Explanation:
What context are you asking it in?
The answer could be the electromagnetic interaction if you're talking about the 4 fundamental interactions, or ionic interaction, or electrostatic interaction.
Answer:
Option D. Activation energy
Explanation:
Activation energy is the minimum energy required to start a chemical reaction. For a reaction to occur, the reactants must possess energy equal or greater than the activation energy else the reaction will not occur.
Surface of a sphere=4πr²
volume of a sphere=(4/3)πr³
Data:
surface area =432 m²
volume=864 m³
ratio of surface area to volume=surface area / volume
ratio=432 / 864 =0.5
Answer. The ratio would be 0.5
Answers with Explanations:
1. Why is knowledge of mineral properties important?
Knowledge of mineral properties is important because it <u>helps scientists know about the earth's history, particularly when it comes to "rock formations."</u> It is also essential in order to know which minerals are economically important.
2. Which properties might be useful in construction?
Minerals have many physical properties (<em>color, crystal form, hardness, luster, density, cleavage and fracture, etc.) </em>
When it comes to construction purpose, the mineral's malleability is very important. This is the reason why "iron" is one of the most important minerals being used in buildings. It's <em>malleability</em> allows it to be framed into "steel," which is then used to make even bigger infrastructures and skyscrapers.
3. In jewelry-making?
When it comes to "jewelry-making," the <em>hardness </em>and <em>luster</em> of the mineral may be used as a basis. For example, the diamond can be determined from the rest of the minerals because it is the hardest and it has a brilliant-kind of luster.
