<h2>Answer:</h2>
The correct answer is option C which is chemical waste.
<h3>Explanation:</h3>
- Wind is the renewable source of the energy. The air has energy in it which is used to run the generator to produce electrical energy from the mechanical energy of wind.
- Wind energy is perfect in sense of pollution. It does not create any chemical waste because there is no conversion or production of chemical energy involve in this energy production.
- While bats and birds death is caused by the fans used to run generators and a huge noise is also created by the wind energy production.
Answer:
It takes 0.27 second to travel the distance of 100 yard
Explanation:
We can use the formula ( t = d / s )t = d / s = 91 m / 333 m/s = 0.27 s
Answer: The correct answer is "refrigeration".
Explanation:
Refrigeration is the process of rejecting heat from low temperature reservoir and transfers it to high temperature reservoir. Here, the heat is taken from the colder body and reject it to hotter body. The sink is at the lower temperature. The source is at the higher temperature.
In heat engine, the heat is transferred from high temperature reservoir to the low temperature reservoir. It is just opposite of the refrigeration.
Therefore, going against the natural flow of heat and moving thermal energy from a low temperature to a high temperature is refrigeration.
