<span>The question is asking for the reason why water is considered a polar molecule. The correct option is A. Water molecule is a polar molecule because it has one side which is positively charged and the other side is negatively charged. Each molecule of water has two hydrogen atom and one oxygen atom. The slight negative charge near the oxygen atom attract nearby hydrogen atoms from water and the slightly positive charge of the hydrogen atom attract oxygen atom. The attraction set up by these charges are responsible for the polarity of water molecules. </span>
Answer:
Density is the ratio between the mass and the volume of a body. Relative density, on the other hand, is the ratio between the density of an object (substance) and the density of some other reference object (substance) at some given temperature.
Explanation:
<h2>Answer:</h2>
The feature of an object affects its weight are given below
- mass of the object
- location of the object
- how much force Earth exerts on the object
<h2>Explanation:</h2>
Weight of the body is equal to the product of gravity and the mass of it so weight is dependent upon mass. The more the mass, the more is the weight. In the same way the location of the object differs if the location is far from the earth. Similarly gravity is the force with which earth attracts everything towards its center therefore we can say that if the object moves away from the earth center the weight decreases eventually..
