Answer:These two forces are called action and reaction forces and are the subject of Newton's third law of motion. Formally stated, Newton's third law is: For every action, there is an equal and opposite reaction. The statement means that in every interaction, there is a pair of forces acting on the two interacting objects.

Answer:
G. It will take twice as long.
Explanation:
Let's call 
the original speed of the plane and 
the distance between Dallas and Pensacola. The time the plane originally takes to complete the flight is
In this problem, we are told that the plane encounters wind moving at half of its speed: 
, in the opposite direction. This means that the new speed of the plane is
And so, the time the plane takes now to complete the flight is
So, the plane takes twice the time as before.
Those forces are exactly equal.
Gravity always works as a pair of <em>EQUAL</em> forces ... one in each direction
between two masses. Your weight on the Earth is exactly the same as
the Earth's weight on you.
