Juan inflates a balloon and then releases its end to let the balloon go free as air comes out. the balloon then flies around the room.

which statement describes how this example is an application of newton’s laws of motion?

according to newton’s first law of motion, the balloon continues moving until the forces on it are balanced.
according to newton’s third law of motion, the balloon is pushed forward as the air is forced out.
according to newton’s third law of motion, the balloon resists any change of motion unless an unbalanced force acts upon it.
according to newton’s second law of motion, the balloon exerts a force on the air, which exerts a force back on the balloon.

According to Newton's Third law, For every action there is an equal and opposite reaction and, the action and reaction acts on different body, not on the same body.

Now, as the air is forced out of the balloon (action force), the balloon moves forward in the opposite direction (reaction force). Both forces are equal in magnitude and opposite in the direction.

Hence, the statement 2 is correct: According to Newton's third law of motion, the balloon is pushed forward as the air is forced out.

answer: the rock sample is a sedimentary rock.

explanation:

it is given that:

mass of rock sample, m = 2.7 g

volume of rock sample,

so, density of rock sample will be

since, the density of rock sample is . hence, the rock sample is a sedimentary rock, whose densities varies between .

the answer is b i think
