How does Newton's third law explain how a rocket is launched upward? O A. As the fuel burns, the rocket's mass decreases, allowing it to fly
faster and faster.
O B. Gases from burning fuel are pushed out of the bottom of the
rocket, and these gases push back on the rocket with an equal
amount of force.
C. When the rocket's speed increases, the amount of force needed to
move it decreases.
D. As the rocket accelerates upward, the air resistance pushing
against the rocket decreases.

glen is correct.

step-by-step explanation:

glen is correct because when you multiply 4 * 2 = 8.

and 4 * 3 = 12.

air exerts forces on falling objects near earth’s surface.

explanation:

the term 'free falls' refer to object that are falling towards the earth, in a situation in which gravity is the only force acting on the object.

for an object in free fall, the acceleration is constant (g, the gravitational acceleration), and so the velocity of the object constantly increases.

for objects near earth's surface, there is always another force acting on the object: the resistance due to the air. this force is opposed to the direction of fall of the object, and it is proportional to the velocity of the object, so as the object falls down, this force increases up to a point when it balances the force of gravity, and the object continues its motion at constant velocity (called terminal velocity). since in this case gravity is not the only force acting on the object, we are not in a situation of free fall.
