China, [h] officially the People's Republic of China ( PRC ), [i] is a country in East Asia. With a population exceeding 1.4 billion, it is the world's second-most populous country after India. China spans the equivalent of five time zones and borders fourteen countries by land.
the free encyclopedia that anyone can edit. Bill Newton (8 June 1919 – 29 March 1943) was an Australian recipient of the Victoria Cross, honoured for his actions as a bomber pilot in Papua New Guinea during March 1943. Raised in Melbourne, he joined the Citizen Military Forces in 1938 and enlisted in the Royal Australian Air Force (RAAF) in ...
Bluetooth is a short-range wireless technology standard that is used for exchanging data between fixed and mobile devices over short distances and building personal area networks (PANs). In the most widely used mode, transmission power is limited to 2.5 milliwatts, giving it a very short range of up to 10 metres (33 ft).
Overview. The nine world zones are generally organized geographically, with exceptions for political and historical alignment. Zone 1 uses an integrated numbering plan; four digits (1xxx) determine the area served in Canada, the United States and its territories, and much of the Caribbean.

In terms of SI base units and in terms of SI derived units with special names, the joule is defined as One joule is also equivalent to any of the following: 1. The work required to move an electric charge of one coulomb through an electrical potential differenceof one volt, or one coulomb-volt (C⋅V). This relationship can be used to define the volt...
The cgs system had been declared official in 1881, at the first International Electrical Congress.The erg was adopted as its unit of energy in 1882. Wilhelm Siemens, in his inauguration speech as chairman of the British Association for the Advancement of Science (23 August 1882) first proposed the Joule as unit of heat, to be derived from the elect...
One joule represents (approximately): 1. The amount of electricity required to run a 1 W device for 1 s. 2. The energy required to accelerate a 1 kg mass at 1 m/s2 through a distance of 1 m. 3. The kinetic energy of a 2 kg mass travelling at 1 m/s, or a 1 kg mass travelling at 1.41 m/s. 4. The energy required to lift an apple up 1 m, assuming the a...
Zeptojoule
1. 160 zeptojoule is about one electronvolt.[citation needed] The minimal energy needed to change a bit of data in computation at around room temperature – approximately 2.75 zJ – is given by the Landauer limit.[citation needed]
Nanojoule
1. 160 nanojoule is about the kinetic energyof a flying mosquito.
Microjoule
1. The Large Hadron Collider (LHC) produces collisions of the microjoule order (7 TeV) per particle.[citation needed]
1 joule is equal to (approximately unless otherwise stated):[citation needed] 1. 107 erg(exactly) 2. 6.24150974×1018 eV 3. 0.2390 cal(gram calories) 4. 2.390×10−4 kcal(food calories) 5. 9.4782×10−4 BTU 6. 0.7376 ft⋅lb(foot-pound) 7. 23.7 ft⋅pdl(foot-poundal) 8. 2.7778×10−7 kW⋅h(kilowatt-hour) 9. 2.7778×10−4 W⋅h(watt-hour) 10. 9.8692×10−3 latm(litre...
In mechanics, the concept of force (in some direction) has a close analogue in the concept of torque (about some angle):[citation needed] A result of this similarity is that the SI unit for torque is the newton-metre, which works out algebraically to have the same dimensions as the joule, but they are not interchangeable. The General Conference on ...
A watt-second (symbol W s or W⋅s) is a derived unit of energy equivalent to the joule. The watt-second is the energy equivalent to the power of one watt sustained for one second. While the watt-second is equivalent to the joule in both units and meaning, there are some contexts in which the term "watt-second" is used instead of "joule", such as in ...
Slovakia is a developed country with an advanced high-income economy. The country maintains a combination of a market economy with a comprehensive social security system, providing citizens with universal health care, free education, and one of the longest paid parental leaves in the OECD. [12] .
Average human height by country. Below are two tables which report the average adult human height by country or geographical region. With regard to the first table, original studies and sources should be consulted for details on methodology and the exact populations measured, surveyed, or considered.
