Answer:
Both technician A and technician B are correct.
Explanation:
Both technician A and technician B are correct.
Technician A is correct in stating that friction is a force that slows or prevents the motion of two moving objects or surfaces that are in contact with each other. Friction is a result of the resistance encountered when one object slides or tries to slide over another. It acts in the opposite direction to the motion and can slow down or stop the objects from moving. For example, the friction between the tires of a car and the road surface helps the car to stop or slow down when the brakes are applied.
Technician B is also correct in stating that friction occurs in liquids, solids, and gases. Friction is not limited to just solid objects. It can also occur in fluids like liquids and gases. In fluids, friction is often referred to as viscous drag or fluid resistance. When an object moves through a fluid medium, such as a swimmer moving through water or a plane moving through air, the fluid exerts a resistance force on the object that opposes its motion.
Therefore, both technician A and technician B are correct in their statements about friction.
