PM me for full answer, please. If it's not too late.
The answer is A. Newton's third law of motion states that for every action, there is an equal and opposite reaction. A rocket exerts a large force on the gas that is in the rocket chamber (action). The gas thus exerts a large reaction force forward on the rocket (reaction). The large reaction force is called thrust.
On the ball, there is mg of net force.
<h3>How would one describe air resistance?</h3>
- Air exerts a force known as air resistance. The force works in the opposite direction of an object traveling through the air.
- While a sports vehicle with a streamlined design will encounter reduced air resistance and experience less drag, the automobile will be able to move more quickly than a truck with a flat front.
<h3>What Causes Air Resistance?</h3>
- Air resistance, also referred to as "drag," is a force brought on by air. When air specks collide with an object's front, it slows down.
- The more air particles that impact the object and the larger its surface area, the more resistance it faces.
