Neutron stars have overall densities of 3.7 × 10 17 to 5.9 × 10 17 kg/m 3 (2.6 × 10 14 to 4.1 × 10 14 times the density of the Sun), [a] which is comparable to the approximate density of an atomic nucleus of 3 × 10 17 kg/m 3. [24] The density increases with depth, varying from about 1 × 10 9 kg/m 3 at the crust to an estimated 6 × 10 17 ...
Fusing four free protons (hydrogen nuclei) into a single alpha particle (helium nucleus) releases around 0.7% of the fused mass as energy, [68] so the Sun releases energy at the mass–energy conversion rate of 4.26 billion kg/s (which requires 600 billion kg of hydrogen [69]), for 384.6 yottawatts (3.846 × 10 26 W), [5] or 9.192 × 10 10 ...
ATSF 3000 class 2-10-10-2. The forward section of the boiler is a primitive superheater and feedwater heater. In 1911 and 1912, the Atchison, Topeka and Santa Fe Railway modified ten 2-10-2 Baldwin -built locomotives into a new 2-10-10-2 configuration dubbed the 3000 class.

They produced a mean of 1.4 litters per year, but a maximum of three litters in a year. Of 169 kittens, 127 died before they were six months old due to a trauma caused in most cases by dog attacks and road accidents. [160] The first litter is usually smaller than subsequent litters. Kittens are weaned between six and seven weeks of age.

Paraglider wings typically have an area of 20–35 square metres (220–380 sq ft) with a span of 8–12 metres (26–39 ft) and weigh 3–7 kilograms (6.6–15.4 lb). Combined weight of wing, harness, reserve, instruments, helmet, etc. is around 12–22 kilograms (26–49 lb). Ultralight Hike & Fly kits can be lighter than 5 kilograms (11 lb).
Ammonia is an inorganic chemical compound of nitrogen and hydrogen with the formula N H 3.A stable binary hydride and the simplest pnictogen hydride, ammonia is a colourless gas with a distinctive pungent smell.
