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:A heuristic
Explanation:
A heuristic technique is the way in which we use a short cut to solve a problem or to make a decision by using practical reasoning which may not be logical or rational but still which is sufficient for us to make a quick decision or resolve an issues immediately or reach a short term goal. It helps us find a satisfying solution as quickly as possible.bit take away all the process of having to think deep. Heuristic can be a trial and error or an educated guess or using Intuition or just plainly common sense.
The Arctic is an ocean in the northern Hemisphere, including the North Pole. The Arctic Circe shares the name with the Arctic and it is also in the north, around the northern hemisphere. So the answer is north of the equator, as the Northern hemisphere is defined as north of equator.
In the context of team and organizational effectiveness, the Dunning–Kruger effect refers to people systematically overestimating their own performance in areas where they lack competence and readily dismissing any information to the contrary.
Answer: Option A
<u>Explanation:</u>
The Dunning-Kruger effects refer a situation in which people trust like they only smart and have more ability than in real scenario. However, person with less capability do not possess the more skills which required to realise their own inability.
Golem effect, a psychological effects in which less expectations are made upon individual either by superiors or by themselves, leading to poorer performance. Pygmalion effect defines the phenomenon where others' expectations for achieving the target by a person affects the aimed person's performance level.
Autler towns’ effect is related with the ohysic term for the effect and result to an oscillating electric field. From this, concluding that Option A is correct to the given statement.
Answer:
Business
Explanation:
As with many civilizations it goes through different stages and social norms. The Middle Ages was just a phase in history as are many others. While there were many reasons for the shifting of the Middle Ages on to the Renaissance, the most poignant of that was money. During this time, the feudal system, which was the reception of land for services was on the decline. In this same time the Church declined and this gave way for the merchants to take power that was available. This influx of money created a new and refreshing class of people called the Middle class ending the dark ages.
