Answer: The choice of a submarine to either sink or float depends on the captain of that submarine. For a submarine to sink the captain just have to allow water to fill the water tank (lock), making the submarine more dense than the water it has displaced. For it to float, it just have to empty the water tank and allow air to fill it.
When a boat in a canal lock sank, the water level will rise, because the volume of the boat has displaced more water, and this displaced water will cause the water level to rise. The space occupied by an object in a water, is equal to the volume of water been displaced.
The correct answer is C. She can deceive her participants as long as she reveals the true nature of the study at its conclusion.
Explanation:
If the research involves human subjects, there are different ethical principles the researcher should follow to guarantee voluntary participation and the protection of participants and information. One of these principles is to be completely honest about the purpose of the research and the way participants will be part of it.
However, if revealing the purpose of the research can affect participation and create bias in the research, as it occurs in the case presented, the researcher can deceive participants during the research and reveal the purpose or nature of the research at the end. In this way, the researcher is still following ethical principles but avoids bias from participants. Thus, in the case presented Dr. Ethridge "can deceive her participants as long as she reveals the true nature of the study at its conclusion" (Option C).
Hinduism today is regarded nothing less than the progeny or an offshoot of Brahmanism, since Hindus got their name from Indus river, on the banks of which, the Aryans practised the Vedas. Hence, Hindus following the Vedas and its Brahman belief were seen as the first propellers of Hinduism.
Answer: The answer is C: There were massive increases in production due to the use of crops better suited to advance agriculture.
Explanation:
"Green revolution" is a term used for rapid increases in crops especially 'wheat' and 'rice' yields in developing countries which was introduced to Mexico and India by Norman Borlaug and Ms Swaminathan in the early 20th Century. They used improved crop varieties combined with the expanded use of fertilizers and other chemicals to boost crop production in developing countries. The goal of the Green Revolution was to increase the yields of wheat and rice by improving agronomic technology. This helped developing countries to overcome food defects.
