Metal and _____________________ are considered conductors.
a
rubber
b
silk
c
air
d
water
d) water
Metal and water are considered conductors.
The correct answer is "a" metal. Metal is a good conductor of electricity because it has a high number of free electrons that are able to move easily and carry electric current.
To find the answer to this question, you would need to know the properties of different materials when it comes to conducting electricity. Conductors are materials that allow electric charges to flow through them easily. On the other hand, insulators are materials that impede the flow of electric charges.
In this case, metal is a well-known conductor, as it allows electric charges to flow through easily. Conversely, rubber, silk, air, and water are not good conductors. Rubber and silk are examples of insulators, while air and water have some conductivity but are generally considered poor conductors when compared to metals.
