What kind of solutions don't conduct electricity?
One solution that will not conduct electricity is pure water. The reason is that it needs a dissociated ionic compound that can mix with water when detached, and then it will be unable to conduct.
Is it really possible for a human to draw a line with a pencil?
Yes, it is possible for a human to draw a line with a pencil. A line is a fundamental element in drawing, and with practice and fine motor skills, individuals can create straight or curved lines using a pencil.
Why one person do not get shock while touching a tree which is touching the transmission line?
that's because trees are made up of wood which does'nt conduct (transmit) electricity
Why shouldn't you use metals to conduct static electricity?
Metals are perfectly fine if all you want is to discharge the static electricity, but they conduct so well that the discharge often results in a very high current spark.To reduce the possibility of such sparks (which can trigger explosions, damage electronics, etc.) it is better to use high resistance dissipative materials (e.g. treated plastics, humidifiers, air ionizers, in-line megohm resistors on wriststraps, etc.) to slowly discharge the static electricity.
What are metals in the periodic table classified as?
In the periodic table, you can see a stair-stepped line starting at Boron (B), atomic number 5, and going all the way down to Polonium (Po), atomic number 84. Except for Germanium (Ge) and Antimony (Sb), all the elements to the left of that line can be classified as metals.
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.
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
Why is the chromatograph line dawn in pencil and not ink?
The chromatograph line is drawn in pencil because pencil marks are more permanent and less likely to smudge when in contact with the organic solvents used in chromatography. Ink can dissolve or spread when exposed to these solvents, affecting the accuracy of the chromatogram.
How can something conduct electricity?
Items conduct electricity by lining up their atoms. much like how things get magnetized. if the atoms line up then electricity can pass between them using them like a bridge. some items, however, cannot line their atoms up (like wood)
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.
What is the material in a pencil?
The material in a pencil is typically graphite, a form of carbon that leaves a mark when drawn on paper. The graphite is mixed with clay to create the pencil "lead" that is encased in the wooden barrel of the pencil. The hardness of the lead can vary, producing different shades and line thicknesses.
What kind of solutions don't conduct electricity?
One solution that will not conduct electricity is pure water. The reason is that it needs a dissociated ionic compound that can mix with water when detached, and then it will be unable to conduct.
Is a pencil a line?
No it is not.
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.
What is a pencil line?
A pencil line is a mark made by a pencil when it is pressed against a surface, leaving behind a trail of graphite. It is usually used for drawing or writing.
What is a faintly drawn line?
A faintly drawn line refers to a line that is not clearly visible or is lightly marked, often created with a soft pencil or light ink. It lacks boldness and definition, making it less prominent compared to darker or thicker lines. Such lines may serve as guidelines or preliminary sketches in drawing and drafting, allowing for adjustments before finalizing the artwork or design.
Example of an straight line in real life?
The piece of lead in a pencil or the pencil.
