Answer:
D. It is caused by flowing negatively charged particles.
Explanation:
Current electricity is caused by flowing negatively charged particles. Current flows in a direction opposite the that of the charged particles.
The negatively charged particles can be electrons or ions in solutions.
As the electrons flows, current is generated in the opposite direction.
The potential difference is what drives the current and it is dependent on the available energy in the cell.
Answer:
hydrophilic
Explanation:
hydrophobic means it hates water so a hydrophobic material would separate from the water and just sit there (an example of this is oil)
Renewable resources are energy sources that can easily be utilized time and time again because they can be replaced quickly. Therefore, we can eliminate the third choice.
Now, you must distinguish whether nuclear energy, coal energy, wind energy, and geothermal energy are renewable or not.
Nuclear energy is not renewable because it requires many materials to obtain.
Wind energy is renewable because there is constantly wind, but coal energy is not renewable because coal takes millions of years to form.
Geothermal energy is renewable because there is constantly heat radiating from the Earth.
The answer is a renewable resource is one that can be replenished in a short amount of time. An example would be geothermal energy.
Hope this helps!!
