What is low and high friction inside the house?
I assume you are looking for examples. Low friction: drawer-slides, door-hinges, water flowing through the pipes. High friction: carpet pile, some types of window catch so the casement stays where set.
What is rolling friction and sliding friction?
I assume this relates to a wheel. When the wheel is rolling, the surface of the wheel is not moving relative to the surface of the road when they are in contact. however, the wheel deforms slightly and because of this, the normal force slightly opposing the motion of the wheel rather than simply pushing it up. This is rolling friction or more commonly known as static friction. When the wheel is sliding, the wheel is sliding over the road's surface, meaning that there is relative movement between the wheel and the road. this is known as sliding friction or kinetic friction.
Why does friction on an inclined plane increase as the height of the inclined plane increases?
It doesnt. I assume you mean angle, and as the angle increases the frictional force creases as friction is dependant upon the force of the normal. When the angle increase's the force of the normal decreases (because it is a cosine function).
If two objects have the same mass can you assume they have the same volume Explain give example?
Two objects has got same mass means the mass of both the objects is same. It does not comment any thing about the volume of the objects. If the density of the two objects is same, then only their volume will be same. If both the objects are not made up of the same material, they have most likely to have different volume. Rarely it may be same.
What is the different between istatistic and kinetic friction?
I assume you mean static and kinetic friction. Static friction tends to be stronger and less predictable. For example, if you start applying more and more force to a stationary brick lying on sandpaper, it is almost impossible to predict when it will begin to move. Once it is moving, however, you can get a pretty consistent estimate for how much drag the brick is experiencing (kinetic friction). Modern cars have computers monitoring the brakes. If you slam on your brakes, the computer will loosen up the brakes to prevent you from skidding. This is because static friction is more effective than kinetic friction, and once you start skidding out you have lost most of your braking power.

What is the measurement of the pull of gravity between the earth and the earth objects?
I assume you mean "between Earth and other objects". That is called the WEIGHT of the objects.
How does rolling friction differ from sliding friction?
friction is a eorce of contact between two surfaces which opposes motion of objects over one another. In rolling friction the area in contact between two objects is comparatively less then that in case of sliding as in rolling, one object just roll over each other hence area of contact is less so force of rolling friction is less than sliding friction.
What is kinetic friction and static friction?
Friction is the resistance to movement of an object pressing/resting/moving on a surface. It's not intuitively obvious but the standing still friction and moving friction are different. Assume you have a block of wood resting on a tabletop. The amount of force required to make the block begin to move (static friction) is greater than the force required to keep it moving (kinetic friction) after it has begun to move.
Does sand affect melting points?
I assume you mean of ice. No. It only provides traction (more friction) on ice.
If an objects mass is 50g and its volume is 100 cm what is the objects denisty?
I assume you mean cm^3, in which case the density is 0.5g/cm^3.
What are some of the smallest science objects?
I assume you mean, scientifically, what are some of the smaller objects. Well, electrons of the atom are very minute objects, but if you want to go beyond that, you can look into neutrinos. They are literally "stardust", and billions of them collide with the earth each second, but because they are so small, they pass through earth's particles, making it hard to detect and examine.
Is coefficient of friction or coefficient of limiting friction are same?
Limiting friction is just the maximum static friction force (if you go over that point static friction becomes kinetic friction).Let f = frictional force,c = coefficient of frictionN = Normal forcefmax = cN = limiting frictionAlthough the term coefficient of limiting friction is not really used, I'd assume it would just be "c" (it's a coefficient after all). So they would be the same.If you meant is coefficient of friction the same as limiting friction, than the answer is no. Coefficient of friction is just the "c" in the equation. Limiting friction however is the product of the coefficient and the normal force.
Is it a birth defect if you can't snap?
By snap I assume you mean snapping your fingers, if that's the case, the answer is no, the sound generated from your fingers are caused by friction and when you fail to make a sound it just indicate that there is insufficient friction, thus it is just a technique that not perfected!

Is it a good choice to convert MS COM objects to stored procedure?
I assume you mean Microsoft StoredProcedure objects. If so, it would be a bad choice as SQL 2008 was the last version to support the feature.
