Answer:
The force must be in the same direction as the object’s motion
Explanation:
Force is a physical quantity.
It is defined as the force applied to a body to move it in the direction of the force applied.
Force = mass x acceleration.
- Force results in the acceleration of a body.
- Force causes the change in position of a body and it moves it towards the direction of the applied force.
- A force is a vector quantity having both magnitude and direction.
So, option is C is the correct choice.

Answer:
C. effusion because there is a movement of a gas through a small opening into a larger volume
Explanation:
Effusion makes fluid/gas molecules move to the container with less pressure or larger volume. In diffusion, the movement should work two ways even though one side might receive more. But in effusion, the movement is rather one way.
This case shows how effusion work because its not the concentration that makes the balls moving to the bottom part of the container. No ball moving from bottom container to top either.
