An octopus propels itself through the water by ejecting water through a funnel in its body. How does this demonstrate Newton’s third law?(1 point)

When the octopus ejects the water out, the water acts with an equal force on the octopus in the opposite direction.

When the octopus ejects the water out, the water acts with an equal force on the octopus in the same direction.

The correct answer is: "When the octopus ejects the water out, the water acts with an equal force on the octopus in the opposite direction."
To understand why this is an example of Newton's third law, we need to recall Newton's third law of motion, which states that for every action, there is an equal and opposite reaction.
In this case, the action is the octopus ejecting water through its funnel. As the octopus forcefully expels water, it creates a backward-directed momentum. According to Newton's third law, there must be an equal and opposite reaction. This means that the expelled water, as a reaction, exerts an equal force on the octopus, but in the opposite direction.
So when the octopus ejects the water out through its funnel, the expelled water exerts an equal force on the octopus, propelling it forward through the water.
