Environmental Impacts: Coal vs. Uranium, Climate Change, Acid Rain
Environmental Effects of Coal and Uranium as Power Sources
Coal and uranium are both mined, which creates landscape damage and harmful tailings that can contaminate waterways. Uranium generates more power than coal by weight or volume, so less of it needs to be mined. Combusting coal for electricity emits sulfur and nitrogen oxides that contribute to acidic deposition. Coal burning also emits particulate matter, which threatens human health and creates carbon dioxide and other greenhouse gases that

Motion
Superposition
When a mobile body is subjected to two simultaneous movements, the kinematic variables (position, velocity, and acceleration) are obtained by adding the kinematic variables of the two movements.
Principle of Independence
When a mobile body’s motion is composed of two simple movements, its position at a given time is independent of how the simple movements operate, whether simultaneously or successively.
Parabolic Motion
Parabolic motion is composed of one rectilinear uniform motion

The Mosque-Cathedral of Córdoba
The Mosque-Cathedral of Córdoba is the result of four stages of construction. It serves as a prayer room for believers and consists of 514 columns. The columns from the time of Abderrahman I varied in material, including marble and granite, resting on pedestals that differ in height and type of molding. Their stems are smooth or fluted, vertical or spiral. To provide the necessary height and lightness, picture rails with scrolls rolled up on themselves (roll modillions)

Risks Associated with Volcanic Activity
Explosions of the Volcano: This occurs when highly viscous magma causes violent explosions, ejecting clouds loaded with liquid magma fragments and solid rock fragments from the vent, or recently formed rocks. These rocks form a cloud called a pyroclastic flow, which moves at high speed down the slopes, dragging everything in its path.
Rain of Pyroclastic Materials: In volcanoes that eject a large amount of fine material, the material is entrained by the exiting

Labor Movement’s Fierce Fight for a Better Life
In the 19th century, workers began to improve their working conditions by destroying the machines (Luddism) to which they blamed their situation. From the first half of the 19th century, doctrines and organizations emerged.
The Principal Doctrines
Thinkers analyzed society and began to advocate for a different society. This encompassed two ideological currents:
- Marxism was the ideology that had the most influence on the proletariat. The key to capitalist
Bosnia and Herzegovina: A Geographical and Geological Overview
Geography of Bosnia and Herzegovina
The Ivan Sedlo saddle, found between the mountains of Bitovnja and Bjelašnica, connects the two major parts of the country: the more populated and abundant in forests and land, Bosnia in the north, and the smaller, rocky Herzegovina in the south. The natural border between Bosnia and Herzegovina is the mountain range of Vran, Raduša, Vranica, Bitovnja, Bjelašnica, Treskavica, Zelengora, and Maglić.
- Northernmost part: Bosanska Dubica
- Southernmost part: Podtirovnik
