A book sits completely still on a classroom desk. are the forces acting on the book balanced or unbalanced explain your answer

This is because the book is completely still, meaning it has no acceleration. According to Newton's First Law of Motion, an object at rest will remain at rest unless acted upon by an unbalanced force. Since the book is not moving, the net force acting on it must be zero, indicating that all forces are balanced. The downward force of gravity is perfectly counteracted by the upward normal force from the desk.
