From the following options presented in the problem, the only global city in the region of Russia and its neighboring countries would be A. Moscow.
Of the options presented, between Moscow, Kiev, St. Petersburg, and Tashkent, the only global city would be Moscow. Kiev and Tashkent aren't located in Russia. This leaves Moscow and St. Petersburg. Although some would argue that St. Petersburg would be the answer, it is a fact that St. Petersburg is yet to be called as a global city. Moscow, on the other hand, is already declared one though its activities as one is limited. Both are solely affected as to Russia's approach in the overall development of the country and is yet to show progress.
Temperature can affect malleability. For example, the metal zinc, which is brittle when below 300 degrees F, but becomes very malleable when heated above 300 degrees.
Answer: Point D cannot be the orthocenter because the orthocenter of an obtuse triangle is located outside the triangle.
Explanation: because ABC is an obtuse triangle
Answer:
The current theory for star formation is that stars form within giant molecular clouds. Stars form where there are dense cores within clumps of gas and dust in these clouds. The formation of a protostar involves the rapid collapse of infalling gas onto a dense core due to gravity. As a protostar shrinks, its rate of spin decreases. This allows subsequent infalling gas to accumulate at the equator of the protostar; this material tends not to accummulate at the protostar's poles due to its spinning motion. As the protostar continues to evolve, it emits infrared radiation. When it has nearly reached its final mass, it is called a Wolf-Rayet star. These objects produce strong stellar winds.
