Question

in the balloon lab, what is propelling the balloon forward along the string? * 1 point
air is exiting the balloon as a reaction to the balloon moving forward along the string
the balloon is moving forward along the string in reaction to air exiting the balloon
air exiting the balloon and the balloon moving forward are both action forces. there is no reaction
which of the following statements is true? * 1 point
the force of the balloon moving forward will always be equal to the force of air exiting the balloon in the opposite direction
the force of the balloon moving forward will always be stronger than the force of air exiting the balloon in the opposite direction
the force of the balloon moving forward will always be weaker than the force of air exiting the balloon in the opposite direction

Explanation:

Según la tercera ley de Newton (ley de acción - reacción), cuando el aire sale del globo (acción), el globo se mueve hacia adelante (reacción). Además, las fuerzas de acción y reacción son iguales en magnitud y opuestas en dirección.

Answer:

• Primera pregunta: The balloon is moving forward along the string in reaction to air exiting the balloon
• Segunda pregunta: The force of the balloon moving forward will always be equal to the force of air exiting the balloon in the opposite direction
