because:
(a) Balanced forces act on the balloon
(b) Unbalanced forces act on the balloon
(c) Frictional forces act on the balloon
(d) Gravitational force acts on the balloon
9. Which of the following situations involves
the Newton's second law of motion?
(a) A force can stop a lighter vehicle as well as
a heavier vehicle which are moving
(b) A force exerted by a lighter vehicle on
collision with a heavier vehicle results in both
the vehicles coming to a standstill
(c) A force can accelerate a lighter vehicle more
easily than a heavier vehicle which are moving
(d) A force exerted by the escaping air from a
balloon in the downward direction makes the
balloon to go upwards​

Answer 1

Answer:

balanced forces act on the ballon

Explanation:

Balanced forces push the two sided of the ballon exerting pressure making ts shape change
