Each of those lines represents 1 centimetre, with the number tell you how man centimetres between that line and the first line (either unlabelled, or labelled 0).
Between those line there may be 10 little lines with the fifth one longer than the rest, but shorter than the labelled lines. These are millimetres, which are also 0.1 cm each.
The shorter lines represent one millimeter (mm). The longer lines with numbers next to them represent one centimeter (cm) (10 millmeters) High precision calculation for life or science: keisan dot casio dot com
you draw straight lines with a ruler
Ruler/Walking ruler thingy
The easy way to find the length of a pencil is to use a ruler to measure it. A "small" ruler might not make it, but a "regular" one foot ruler will do the job nicely.
using a ruler, draw any two lines that cross each other
why are the division lines on a ruler diffrent lengths

A length of two units!
On a typical inch ruler the smallest lines are 1/16th dimensions. The next biggest are 1/8th", then 1/4", and finally 1/2".
It measures length, and it also helps you draw straight lines
A ruler can be used to represent light rays because light travels in straight lines. By drawing lines with a ruler to show the path of light rays, we can visualize how they interact with different surfaces or mediums. This can help us understand concepts such as reflection, refraction, and dispersion of light.
something like texture, color, smell, sound and taste
The question is somewhat vague, but I think you may be asking: Why are different lines of latitude marked with different numbers ? I'd compare that to the question: Why are different marks on the ruler marked with different numbers ? The reason is because both of them are systems invented to help you measure things. The marks on the ruler help you estimate the length of things that you place the ruler on, by showing you where a few exact lengths are. And the horizontal lines on a map or globe help you estimate the latitude of places on the Earth, by showing you where a few exact latitudes are.
there should be the cm lines- the long ones with the numbers underneath. Inbetween these should be a series of shorter lines indicating the millimetres.
The two types of rulers are "ruler" used for measuring length or drawing straight lines, and "ruler" referring to a monarch or a person in authority.
Because light rays travel in straight line just like a ruler/scale. We can represent it with anything which is straight like a ruler...
The lines between centimeters on a ruler or measuring tape represent millimeters, which are smaller units of measurement than centimeters. There are 10 millimeters in one centimeter.
