What surface has the least amount of friction?
The surfaces used as the measure of lowest friction are generally wet ice on wet ice. Some materials, such as superfluid Helium III have no measurable friction.
Where is located the smooth ER in cell?
The smooth e.r. (endoplasmic reticulum) is located in the cytoplasm of eukaryotic cells. Like the rough e.r., the smooth e.r. is concerned with making proteins. Unlike the rough e.r., the smooth e.r has no ribosomes attached to it. Hope this helps. The whole article is on Wikipedia, in case this didn't help (see related link).
What surfaces create most friction?
a perfectly polished surface creates the most, follower by a rough surface, which is the more usual case.

What does 'co-efficient of friction' mean?
The amount of friction force that acts upon a body of mass depends on two factors: the property of the object and the normal force acting on the body. "Coefficient of friction" refers to the property of the material; in other words, the higher the coefficient of friction, larger the friction force is. The force of friction can be represented by this equation: FF = µFN. µ in this case represents the coefficient of friction. It can best be described as the numerical value that equates to the property of the object we are dealing with. µ does not have units; this reinforces the idea that it is just a numerical value that represents how "rough" or "smooth" the surface of an object is. Simply, the coefficient of friction is a way to describe, symbolically and numerically, how hard it is to move an object along a surface that the object is in contact with.
Are all igneous rocks rough?
Any igneous rock, if ground down to a smooth face and polished, will be smooth. Any igneous rock, if cut, will display a jagged edge. There is the potential for any igneous rock to be smooth or rough. A pumice may be an exception, but pumice isn't all igneous rocks. Most igneous rocks are not vesicular. Pumice will always be rough. Obsidian is naturally smooth, though not perfect. It has conchoidal fracture, so it may show a smooth face, but this is not always the case. Any rock that has been tossed in a river or on a beach for a few thousand years will be pretty smooth, no matter what it is (except pumice). A rock fresh from the quarry will nearly always be jagged and rough. Due to the crystalline texture of igneous rocks, most will naturally fracture in a way that leaves a rough face, if that is what you meant.
What are the factors that reduce in case of friction?
the factors that reduce in case of friction are the velocity and acceleration.
What are theAdvantage or disadvantage of friction?
The main disadvantage of friction is that energy is required to overcome friction and that energy is effectively wasted. On the other hand, friction enables motion. If there were no friction, it would be like an extreme case of trying to walk on ice or on a very smooth surface with an oil slick on it. You could not get any traction to start moving or, if already moving, it would be impossible to change the magnitude or direction of motion.
What is physical difference between surfaces with high and low coefficients of friction?
A high coefficient of friction may be caused by a rough surface. It may also be the result of surfaces sticking together, as in the case of rubber which tends to stick to certain surfaces, at least when it is dry. Lubrication - such as a thin layer of oil - tends to reduce the coefficient of friction.
What causes a transmision to slip?
I'll assume you mean an automatic. If so, there are friction plates inside the transmission that get worn out and just like old sand paper gets smooth and doesn't do it's job very well, the friction plates get smooth and don't grip anymore, causing the transmission to slip. In the possible case it is a standard transmission, it isn't the transmission, it's the clutch slipping.
What type of friction do you have to overcome to make a book move across a desk?
Static friction
How does friction affect perpetual motion?
When there is friction - as is usually the case - motion will eventually stop.
