Generally considered to be the first great war of the 20th century, the conflict saw Russia and Japan – the two dominant nations in north-east Asia – battle for control over Korea and Manchuria.
<span>But why did the war break out, and what is its historical significance? Here, Dr Philip Towle from the University of Cambridge tells you everything you need to know about the conflict.</span>
Answer:
An educated guess or a presumption based on review of the research literature
Explanation:
A hypothesis is an educated guess or a presumption based on review of the research literature.
It is a proposition based on reasoning without any assumption of its truth, it enables the researcher to have a better understanding about the subject matter of the study.
The correct answer is economic globalization. This process is happening since the 1950s and includes the increase in international trade, global capitalism and free markets. Since global migration thanks to the invention of airplanes has rapidly been increasing, it had been easier than ever due to the technological evolution.
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:
Relational aggression
Explanation:
Relational aggression refers to the non-physical aggression against someone else in order to weaken their credibility or social status or improve their own social status. It is also called mean girl phenomena because it is often reflected in the competition between teenage girls. It could break down the one's self-esteem and trust and trigger a host of mental health issues such as anxiety, stress, depression, eating disorders, etc.
