The battery has both a positive side and a negative side. The potential difference will be the potential of the positive end of the battery minus the potential of the negative end, which will result in positive potential, or power. This potential is what gives the electrons the ability to flow from the positive end to the negative end, or to make a current. While the outside of the insulated wire is the insulator, the inside of the wire has copper, which is the conductor of the current. So, this current will go through the copper of the wire (and not the insulator) from the positive side to the negative.
Answer:
Only 3 is true: The truck exerts the same amount of force on the car as the car exerts on the truck.
Explanation:
Compare the forces if the light truck is standing still when the car hits it.
1. The car exerts a greater amount of force on the truck than the truck exerts on the car. FALSE. This violates Newton 3rd Law of Action-Reaction.
2. The truck exerts a greater amount of force on the car than the car exerts on the truck. FALSE. This violates Newton 3rd Law of Action-Reaction.
3. The truck exerts the same amount of force on the car as the car exerts on the truck. TRUE. This is Newton 3rd Law of Action-Reaction. When there is a contact between objects, both exert on the other an equal and opposite force.
4. None of the answers correctly describes the situation. FALSE. 4 is true.
5. Neither exerts a force on the other. FALSE. If the car hits it then forces must come into play.
Hello
When all the stages of scientist method being covered. After that, you can to modify any theory according to the observations, measures, etc.

When magma reaches the top, it cools from the crust, it sinks back down to the core. Just like the water, the magma usually goes in a circular motion going up and down. Convection current is what moves plate tectonics/the crust.
