The shelf must exert an upward force on the book that is exactly equal to
the book's weight. If the forces on the bottom of the book were not balanced
(did not add up to zero), then the bottom of the book would be accelerating.
The floor exerts an upward force of 200N on the woman, which is equal in magnitude to her weight to keep her stationary. This force is known as the normal force, which acts in the opposite direction to the force of gravity.
A bicycle seat exerts a force on a rider by supporting the rider's weight through normal force. When a person sits on the seat, their weight pushes down on the seat, and the seat pushes back up with an equal force (normal force) to support the rider.

To decrease the friction an object experiences, you can change the surface it sits on to a smoother material or reduce its weight. Decreasing the weight of the object can reduce the normal force acting on it, which in turn reduces the friction force.
The force that stops a box from falling through a table is the normal force. This force is exerted by the table in the upward direction and counteracts the downward force (weight) of the box, preventing it from falling through the table.
The floor exerts an upward force of 200N on the woman, which is equal in magnitude to her weight to keep her stationary. This force is known as the normal force, which acts in the opposite direction to the force of gravity.

Yes, a pile of soil sitting on the ground exerts force on the ground beneath it. The soil has mass, and gravity pulls it down on the whatever is under it. A red ant standing atop the pile of soil exerts an extra force on it, to continue the figure.

A book, no matter where it sits, is an organized and bound assembly of paper with information stored on it. The book has some mass, and like any mass, its gravitational potential energy relative to the floor can be defined in terms of its mass and its distance above the floor.
A bicycle seat exerts a force on a rider by supporting the rider's weight through normal force. When a person sits on the seat, their weight pushes down on the seat, and the seat pushes back up with an equal force (normal force) to support the rider.

I would not buy one that is over 6 months old. But the shelf life is at least a year. After the battery sits on the shelf for over 3 months it is a good idea to charge it before putting it into service.
How long a unit of inventory sits on a shelf before it is sold is a measure of time. The inventory turnover rate is a ratio that shows how many times the inventory is sold and replaced over a certain length of time.
