Answer:
Option A, Self-determination, is the correct answer.
Explanation:
In context to modern international law, the right of self-determination is a cardinal policy, which binds an authentic understanding of the norms of the Charter. According to this right, people, based on reverence for the source of equal rights and adequate equality of occasion, have the right to unobstructedly choose their self-determination and foreign executive status with no intervention.
I believe the answer is: Reference group
Reference group refers to the group that become subjects of comparison to another group of individual.
Most people use this reference group to measure our own worth (for example, if you want to know whether you a bad or good guitar player, the reference group that you would most likely use would be famous band member) , and this might influence the formation of our identity in the future.
Hello. This question is incomplete. The full question is:
"Technological improvements and reduced equipment costs have made converting solar energy directly into electricity far more cost-efficient in the last decade. However, the threshold of economic viability for solar power (that is, the price per barrel to which oil would have to rise in order for new solar power plants to be more economical than new oil-fired power plants) is unchanged at thirty-five dollars. Which of the following, if true, does most to help explain why the increased cost-efficiency of solar power has not decreased its threshold of economic viability?
(A) The cost of oil has fallen dramatically. (B) The reduction in the cost of solar-power equipment has occurred despite increased raw material costs for that equipment. (C) Technological changes have increased the efficiency of oil-fired power plants. (D) Most electricity is generated by coal-fired or nuclear, rather than oil-fired, power plants. (E) When the price of oil increases, reserves of oil not previously worth exploiting become economically viable."
Answer:
(C) Technological changes have increased the efficiency of oil-fired power plants.
Explanation:
Economic viability is able to reveal the degree of acceptance of consumers in relation to a specific product. This viability is important to understand how the product will be received in the market and how profitable or not it can be for those who produce it.
Economic viability is usually greater when the cost and benefit ratio of the product or service is favorable, however this is not always the case.
Regarding the use of solar energy, although technological changes have made the installation and equipment of this type of energy more cost-effective, these technological changes have also increased the efficiency of oil plants. As a result, the economic viability of solar energy has declined.
Answer: D. to the right
Explanation: A wave is transporting energy from left to right. The particles of the medium are moving back and forth in a leftward and rightward direction.
