Density mass and volume
In optical density measurements, D typically stands for "Absorbance" and is commonly used as a unit of measurement to quantify the amount of light absorbed by a sample. The higher the D value, the more light is absorbed by the sample.
That depends what you want to measure: length, width, volume, weight, mass, density, etc.
A very common instrument for the direct measurement of the density of a liquid is the hydrometer, which measures the volume displaced by an object of known mass. A common laboratory device for measuring fluid density is apycnometer; a related device for measuring the absolute density of a solid is a gas pycnometer. Another instrument used to determine the density of a liquidor a gas is the digital density meter - based on the oscillating U-tube principle.
A micrometer, in relation to the density of plastics, is a unit of measurement used to quantify the thickness of plastic films or sheets. It measures the thickness of the plastic material in microns, which is one-thousandth of a millimeter. This measurement is crucial in determining the density and quality of plastic materials.
Pencil erasers are used to remove mistakes or change markings made with pencils on paper. They can also be used to create texture or shading in artwork. Additionally, pencil erasers can be used to clean small smudges or marks on surfaces like walls or electronic devices.

just pull out the used eraser and replace it with a new one
In the context of gold, "scc" typically refers to "specific gravity," which is a measurement of the density of a material compared to the density of water. This measurement is often used to assess the purity and authenticity of gold, as different alloys and impurities can affect the specific gravity of the metal.

used to make eraser
No, a frozen eraser would not get hot when used. In fact, it may feel even cooler than a regular eraser due to the low temperature.
To explain first: density is mass (m) per unit volume (V)-how heavy something is compared to its size. Water, for example, has a density of 1g/cm3.
The answer depends on the units used for the mass and volume. Without measurement units, the answer has no meaning.
The metal ring on a pencil, usually found at the end opposite the eraser, is called a ferrule. It is used to secure the eraser in place.
