What is the difference between a line a shape?
a line is a basic line drawn from a pencil a shape is a shape for example a star is a shape
Is the number 1 symmetrical?
Only if it's drawn as a straight line. If the horizontal line at the base, and the sloping line at the top are added, it is not symmetrical.
What is used to help find the area of a parallelogram?
The formula for the area of a parallelogram is the same as for a rectangle. base x height Just remember that the height is a line drawn perpendicular to the base, not the other side length.
How long of a line can a pencil draw?
The regular pencil can go 35 miles long if you keep sharpening it. But if you don't it depends how good of quality your pencil is!
A straight line that is drawn from side to side is what type of line?
Horizontal
Will a line drawn by a pencil conduct electricity?
we know that graphite(pencil lead)conducts electricity.a line drawn by the pencil contains graphite particles.then why can't it conduct electricity?
What is the difference between a line a shape?
a line is a basic line drawn from a pencil a shape is a shape for example a star is a shape
How should a best-fit line be drawn?
There are clear mathematical procedures for calculating the slope and intercept of the "best-fit" line. Once those numbers are in hand, the line should then be drawn using a straight-edge and fine-point pen or sharpened pencil.
Is the number 1 symmetrical?
Only if it's drawn as a straight line. If the horizontal line at the base, and the sloping line at the top are added, it is not symmetrical.
Why is it important to use only a pencil to mark the starting line of the chromatogram?
This is so you can know the base line. The base line is used as the starting point for the mesaurements used for the Rf values. you need to know the distance from the base line to the point of the spot to know the Rf values. see related link below for more info about paper chromatography
Where is the commitment line in slow pitch softball?
The commitment line is drawn perpendicular to the third base line 20 feet from the point of home plate.
Why should a pencil never be used as a tool when working inside a computer?
Because pencil has graphite lead, which is a good conductor of electricity. Hence to avoid the shock pencils are avoided.
Does pencil fade on paper?
yes pencil fades on paper overtime especially pencil drawings this is due to the friction caused when paper rubs off against each other even when flipping pages and with moisture one day you will have a dark line drawn of pencil then later the line becomes lighter and lighter until you can easily erase them. On a science level i think its because the paper molecules are breaking down constantly
How do you get the area of a parallelagram?
A = bh, where b is the length of the base (which can be any side of the parallelogram, and h is the length of the height (a perpendicular line drawn from one of the vertex to the base).
Is a pencil a line?
No it is not.
Why does the baseline need to be drawn in pencil?
A datum line mustn't be drawn in ink so that when you add the solvent while doing chromotography, the ink doesn't spread and it might even mix with the actual color that you are testing on and that could change the r f value whereas if you draw it with a pencil, the results would be more accurate. Hope that helps :)!
Is lead hard?
The "lead" in drawing pencils has various grades or hardness. The hardness of a drawing pencil is designated by a number and an H. The higher the number the harder the pencil is, the slower it wears done, the longer it retains its point, the less it smudges and the lighter the line is that is drawn. For example, 6H pencils are harder than 2H pencils. The softness of a pencil is designated by a number and a B. The higher the number the softer the pencil is, the faster it wears down, the easier it is to smudge and blend, and the darker the line is that is drawn. For example 8B pencils are softer than 2B pencils. There is a standard, middle of the road pencil, the HB pencil, sometimes called the Number two pencil. This has some of the drawing qualities of both hard and soft pencils and in a pinch will serve for most drawing and writing needs.
