Country code top-level domain. A country code top-level domain (ccTLD) is an Internet top-level domain generally used or reserved for a country, sovereign state, or dependent territory identified with a country code. All ASCII ccTLD identifiers are two letters long, and all two-letter top-level domains are ccTLDs.
A URL is a specific type of Uniform Resource Identifier (URI), [2][3] although many people use the two terms interchangeably. [4][a] URLs occur most commonly to reference web pages (HTTP / HTTPS) but are also used for file transfer (FTP), email (mailto), database access (JDBC), and many other applications.
The square kilometre (square kilometer in American spelling; symbol: km2) is a multiple of the square metre, the SI unit of area or surface area. 1 km 2 is equal to: 1,000,000 square metres (m 2) 100 hectares (ha) It is also approximately equal to: 0.3861 square miles [2] 247.1 acres [3] Conversely: 1 m 2 = 0.000001 (10 −6) km 2.
The centimetre (SI symbol: cm) is a unit of length in the metric system equal to 10−2 metres ( 1 100 m = 0.01 m). To help compare different orders of magnitude, this section lists lengths between 10 −2 m and 10 −1 m (1 cm and 1 dm). 1 cm – 10 millimetres. 1 cm – 0.39 inches. 1 cm – edge of a square of area 1 cm 2.
A URN may be used to talk about a resource without implying its location or how to access it. For example, in the International Standard Book Number (ISBN) system, ISBN 0-486-27557-4 identifies a specific edition of the William Shakespeare play Romeo and Juliet. The URN for that edition would be urn:isbn:0-486-27557-4. However, it gives no ...
For example, 5 km is treated as 5000 m, which allows all quantities based on the same unit to be factored together even if they have different prefixes. A prefix symbol attached to a unit symbol is included when the unit is raised to a power. For example, 1 km 2 denotes 1 km × 1 km = 10 6 m 2, not 10 3 m 2.
1/52! chance of a specific shuffle Mathematics: The chances of shuffling a standard 52-card deck in any specific order is around 1.24 × 10 −68 (or exactly 1 ⁄ 52!) [4] Computing: The number 1.4 × 10 −45 is approximately equal to the smallest positive non-zero value that can be represented by a single-precision IEEE floating-point value.
1.7×10 −21 J. 1 kJ/mol, converted to energy per molecule [9] 2.1×10 −21 J. Thermal energy in each degree of freedom of a molecule at 25 °C (kT /2) (0.01 eV) [10] 2.856×10 −21 J. By Landauer's principle, the minimum amount of energy required at 25 °C to change one bit of information. 3–7×10 −21 J.
