Old-fashioned gristmills depend on water to grind grain into flour. Water is a source of energy for a gristmill. Which statement correctly describes why this is so?

 

• Moving water produces wind that turns the gristmill, so it grinds the grain

   

   

• Warm water heats the gristmill, causing it to move and grind the grain.

• Water produces electricity to turn the gristmill, so it grinds the grain.

• Moving water turns the gristmill, causing it to move and grind the grain.

A student is experimenting with two charged objects. She holds the objects close to each other, but she makes sure they never touch.

Which is the only hypothesis about the two objects that Sidney would find to be true?

• If the first object has a positive charge and if the second object has a negative charge, then the objects push away from each other.

• If both objects have a negative charge, then the objects pull toward each other.

• If the first object has a negative charge and if the second object has a positive charge, then the objects push away from each other.

• If both objects have a positive charge, then the objects push away from each other.
