to reduce air resistance
sound wave reflect best off smooth, hard surfaces
Epithelial tissues are the smooth tissues that cover surfaces in the body. They serve as a protective barrier and are found in the skin, lining of organs, and throughout the body. Epithelial tissues are designed to absorb, secrete, and protect underlying structures.
Articular surfaces of bones are smooth bony projections that are designed to articulate with another bone, forming a joint. These surfaces are covered with cartilage to reduce friction and allow for smooth movement. Examples include the femoral head articulating with the acetabulum in the hip joint.
Smooth surfaces usually have less friction than rough surfaces because there are fewer irregularities and protrusions that can create resistance when two surfaces rub against each other. This causes objects to slide more easily on smooth surfaces compared to rough surfaces.
Yes, polyurethane can smooth out rough wood surfaces by providing a protective and smooth finish when applied correctly.
Because friction is less on smooth surfaces. Smoother the surfaces, lesser the friction.
Water droplets form on smooth surfaces due to condensation. When the smooth surface is cooler than the surrounding air, the water vapor in the air comes into contact with the surface and cools down, leading to the formation of liquid water droplets. This process is more likely to occur on smooth surfaces because they provide a uniform surface for the droplets to accumulate.

True.
Friction is least affected by smooth surfaces because there are fewer microscopic irregularities that can interlock and create resistance between the surfaces. This results in less friction compared to rough surfaces where more interlocking can occur, increasing the resistance.
Yes, smooth surfaces can still produce friction. Friction is caused by the resistance between two surfaces when they are in contact with each other, not only by the texture of the surfaces. Smooth surfaces can still generate friction, although the amount of friction may be lower compared to rough surfaces.
