During normal expiration, the primary force responsible is the relaxation of the diaphragm and external intercostal muscles, leading to a decrease in thoracic volume. This increase in pressure within the lungs causes air to be pushed out. Additionally, elastic recoil of the lungs and chest wall helps to facilitate expiration by returning them to their resting position after inhalation.
The support force on an object is called the normal force because it is perpendicular (normal) to the surface on which the object rests. It acts in the opposite direction to the force of gravity to keep the object in equilibrium.
Normal expiration is brought on by the relaxation of the diaphragm and external intercostal muscles, causing the thoracic cavity to decrease in volume, which increases the pressure in the lungs. This increased pressure pushes air out of the lungs.
The normal force for an object on a flat surface is equal in magnitude and opposite in direction to the force of gravity acting on the object. It is responsible for balancing out the gravitational force to keep the object stationary or in equilibrium on the surface.
No, a frictionless surface cannot exert a normal force because the normal force is a force exerted perpendicular to the contact surface and is necessary to counteract the force of gravity or any other downward force. Without friction, there is no need for a normal force to counteract any horizontal force component.

Nothing. The relaxed state of the chest is fully exhaled. Breathing out, expiring, is normally accomplished by relaxing the diaphragm and the muscles of the ribs. No force is used. It is possible to exhale forcefully, but the question did not ask that.
The Horizontal Component of the normal force.

The force that is responsible for moving sediments in a river is the current.
No, a frictionless surface cannot exert a normal force because the normal force is a force exerted perpendicular to the contact surface and is necessary to counteract the force of gravity or any other downward force. Without friction, there is no need for a normal force to counteract any horizontal force component.
Other common names for the normal force that opposes gravity are support force, contact force, and reaction force.
As the angle of the incline increases, the normal force (support force) decreases. The normal force is perpendicular to the surface, and as the incline becomes steeper, more of the gravitational force acts parallel to the incline, reducing the normal force required to keep the block in equilibrium.
The normal gene is responsible for a muscle protein controlling the flow of sodium during muscle contraction.
