Answer: The law of conservation of energy states that energy can neither be created nor destroyed - only converted from one form of energy to another.
Explanation:
Density is calculated as mass per unit volume. In this case, since the material has a mass of 47 grams and we have the volume of 15 cm^3, we can simply divide the values:
Density = 47 grams / 15 cm^3 = 3.1 g/cm^3
Therefore, the material has a density of 3.1 g/cm^3
When one object is rubbed against another, static electricity can be created. This is because the rubbing creates a negative charge that is carried by electrons.
You never gave us an answer, so therefore, we can't answer this question.
