth's only natural satellite.It orbits at an average distance of 384,400 km (238,900 mi), about 30 times the diameter of Earth. Tidal forces between Earth and the Moon have over time synchronized the Moon's orbital period (lunar month) with its rotation period at 29.5 Earth days, causing the same side of the Moon to always face Earth. . The Moon's gravitational pull – and to a ...
10 godz. temu · Diabetes mellitus cases due to a known defect are classified separately. Type 2 diabetes is the most common type of diabetes mellitus accounting for 95% of diabetes. Many people with type 2 diabetes have evidence of prediabetes (impaired fasting glucose and/or impaired glucose tolerance) before meeting the criteria for type 2 diabetes.
