How does the molecular structure of a water molecule affect its polarity?
2 answers:
Answer:
The molecular structure of water makes water to be a polar compound
Explanation:
A polar compound is a compound that has two poles. In this case, water will have negative and positive poles.
When a water molecule is formed, the two atoms of hydrogen do not just stay any where they like. Rather, they attach to the top of the oxygen atom, like rabbit ears as shown in the attachment below.
The hydrogen atom is positively charged, while the oxygen atom is negatively charged. This gives water its unique polar nature.
The top of the water molecule which has the hydrogen is now positively charged.
The bottom part of the water molecule which has the oxygen atom exposed is negatively charged.

Explanation:
The wind energy is the method of using the energy carried by the wind to generate the power. The wind energy is the considered as the conventional and clean source of energy.
The wind machines require the high power winds to rotate the blades of the windmill and produce power using the energy of the moving wind.
The winds blow at such high speed for a very small time during the day, the wind machine cannot be expected to work for a longer time during the whole day.
The wind energy can be obtained form a wind mill for a limited time unlike the other form of energy like thermal energy or even the solar energy. The thermal energy can be obtained at anytime due to burning of fuel whereas the solar energy can at least be obtained during the whole day time.
Thus, the wind machine on an average operates for a time of about .
