An octopus propels itself through the water by ejecting water through a funnel in its body. How does this demonstrate

Question

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

Answer 1

The correct explanation of how the octopus propelling itself through water demonstrates Newton's third law is:

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

This is consistent with Newton's third law, which states that for every action, there is an equal and opposite reaction. When the octopus pushes the water out, it experiences an equal and opposite force that propels it forward.
