A a wire, a wire is connected between the positive and negative ends of the eletrical energy source and connects all the components in between.
I think everytime they swim away, the water pushes the enemy back, which makes the octopus go faster. Every action has an equal and opposite reaction. Hope this helps.
Option A is correct answer
the mass would remain the same and the weight would change. mass defines the actual amount of an object, while weight is the force gravity has on that object. gravity is different on the moon and the earth therefore the weight will change
When you talk about "the strength of an electric force" in middle school, I'm pretty sure you're talking about the force between two electrostatic charges that either pulls them together or pushes them apart.
The strength of that force depends on
-- the product of the amounts of charges on the two charged objects
-- the distance between the centers of their charges.
