Answer:
Option (3)
Explanation:
Wind energy is directly derived from the wind. In the places where wind blowing is quite frequent, there wind mills are being set up, and the turbines in it rotates due to the prevailing wind. Due to this continuous motion of turbines, it collects the wind energy and it is being transferred into electrical energy.
It is cost-effective and does not produce any kind of pollution and is completely a renewable energy, that it can generated again and again.
It does have certain drawbacks also, because <u>the area may sometime do not experience constant wind, due to which it cannot store energy. So frequent wind blowing areas are the best place to set up windmills</u>.
Thus, the correct answer is option (3)
They travel through all medium types
D, It is a flow of protons, is the best answer. Electricity is the flow of electrons, not protons.
The required empirical formula of the silicon oxide is SiO2.
B) 1 Zn+ 2HCl--> 1 ZnCl2+1H2
This is balanced
