What is 1 dimensional?

Answer 1

---"FLAT" !!!

Answer 2

One Dimensional

Answer 3

1 dimensional

Answer 4

Anything between 0 and 2 dimensional as in a line.

Answer 5

For line we just needed 1 coordinate to specify it. Physically it does not exists if we says that line have some width (even seen with microscope) then in this sense single dot (.) is also three dimensional but we cannot locate in 3-D coordinate system so it is zero dimensional likewise line is 1 dimensional.

Answer 6

To measure the length of a line we can just use a ruler.

It is expressed as 10 inches or 12 metres.

To measure the area of a rectangle we have to measure the length and breadth using ruler and the length and breadth should be multiplied. It will be expressed in square units.

Let the length be 10 inches,breadth be 12 inches, hence the area will be equal to 10 x 12 = 120 square inches.

Again to measure the volume of a rectangular slab we have to measure the length, breadth and the height and all the three should be multiplied. It is expressed in cubic units.

Let the length be 2 inches, breadth 3 inches, height 5 inches. Hence the volume will be equal to 2 x 3 x 5 = 30 cubic inches.

In these above three examples ,

In length only ONE quantity is used and it is ONE DIMENSIONAL.

In calculating the area TWO quantities are multiplied and hence it is TWO DIMENSIONAL

To find the volume, THREE quantities are multiplied and it is called THREE DIMENSIONAL

A line is very difficult to draw. It is humanly impossible. A line means "a length without a breadth". But when we draw a line with the sharpest instrument and view through a microscope definitely we can see a breadth. That means it is an area with length and breadth. So to draw a line is practically imposible.

Answer 7

1 dimensional is a mathematical concept, and as such a "line" as people above have argued has width and length under a microscope, is not what we are considering here. Math has to do with space and ideas, so the line that is said to be 1 dimensional (that is what the first dimension would be--a line) does not have to physically exist, nor does a point. physically, if you DRAW a line or point on paper, yes, it will be two dimensional. anything on paper is two dimensional, because it is in the physical form on a flat surface. The first demension, in reality, is invisible, though it exists for our use in grasping mathematical concepts. As such, I have to add, a "3-D" drawing, on paper, is the as 3 demensional as a "1-D" drawing on paper is 1 demensional. With that analogy in place, perhaps the idea can make more sense. Three-D on paper, is in reality two-demensional, but appears three-D because it has the length, width, and height drawn in, and as such so can a 1 demensional drawing (a line) be in appearance "one-demesional" until further scrutinized with scientific tools like a microscope. i may have milked my point, but hopefully i have made clear the difference between the "line" as it is described above and the mathematical concept of a line.

Answer 8

Any line is 1-dimensional technically, but the above answerer is right - even the finest line has at least length and width, making it at least 2-dimensional. If you want to see this, draw a line with a very fine pen or pencil and view it under a microscope.

A dot, however, technically does not have any dimensions and is called 0-dimensional. Yet the microscope trick would prove differently as well.

Answer 9

The above answers mentioning points and lines as 0 and 1 dimensional figures are correct, and are speaking of the hypothetical / mathematical figures. You couldn't draw them, because any line/dot you put on paper would have 3 dimensions, no matter how tiny they may be. (the ink trail has thickness too, hence 3d). But theoretically, a true "point" has no dimensions, and a true line has only length, as stated previously.

I am responding just in case you're looking for another possible answer: a function is 1-dimensional if it only contains one variable. (e.g. f(x) = 14x^2 + 5x) The function is defined for one variable: X. 16 = x^2 + y^2 is a two-dimensional equation (defining, in this case, a circle, radius 4) using X and Y as the two dimensions.

16 = x^2 + y^2 + z^2 is a 3d function describing a sphere, etc.

Answer 10

one dimensional is a thing that can only be meassured once as in length and an example is clearly a line as the people stated before and for all i know to this point is the only 1 dimensional figure i should say

Answer 11

"1 dimensional" means something has a length, but no width or height. It would be a line. I don't mean a line like copper wire. wire has thickness. A 1-dimensional object has no thickness at all, only length. It would be completely invisible, have no surface area, have no mass, and would be undetectable by any scientific instrument. Basically, it would not interact with our universe at all.
