What wind turbines to hydroelectric dams and ethanol plants have in common?

All three are forms of renewable energy.

Wind turbines utilize the wind to generate power, hydroelectric dams also do the same (although most states have stopped using them since they're bad for the environment)

Ethanol, a substitute for gasoline, comes from corn, which can be grown in farms throughout America.

i just did an experiment like this in my science class. also the answer is yes, it will get separated because they are two opposites meaning if they are opposite they can not attract.

hope this .!
