Galena, also called lead glance, is the natural mineral form of lead(II) sulfide (PbS). It is the most important ore of lead and an important source of silver. [5]Galena is one of the most abundant and widely distributed sulfide minerals.
A silo was destroyed, a trailer was blown into outbuildings, and a brick home suffered roof damage. A 3,500 pounds (1,600 kg) horse trailer was rolled 220 yd (200 m), another trailer was rolled 50 to 75 yd (46 to 69 m), and two irrigation pivots were flipped over. A plank of wood was thrown through a car window and an outbuilding was moved off ...
Indian Ocean Dipole is an unusual pattern in the ocean-atmosphere system of the equatorial Indian Ocean that influences the monsoon and can offset the adverse impact of El Nino. It is typically characterized by cooler than normal eastern equatorial Indian Ocean and warmer than normal west and unusual equatorial easterly winds.
The longest known male tusk is 4.05 m (13.3 ft) long (measured along the outside curve) and weighs 115.5 kg (255 lb), with a historical report of a 4.30 m (14.1 ft) long tusk found in Siberia, while the heaviest tusk is 121 kg (267 lb), suggested to have been 125–130 kg (276–287 lb) when complete; [53] [54] 2.4–2.7 m (7 ft 10 in – 8 ft ...
The density at the surface is 65 kg/m 3 (4.1 lb/cu ft), 6.5% that of water [88] or 50 times as dense as Earth's atmosphere at 293 K (20 °C; 68 °F) at sea level. The CO 2 -rich atmosphere generates the strongest greenhouse effect in the Solar System, creating surface temperatures of at least 735 K (462 °C; 864 °F).
The average mass of an adult human is 59 kg (130 lb) for females and 77 kg (170 lb) for males. [161] [162] Like many other conditions, body weight and body type are influenced by both genetic susceptibility and environment and varies greatly among individuals. [163] [164] Humans have a far faster and more accurate throw than other animals. [165]
where ′ is the irradiance at the center of the pattern, represents the radial distance from the center of the pattern, and is the Gaussian RMS width (in one dimension). If we equate the peak amplitude of the Airy pattern and Gaussian profile, that is, I 0 ′ = I 0 , {\displaystyle I'_{0}=I_{0},} and find the value of ω 0 {\textstyle \omega ...
On the other hand, one scientific paper has claimed that the species can weigh up to 1,000 kg (2,200 lb) without providing more verifiable detail. [30] The leatherback turtle is scarcely larger than any other sea turtle upon hatching, as they average 61.3 mm (2.41 in) in carapace length and weigh around 46 g (1.6 oz) when freshly hatched.
