30m/s due north. Meanwhile‚ acceleration is definitely not the same as velocity or speed. Acceleration is the change in velocity in a certain amount of time. The factors affecting the terminal velocity of a falling object include: its mass‚ its surface area‚ the viscosity of a liquid and the height of where the object is dropped. In his First Law‚ Newton explained the effect of a net force‚ greater than zero‚ upon an object at rest. In his Second Law‚ Newton explains the effect of a force upon a

Mining is the process of digging beneath surface of the earth and extracting minerals and other useful geological materials. There are two main categories that mines fall into; surface mines and underground mines. Surface mines are effective at extracting minerals and geological materials that are close to the surface of the earth while underground mines are designed to extract minerals and geological materials that are deep beneath the surface of the earth. One of the most common materials that

known as splash erosion. This is the first stage in the erosion process. The impact of rainfall drops on the soil surface can break down soil aggregates as the impact of falling raindrops breaks up the topsoil. This erosion is caused by long lasting and less intense storms. Runoff can occur whenever there is excess water on a slope that can’t be absorbed into the soil or trapped on the surface. The method used to prevent erosion from raindrop splash erosion is stabilization. Temporary and permanent vegetation

Coal Mining Coal mining is taking coal out of the earth for use as fuel‚ and there are two types of it: surface and mountaintop mining and underground mining. Coal is one of the most important resources because of its ability to be a fuel. Surface mining is used when the coal is near the surface‚ and a process known as strip mining extracts it; this is literally tearing a strip out of the earth to expose the coal. This is a highly controversial method though because by taking so many strips

forming entire open rooms. Large pillars are left in a grid-like pattern to support the roof. The coal is cleared while digging and is taken back to the surface using conveyor belts. Crews then enter the room and insert metal rods into the roof four to six feet apart from each other in order to maintain the integrity of the topsoil and the surface. Around half of the coal in the mined area remains unexcavated in the form of the pillars‚ so at times‚ coal companies practice retreat mining. This is

Poverty is general scarcity or dearth‚ or the state of one who lacks a certain amount of material possessions or money.[1] Absolute poverty or destitution refers to the deprivation of basic human needs‚ which commonly includes food‚ water‚ sanitation‚ clothing‚ shelter‚ health care and education. Relative poverty is defined contextually as economic inequality in the location or society in which people live.[2][3]After the industrial revolution‚ mass production in factories made production goods increasingly
