Massachusetts

Massachusetts ⁱ/ˌmæsəˈtʃuːsᵻts/, officially the Commonwealth of Massachusetts, is a state in the New England region of the Northeastern United States. It is bordered by Rhode Island and Connecticut to the south, New York to the west, Vermont and New Hampshire to the north, and the Atlantic Ocean to the east. Massachusetts is the 7th smallest state by land area, but the 15th most populous and the 3rd most densely populated of the 50 states. With an estimated 6.8 million residents in 2015, it is the most populous of the six New England states and has the nation's sixth highest GDP per capita. The capital of Massachusetts, as well as the state's largest city, is Boston. The state features four separate metropolitan statistical areas: the Boston-Cambridge-Quincy metropolitan area in the east, the Worcester metropolitan area in the center, the Springfield metropolitan area in the west, and the Barnstable metropolitan area in the southeast. Over 80% of Massachusetts' population currently lives in the Greater Boston Combined Statistical Area.

Mass

In physics, mass is a property of a physical body. It is generally a measure of an object's resistance to changing its state of motion when a force is applied. It is determined by the strength of its mutual gravitational attraction to other bodies, its resistance to being accelerated by a force, and in the theory of relativity gives the mass–energy content of a system. The SI unit of mass is the kilogram (kg).

Mass is not the same as weight, even though we often calculate an object's mass by measuring its weight with a spring scale instead of comparing it to known masses. An object on the Moon would weigh less than it would on Earth because of the lower gravity, but it would still have the same mass.

For everyday objects and energies well-described by Newtonian physics, mass describes the amount of matter in an object. However, at very high speeds or for subatomic particles, special relativity shows that energy is an additional source of mass. Thus, any stationary body having mass has an equivalent amount of energy, and all forms of energy resist acceleration by a force and have gravitational attraction.

Clash of Clans

Clash of Clans is a freemium mobile MMO strategy video game developed and published by Supercell.

The game was released for iOS platforms on 2 August, 2012, and on Google Play for Android on 7 October, 2013.

Gameplay

Clash of Clans is an online multiplayer game in which players build a community, train troops, and attack other players to earn gold and elixir, and Dark Elixir, which can be used to build defenses that protect the player from other players' attacks, and to train and upgrade troops. The game also features a pseudo-single player campaign in which the player must attack a series of fortified goblin villages.

Buildings

To earn and store gold and elixir, players must build gold mines and gold storages and elixir collectors and elixir storages, respectively. Elixir is used to train new troops, carry out research in the laboratory to upgrade troops, to re-load X-Bows (available from Town Hall 9) and to build and upgrade certain buildings, mostly pertaining to buildings used in attacking another player's base. Gold is used to build defensive buildings and to upgrade the town hall, which allows access to more buildings and higher levels for existing buildings. At higher levels, dark elixir becomes available; this type of elixir is used to train and upgrade dark elixir troops and heroes, create dark spells, and fuel the Inferno Tower, a defensive building that is available only at Town Hall 10. To earn and store dark elixir, players must build dark elixir drills and dark elixir storages.

North Korea ( listen), officially the Democratic People's Republic of Korea (DPRK; Chosŏn'gŭl: 조선민주주의인민공화국; hancha: 朝鮮民主主義人民共和國; MR: Chosŏn Minjujuŭi Inmin Konghwaguk), is a country in East Asia, in the northern part of the Korean Peninsula. The name Korea is derived from the Kingdom of Goguryeo, also spelled as Koryŏ. The capital and largest city is Pyongyang. North Korea shares a land border with China to the north and northwest, along the Amnok (Yalu) and Tumen rivers, and a small section of the Tumen River also forms a border with Russia to the northeast. The Korean Demilitarized Zone marks the boundary between North Korea and South Korea.

Korea was annexed by the Empire of Japan in 1910. After the Japanese surrender at the end of World War II in 1945, Korea was divided into two zones by the United States and the Soviet Union, with the north occupied by the Soviets and the south by the Americans. Negotiations on reunification failed, and in 1948 two separate governments were formed: the Democratic People's Republic of Korea in the north, and the Republic of Korea in the south. An invasion initiated by North Korea led to the Korean War (1950–53). Although the Korean Armistice Agreement brought about a ceasefire, no official peace treaty was ever signed. Both states were accepted into the United Nations in 1991.
