Consider a ball standing in the bed of a pickup truck, which is coated with ice. You can consider the force of friction between the ball and the truck to be zero. The truck is initially at rest, and then accelerates to the right, moving along a flat road. As seen from a stationary observer (watching the truck move to the right), the ball: 1) moves to the right at the same rate as the truck, so it doesn't slide moves to the right, but not as quickly as the truck is moving to the right, causing it to slide towards the back of the truck moves to the left, as the truck moves to the right, causing the ball to slide towards the back of the truck.
2) does not move left or right, but the back of the truck moves towards the ball.

explanation:

considering the bohr theory, the type of connection that requires the transfer the answer conuldn't be right

i think the answer would be reserve.

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.
