The mechanical energy of an object is equivalent to the sum of its potential and kinetic energy. If the helicopter is grounded, then its mechanical energy will be 20 J. If it is in the air, then its potential energy will be calculated using:P.E = mghAnd then added to the kinetic energy to obtain mechanical energy.
Answer:
The answer is working memory.
Explanation:
Working memory is a memory system which allows a person to process and manipulate information. Although it's sometimes used interchangeably with <u>short-term memory</u>, the difference is that working memory allows the person to use the information in a practical way<u>,</u> while short-term memory simply stores it. For example, a mathematical formula stored in the short-term memory will be used by working memory when solving a problem in a test.
What do you mean by items, you mean weapons?
Answer:
D. They do not want to live near towers that transfer electricity.
Explanation:
The defense mechanism that humans have tend to react stronger when they feel that perceived threat is close to their proximity and they can experience the negative effect in a short term period.
This what might influence people's preference on living near Power plants.
The damage that might be created from malfunctioning power plant have a high chance to create catastrophic damage within a short period of time. This perception of threat often overweigh the potential benefit that the plants and influence their decision regarding whether or not they want to live near wind power plants.
