When the cardboard is at rest, it is not undergoing any motion or change in position. It is stationary and its position remains constant.
If light strikes cardboard, the cardboard will absorb some of the light and reflect the rest. The color and thickness of the cardboard will affect how much light is absorbed or reflected.
answer
When the cardboard is at rest, the magnitudes of the two forces acting on it (gravity pulling down and normal force pushing up) are equal in magnitude and opposite in direction to maintain equilibrium. This means the net force acting on the cardboard is zero.
When the cardboard is pulled away quickly, the coin remains in place due to inertia. The coin tends to stay at rest until a force is applied to move it.
According to Newton's Law of Inertia, the coin on the cardboard would tend to stay at rest when the cardboard is pulled slowly due to its inertia. As you pull the cardboard, the coin will initially stay in place relative to the glass of water due to its inertia. However, when the force increases or the cardboard is pulled quickly, the coin will slide off the cardboard due to the force exerted on it.
When I slowly pulled the cardboard, the coin placed on top of the cardboard remained at rest but was dragged along with cardboard. Explanation: That is because, the coin was dragged by the force in the surface of the cardboard called friction.
the coin will at rest because you slowly pull the cardboard

Since the cardboard is at rest we know that it is not experiencing any acceleration, hence, the net forces acting on it add up to zero (in magnitude and direction). Force equals mass times acceleration.
