Answer:
Concept of Conservation
Explanation:
Concept of conservation is the cognitive ability that helps a child to judge that some properties such as number of items, or volume will remain the same and invariant even if the shape or size of the container is changed or adjusted. This concept was posited by Jean Piaget, a psychologist who noted this ability in children between ages 7 to 11 during their concrete operational stage. He posits that the cognition of these age group will only focus on the noticeable attributes (e.g numbers, volume lenght) of an object rather than any change in size or other attributes
In this question the child lacks the concept of conservation with the inability to judge that the two beakers contain clearly identical volume of a liquid.
The grant available to third- or fourth-year college students majoring in physical, life, or computer sciences is the SMART Grant.
Two grant programs based on need were created by The Higher Education Reconciliation Act of 2005 for complementing the <em>Federal Pell Grant Program</em>:
- The first is called ACG (Academic Competitiveness Grants). Undergraduates from first and second year who fulfilled a rigurous high school curriculum can be awarded with it.
- The second is called SMART (National Science and Mathematics Access to Retain Talent Grants). Undergraduates from third, fourth and fifth year majoring in technical fields, critical foreign languages, or who are part of a qualifying liberal arts program can be awarded with it.
The answer would be letter C. The branch of ethical theory that considers the origin and meaning of ethical principles is known as Meta ethics. Meta ethics is one of the four branches of ethics and the rest are descriptive ethics, normative ethics, and applied ethics.
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.
