If a ball is accelerating down through the air with no horizontal motion, what must be true about the net forces acting on the ball? (a) The net force on the ball is directed upward. (b) The net force on the ball is zero. (c) The gravitational force is greater than the drag. (d) The drag is greater than the gravitational force.

The net force on the ball is zero.

Explanation:

The net force and the acceleration on the falling skydiver is upward. An upward net force on a downward falling object would cause that object to slow down. The skydiver thus slows down. As the speed decreases, the amount of air resistance also decreases until once more the skydiver reaches a terminal velocity.A force can cause a resting object, or it can accelerate a moving object by changing the object's speed or direction. When the forces on an object are balanced, the net force is zero and there is no change in the object's motion. When an unbalanced force acts on an object, the object accelerates.

here are some information of the future of geothermal energy:

-the future of geothermal energy can pretty much be summed up with a single word: more

-scientists plan in going deeper than 120 meters

-we are hoping that one day, we will get all of our energy from renewable energy sources such as geothermal energy

hope this !
