What to factors influence the amount of firiction when is friction the strongest?
The amount of friction is influenced by the nature of the surfaces in contact (smooth or rough), the force pressing the surfaces together, and any lubrication present. Friction is strongest when the surfaces are rough or irregular, creating more resistance to sliding past each other.
What determines how much friction occurs in a situation?
The amount of friction in a situation is determined by the nature of the surfaces in contact, the force pressing the surfaces together, and any presence of lubricants or contaminants. Smooth surfaces and lower pressure decrease friction, while rough surfaces and higher pressure increase it. Lubricants reduce friction by creating a protective layer between surfaces.
Why is it important for the mirrors to have smooth surfaces?
Mirrors need to have smooth surfaces to reflect light efficiently and accurately. Any imperfections or roughness on the surface can cause light to scatter or be distorted, resulting in a blurry or distorted reflection. Smooth surfaces help produce clear and sharp images.
What surfaces are better absorbers and emitters of thermal radiation?
Surfaces with dark, rough, and matte finishes are generally better absorbers and emitters of thermal radiation compared to surfaces with light, smooth, and shiny finishes. This is because dark, rough, and matte surfaces have higher emissivity values, which means they absorb and emit thermal radiation more efficiently.
Which factors determines the strength of the fristional force between two surfaces?
The strength of the frictional force between two surfaces is determined by the nature of the surfaces (smooth, rough), the normal force pushing the surfaces together, and the coefficient of friction between the two surfaces. Additionally, factors like surface area and the presence of any lubricants can also impact the frictional force.
On what surfaces can you successfully strike a match?
You can successfully strike a match on rough surfaces like sandpaper, matchbox striker, or any surface with friction. Smooth surfaces like glass or metal may not work well.

Why are image reflected from a rough surface not as clear as those reflected from a smooth surface?
Some light that falls on any surface is scattered back (reflected). A rough surface tends to scatter the light in different directions while a smooth surface tends to scatter more of the original (incident) rays straight back. This explains why a smooth surface reflects a "clearer" image than that reflected from a rough surface.
What are the best methods for smoothing out rough concrete surfaces?
The best methods for smoothing out rough concrete surfaces include using a concrete grinder or sander, applying a concrete resurfacer or overlay, and using a concrete patching compound to fill in any cracks or holes. These methods can help achieve a smooth and even finish on the concrete surface.

What surfaces does crazy glue work best on?
any surfaces really! just not rough stuff like sandpaper!

Which smooth surfaces reflect light?
Any smooth surface will reflect light. The better question is "How much light does each kind of smooth surface reflect?"
Is the rough endoplasmic reticulum covered with ribosomes?
No, the name Rough Endoplasmic Reticulum comes from the 'rough' appearance when seen under an electron microscope. The 'rough' bits are ribosomes which stud the surface. Smooth Endoplasmic Reticulum has no 'rough' bits ie. no ribosomes.

What surfaces will glue with Super Glue?
Any smooth, hard surface can be glued by Super Glue.
