The proportional dimensions of pre-decimal coins continued past Decimal Day, meaning that the 2p and 10p coins weighed twice the 1p and 5p respectively; this correlation was continued when the 5p (1990) and 10p (1992) coins were reduced in size, leading to the situation that full bags of 1p and 2p coins, and 5p and 10p coins, have the same ...
In this underwater lift, the chamber was 80 ft (24.4 m) long and 60 ft (18.3 m) deep and contained a completely enclosed wooden box big enough to take a barge. This box moved up and down in the 60 ft (18.3 m) deep pool of water. Apart from inevitable leakage, the water never left the chamber, and using the lock wasted no water. Instead, the ...

The three main reasons why global warming causes sea levels to rise are the expansion of oceans due to heating, water inflow from melting ice sheets and water inflow from glaciers. Other factors affecting sea level rise include changes in snow mass, and flow from terrestrial water storage, though the contribution from these is thought to be ...
The stream of water is about one inch in diameter, and falls from a hight of seven or eight feet. The head of the patient is retained in its place by means of a board clasping the neck; the effect of which is, that the water, striking upon the board, rebounds into the mouth and nostrils of the victim, almost producing strangulation.

The city limits also have expanded across the Cooper River, encompassing Daniel Island and the Cainhoy area.
Hydraulic fracturing [a] is a well stimulation technique involving the fracturing of formations in bedrock by a pressurized liquid. The process involves the high-pressure injection of "fracking fluid" (primarily water, containing sand or other proppants suspended with the aid of thickening agents) into a wellbore to create cracks in the deep rock formations through which natural gas, petroleum ...
On the other hand, the algorithm for square root extraction, of which the best known pencil-and-paper form is still the one developed by Hero of Alexandria, [19] is nowadays rarely taught, even in secondary school. Standard: Using a base of 2, the logarithm of 32 is 5, because 2 5 equals 32.
