Two key substances needed for conduction are electrons and a conductive material. Electrons serve as the charge carriers that move through the material, while the conductive material provides a pathway for the electrons to flow.
The most important property is the conductivity of the material under consideration. A high conductivity is needed for the inside, and a very low conductivity for the outside. Only after this can we consider other factors, such as cost, strength, toxicity, flammability, flexibility, corrosion resistance and ease of making and shaping.
There is no material that is completely impervious to the destructive force of dynamite or TNT. While certain materials may offer resistance or be more resilient to the explosive impact, the level of destruction ultimately depends on the quantity and placement of the explosive in relation to the material.
Metal wires are single strands of flexible material often used to carry electrical currents, telecommunication signals, and hold mechanical loads.
Rubbing lead pencil on a key leaves a layer of graphite on its surface, which acts as a lubricant. This reduces friction between the key and the lock mechanism, making it easier to turn the key.

the key or legend
No, opaque refers to a material or surface that does not allow light to pass through it. It can be a solid color or have patterns, but the key characteristic is that it is not transparent.

A field that uniquely identifies a particular record in a table is called a primary key. The field or fields on which records are sorted is called the sort key.
The field that uniquely identifies a record in a table is called the primary key. It ensures that each record in a table is distinct and can be easily located and referenced.
attribute of an entity which uniquely identifies a specific instance of the data
It is called the "key".
High vapor pressure
Color of the material is not important when selecting a material for a light bulb filament. The key properties to consider are electrical conductivity, melting point, and heat resistance.
In a database, a field that uniquely identifies a particular record in a table is called
