it is because of Inertia,the tendancy to resist motion.
the coin will at rest because you slowly pull the cardboard
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 property of inertia kept the coin in place while the card was flicked from beneath it. The coin remained at rest due to its tendency to resist changes in its state of motion unless acted upon by an external force.

As you slowly pull the cardboard, the coin will gradually slide down the inclined plane due to gravity. The friction between the coin and the cardboard will also play a role in determining the speed at which the coin moves.
If you place a coin on top of the cardboard covering the beaker, it will not fall into the beaker due to gravity. The coin's weight is spread out evenly on the cardboard surface, preventing it from piercing through. However, it is always recommended to handle laboratory equipment carefully to prevent accidents.
As you slowly pull the cardboard, the friction between the cardboard and your hand creates a force in the opposite direction of the pull. This force resists the motion of the cardboard and causes it to move gradually. Additionally, the adhesive properties of any glue or tape on the cardboard may also affect the ease of pulling.
The coin would float.
nothing happens
