Question

what is Dimension?

define the process of diffusion with example?​

Answer 1

Answer:

In geometry, the circumference is the perimeter of a circle or ellipse. That is, the circumference would be the arc length of the circle, as if it were opened up and straightened out to a line segment. More generally, the perimeter is the curve length around any closed figure.

In physics and mathematics, the dimension of a mathematical space is informally defined as the minimum number of coordinates needed to specify any point within it. Thus a line has a dimension of one because only one coordinate is needed to specify a point on it – for example, the point at 5 on a number line.

Answer 2

Explanation:

A dimension is a measurement such as length, width, or height. If you talk about the dimensions of an object or place, you are referring to its size and proportions.

Diffusion is the net movement of molecules from an area where they are at a higher concentration to areas where they are at a lower concentration. ... The difference in the concentration of a substance between two areas is called the concentration gradient .
