Mass near the M87* black hole is converted into a very energetic astrophysical jet, stretching five thousand light years. In physics, mass–energy equivalence is the relationship between mass and energy in a system's rest frame, where the two quantities differ only by a multiplicative constant and the units of measurement.
ATSF 3000 class 2-10-10-2. The forward section of the boiler is a primitive superheater and feedwater heater.

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).
Ions of hydrogen and helium emit photons, which travel only a brief distance before being reabsorbed by other ions. [74] The density drops a hundredfold (from 20 000 kg/m 3 to 200 kg/m 3 ) between 0.25 solar radii and 0.7 radii, the top of the radiative zone.

Seals range in size from the 1 m (3 ft 3 in) and 45 kg (100 lb) Baikal seal to the 5 m (16 ft) and 3,200 kg (7,100 lb) southern elephant seal. Several species exhibit sexual dimorphism. They have streamlined bodies and four limbs that are modified into flippers. Though not as fast in the water as dolphins, seals are more flexible and agile ...
