1. A balloonist drops an apple weighing 1.5 N over the side of the balloon's gondola. As it falls and increases speed, the drag force from the air upward on it increases. When the upward force is 0.7 N, what is the direction and magnitude of the net force on the apple?

9.8 N downward

1.5 N downward

0.7 N upward

0.8 N downward

I think its B, correct me if I am wrong

net force=mg-.7 =.8 dowward

To determine the direction and magnitude of the net force on the apple, we need to consider the different forces acting on it.

The weight of the apple is given as 1.5 N, and it acts downward due to gravity.

The drag force is given as 0.7 N, and it acts upward due to the force of air resistance.

To find the net force, we need to subtract the upward force of air resistance from the downward force of gravity:

Net force = Weight - Drag force

Net force = 1.5 N - 0.7 N

Net force = 0.8 N

So, the net force on the apple is 0.8 N. However, the direction of the net force depends on which force is greater. Since the upward drag force from the air (0.7 N) is less than the downward weight force (1.5 N), the net force will be directed downward.

Therefore, the correct answer is option D: 0.8 N downward.
