Accretion of material due to supermassive black holes in galactic cores leads to intense active galaxies luminosity.
Explanation:The center of the galaxies has a high luminosity as compared to other parts postulated to be emitted by something other than the stars because of its intense luminosity. They are electromagnetic radiation source which is useful for discovering objects from outer space.
They can be observed by gamma rays, ultra-violet, radio, microwave, x-rays, infrared, and many more similar. Classification of an active galactic nucleus which is based on their observed characteristics has been made and the quasar is the powerful one.
What is the name of the mountain range on the bottom of the atlantic ocean?
ANSWER:
The Mid Atlantic Range is the mountain range at the bottom of the Atlantic Ocean.
EXPLANATION:
This mountain range is a 'mid-ocean ridge' which is formed by the movement of tectonic plates. This mountain range is the 'longest mountain range of the world' and is a constructive or divergent tectonic plate. The mountain range is almost '40,000 km long' and is also an unbroken mountain range. The mountain range also features many active volcanoes along its length.what natural resources makes many nations of this region wealthy ?

In December 1979, Soviet troops marched into Afghanistan to help put down a revolt at the request of _____.
In an attempt to stabilize the turbulent political situation in Afghanistan, the Soviet Union sends 75,000 troops to enforce the installation of Babrak Karmal as the new leader of the nation. The new government and the imposing Soviet presence, however, had little success in putting down antigovernment rebels. Thus began nearly 10 years of an agonizing, destructive, and ultimately fruitless Soviet military intervention in Afghanistan.
Ironically, Karmal overthrew and murdered another Afghan communist, Hafizullah Amin, to take power. Amin’s government became unpopular and unstable after it attempted to install a harsh communist regime, declared one-party rule and abolished the Afghan constitution. Muslims in the nation rejected his rule and formed a rebel force, the Mujahideen. When it became apparent that Amin could not control the rebellion, Soviet troops intervened and put a puppet ruler, Karmal, into power. For the Soviets, political turbulence in this bordering nation, which was viewed by some officials as a potentially useful ally pursuing its interests in the Middle East, was unacceptable.
The Soviet intervention cost Russia dearly. The seemingly endless civil war in Afghanistan resulted in thousands of Soviet dead and untold monetary costs. It also brought an abrupt end to the era of détente between the United States and the Soviet Union that began during the Nixon years. In response to the Soviet intervention, President Jimmy Carter withdrew the SALT II agreement from consideration by Congress. The treaty, which had been signed in June 1979, was designed to establish parity in nuclear delivery vehicles between the United States and the Soviet Union. Carter also halted grain shipments to the Soviet Union and ordered a U.S. boycott of the 1980 Olympics that were to be held in Moscow.
The answer for Gradpoint is "the Afghan government".

Which of jupiter's moons is almost completely molten inside?
Explain why some partly molten material rises toward earths surface
Sometimes, some partly molten material rises towards the Earth's surface because either it gets added to the magma in the due course of the upward movement of magma and the magma doesn't get enough to melt it completely, or the material consists of elements with extremely high melting points.
Explanation: The magma carries molten material from the mantle towards the surface of the Earth. In its course of rising up, sometimes some materials get added to it after it is just about to reach the Earth's surface. Such material doesn't melt completely and reaches the surface in a partly molten form. In other cases, the magma consists of elements with melting points above 1200° Celsius to 1300° Celsius. Such materials sometimes reach the Earth's surface in a partly molten form.what is the size and location of the korean peninsula ?

As many as ____% of individuals with eating disorders today are males.
Approximately 10% of individuals with eating disorders are males, including serious conditions such as anorexia nervosa and bulimia nervosa. Studies show that males can also have a distorted body image, such as muscle dysmorphia, requiring prevention and tailored treatment.
As many as 10% of individuals with eating disorders today are males. This estimation includes disorders such as anorexia nervosa and bulimia nervosa which, while historically associated more with females, significantly impact males as well. The lifetime prevalence rate of bulimia nervosa, for example, is estimated at around 1% for women and less than 0.5% for men. A comprehensive study involving over 9,000 young males in the United States found that approximately 5.5% of them manifested elevated eating disorder risk. It's essential to recognize that eating disorders in males often involve a distorted sense of body image, including conditions such as muscle dysmorphia, where there is an extreme desire to increase muscularity. Due to the seriousness of these conditions and the potential for high mortality rates, comparable with opioid addiction, prevention and appropriate treatment tailored to the physical, emotional, and social needs are crucial.
Assume(s) that the expansion rate of the universe always stays the same. predict(s) that the universe is expanding today. predict(s) that the universe will someday contract. predict(s) that the average density of mass in universe is exactly the critical density. predict(s) that the universe is expanding faster now than it was in the distant past.
Physics dictates that the expansion of the universe and its critical density determine whether the universe will expand indefinitely or eventually contract. Current evidence indicates that the universe's mass density is below critical levels, suggesting continuous expansion, especially with the discovery of dark energy accelerating the expansion.
Explanation:The concept of the expansion of the universe is a fundamental principle in cosmology, which is a branch of astronomy and thus falls under the subject of Physics. The expansion rate of the universe and its relation to critical density determine the various possible outcomes for the long-term evolution of the universe. According to models, if the actual mass density of the universe is greater than this critical density, the universe will eventually stop expanding and begin to contract, leading to a closed universe. Conversely, if the density is less than the critical density, the universe will continue to expand indefinitely. Moreover, recent observations suggest that dark energy is causing the universe to expand at an accelerated rate, which indicates that we live in a universe that will continue to expand forever.
The critical density is the mass per unit volume that, if achieved, would result in the expansion rate slowing down and eventually halting after an infinite amount of time. However, current observational evidence implies the universe's mass density is below this threshold. The universe is considered homogeneous and isotropic on a large scale, meaning that it looks the same in every direction and at every place. This assumption allows us to use simplified models to describe the universe's expansion and predict its fate. Although earlier models suggested a potential for future contraction, the discovery of dark energy has led to a consensus that the universe will likely expand forever.

Explanation:
In two years __ people died from famine in china
Answer:
In two years 15 million people died from famine in China.
Explanation:
The Great Chinese Famine marked the period between 1959 and 1961 as one of the most horrendous in the history of China. The famine claimed around 15 million lives. Mao Zedong, the then communist ruler of China modified the policies and abstained the farmers from owning the agricultural land. The ones who denied to abide with this unjust policy of Mao were punished brutally. These activities led to the emergence of a great famine which is today's date called 'The Great Chinese Famine'.Which of the statements explains why glaciers create valleys with a distinctive shape?
What is the name for the elevation difference between two adjacent contour lines? A. Contour interval B. Contour loop C. Elevation D. Slope
The elevation difference between two adjacent contour lines is known as the 'Contour interval', and it specifies the vertical change one would experience across the map's surface. So, option A is correct.
The name for the elevation difference between two adjacent contour lines on a topographic map is A. Contour interval. A contour interval represents the constant difference in elevation between any two successive contour lines. For example, if the difference in elevation is 100 feet between two bold lines on a map and there are five lines between them, the contour interval would be 20 feet (100 ft / 5 lines = 20 ft between lines). This means that each contour line you cross while moving on the map corresponds to a vertical change of 20 feet. The contour interval can typically be found in the map's legend.
