What is a perfectly symmetrical that has no edges or vertices and not a polyherdron all points on the surface are equal surface from the center?
Sphere
Calculation of contact angle?
Angle of contact is the angle between a tangent to the liquid surface at the interface and the solid surface inside the liquid. For concave surfaces, it is acute . For convex surface , it is obtuse.
Is the moon a perfect circle?
No , not with the surface being with so many craters .
How do you figure the surface area of a dome?
A perfect dome (1/2 of a sphere) has a surface area of 2piR2. This is because a sphere's surface area is 4piR2, and dividing that by 2 would simplify to 2piR2.
What covers approximately what percentage of earths surface 25 45 60 or 70?
70
Do most satellites in the outer solar system have perfect smooth surfaces?
No. No object in the solar system has a perfectly smooth surface. These satellites have craters, mountains, and valleys.
Why is it that when central placeses colonize an isotropic surface a perfectly hexagonal regular pattern of distribution is the result?
An isotropic surface is the optimal environment for central colonization, therefore creating a perfect distribution of regular hexagonal patterns.
Explain what is meant by a food contact surface?
Surface that touch food are called "food contact surfaces".
Why it is easy to roll a cylindrical eraser on a paper sheet than to slide it?
because the area of contact of eraser in rolling is less than the area of contact of eraser in sliding
In woodworking why is this called a planer?
A 'plane' is a perfectly flat surface defined mathematically by three points. A planer is designed to create a perfectly flat surface on wood.
Does the frictional force depend on the area of surface contact?
No. Frictional force is independant of surface area.
Food contact surface definition?
A food contact surface is any surface of equipment, utensil, containers and wrappings that come into direct contact with food.
Does a smaller rock a have higher or lower percentage of surface area than a larger rock?
It depends on percentage related to WHAT! You cannot express surface area as a percentage of volume since the dimensions are different. So the only percentage you can have is the suface area of the smaller rock as a percentage of the surface area of the larger rock. In that case, the answer, not surprisingly, is that the smaller rock has the smaller percentage surface area.It depends on percentage related to WHAT!

What is the effect on coefficient of static friction when side length of a cube of 5 cm is doubled to original?
The surface areas in contact do not affect the coefficient.The surface areas in contact do not affect the coefficient.The surface areas in contact do not affect the coefficient.The surface areas in contact do not affect the coefficient.

Would it be say that no force acts on a body moving on a perfectly smooth surface?
It would not be a perfect answer if I said yes because you did not assume that if the body was moving in vacumn. If its not, like for example it is moving on an ice block on the surface of the earth then the object still has gravity and the air friction acting on it. Even the molecules of the ice's surface attract the surface of that object it is in contact with. So if I say that the object is in space then it would be a incredibly correct answer to say yes, there are no force acting on the body.
What are Surfaces that touch food are called?
