1 giorno fa · The decimal representation for one thousand is. 1000 —a one followed by three zeros, in the general notation; 1 × 103 —in engineering notation, which for this number coincides with: 1 × 103 exactly—in scientific normalized exponential notation; 1 E+3 exactly—in scientific E notation.
3 giorni fa · As of 2020, the most expensive non- synthetic element by both mass and volume is rhodium. It is followed by caesium, iridium and palladium by mass and iridium, gold and platinum by volume. Carbon in the form of diamond can be more expensive than rhodium. Per-kilogram prices of some synthetic radioisotopes range to trillions of dollars.
3 giorni fa · Moments of inertia may be expressed in units of kilogram metre squared (kg·m 2) in SI units and pound-foot-second squared (lbf·ft·s 2) in imperial or US units. The moment of inertia plays the role in rotational kinetics that mass (inertia) plays in linear kinetics—both characterize the resistance of a body to changes in its motion.
1 giorno fa · Energy released by explosion of 1 kilogram of TNT: 8.4×10 6 J: Recommended food energy intake per day for a moderately active woman (2000 food calories) 9.1×10 6 J Kinetic energy of a regulation baseball thrown at Earth's escape velocity (First cosmic velocity ≈ 11.186 km/s = 25,020 mph = 40,270 km/h). 10 7 1×10 7 J
3 giorni fa · Just like specific energy, specific power is measured either gravimetrically in kilowatts per kilogram (kW/kg, specific power) or volumetrically in kilowatts per litre (kW/L, power density). Supercapacitor specific power is typically 10 to 100 times greater than for batteries and can reach values up to 15 kW/kg.
19 ore fa · Saffron "threads", plucked from crocus flowers and dried. Saffron ( / ˈsæfrən, - rɒn /) [1] is a spice derived from the flower of Crocus sativus, commonly known as the "saffron crocus". The vivid crimson stigma and styles, called threads, are collected and dried for use mainly as a seasoning and colouring agent in food.
2 giorni fa · On 29 October 2012, an unexploded 250-kilogram (550 lb) US bomb with a functioning detonator was discovered near a runway at Sendai Airport during reconstruction following the 2011 Tōhoku earthquake and tsunami, resulting in the airport being closed and all flights cancelled.
