It depends on the diameter of the "earth". If it is exactly the same size as Earth, then a 7,917.5 mile long wire would be required.

"The strongest current was found around the galaxy 3C303, whose core is the origin of a massive matter jet."       (POPULAR SCIENCE, The Strongest Electrical Current)

     This galaxy is admitting 1018 amps. This equals one TRILLION bolts of lighting.

The Earth's magnetic field at its surface ranges from 35 to 65 microteslas.

6. Where is the North European Plain?
guajiro [1.7K]

Answer:

The western and central European section of the plain covers all of western and northern France, Belgium, The Netherlands, southern Scandinavia, northern Germany, and nearly all of Poland; from northern France and Belgium eastward it commonly is called the North European Plain.

Explanation:

The North European Plain is a European region that covers Denmark, Poland, Germany, Belgium, Holland, and small parts of northern France and the Czech Republic. Some research accounts also include the southern United Kingdom, east Russia, Baltic States like Estonia, Latvia, Lithuania, and Belarus as part of this expansive plain. The North European plain also has lowly elevated plains tucked between the Central European Highlands on the south and on the coastlines of the Baltic Sea and North Sea to the north. The Baltic and the North Sea are divided by the North Jutland Peninsula which is also the nation of Denmark. The Great European Plain is formed where the North European Plain connects to the East European Plain. The Northern European Plain also occupies the territory under the Baltic Sea. Due to the plain's unique surface features, its geological structures are keenly studied by researchers.

Features

As part of the Great European Plain, the North European Plain lies below 500 feet in altitude, and has a relatively flat terrain. As a result, drainage is poor and frosty deposits cover much of the region and plain. The North European Plain also has several rivers like the Rhine, Oder, Weser, Elbe and Vistula. Along the Rhine River in the Netherlands, there is a well developed transport system, and a vibrant agricultural area making the area around it be densely populated. The plain is amongst the most fertile lands that are utilized for commercial farming in the world. There are also tiny farms strewn in the countryside of the North European Plains. The temperate climate and the average amount of rainfall in the North European Plain allows for growth of seasonal crops like maize, wheat, and rye. This makes the plain in the North European wheat belt region. Due to the plain’s fertility and flat terrain, it is among the most densely populated territories in Europe. The rivers that crisscross the North European Plain also draw in a large human population due to guaranteed water supply.

eduard

Answer:

Quartz is not pure in this rock.

Explanation:

When quartz shows effervescence in contact with an acid, it means that it is not in its pure state, but rather related to other substances that may be cementing the quartz. This effectiveness is caused by substances that do not react like quartz, such as calcite.

In this case, we can conclude that in relation to the calcium-rich rock shown in the question above, the calcium is not pure, but it is likely to be related to calcite, or other material that does not react to acid.
