The precise strength of Earth's gravity varies with location. The agreed upon value for standard gravity is 9.80665 m/s 2 (32.1740 ft/s 2) by definition. [4] This quantity is denoted variously as gn, ge (though this sometimes means the normal gravity at the equator, 9.7803267715 m/s 2 (32.087686258 ft/s 2)), [5] g0, or simply g (which is also ...
The Pacific Plate moves northwestward relative to the North American Plate at about 2 inches (5.1 cm) to 2.5 inches (6.4 cm) per year, [29] meeting the continental landmass in the Gulf of Alaska. The Pacific Plate subducts under the Alaskan landmass, compressing the continental rocks and giving rise to a series of mountain ranges.
The CM-21 has floating capability, meaning it is able to cross water that is up to 1.5 metres (4.9 feet) deep without preparation. There are two water pumps that are switched on to lower the front flap. It is propelled by its tracks while in water. Just like the M113, the CM-21 can also have external fuel tanks mounted on the rear.
Standard gravity. The standard acceleration of gravity or standard acceleration of free fall, often called simply standard gravity and denoted by ɡ0 or ɡn, is the nominal gravitational acceleration of an object in a vacuum near the surface of the Earth. It is a constant defined by standard as 9.806 65 m/s 2 (about 32.174 05 ft/s 2).
A standard ring is between 16 and 24 feet (4.9 and 7.3 m) to a side between the ropes with another 2 feet (0.61 m) outside. The platform of the ring is generally 3 to 4 feet (0.91 to 1.22 m) from the ground and is covered by about 1 inch (25 mm) of padding topped by stretched canvas. The ropes are approximately 1 inch (25 mm) in diameter and at ...
The eighth generation of the Ford F-Series is a line of pickup trucks and light- to medium-duty commercial trucks produced by Ford from 1987 to 1991. While the previous generation cab and chassis were carried over with minor changes to the vent windows, interior trim mounting locations, and floor pan shape on the transmission hump, the 1987 model was more streamlined, and maintenance items ...
The Richter scale [1] (/ ˈ r ɪ k t ər /), also called the Richter magnitude scale, Richter's magnitude scale, and the Gutenberg–Richter scale, [2] is a measure of the strength of earthquakes, developed by Charles Richter in collaboration with Beno Gutenberg, and presented in Richter's landmark 1935 paper, where he called it the "magnitude scale".

Finger-jointed lumber – solid dimensional lumber lengths typically are limited to lengths of 22 to 24 feet (6.7–7.3 m), but can be made longer by the technique of "finger-jointing" by using small solid pieces, usually 18 to 24 inches (460–610 mm) long, and joining them together using finger joints and glue to produce lengths that can be ...
