Question

Resistance of a material being scratched in known as _____. brittleness density hardness softness

Answer 1

Correct answer choice is :

C) Hardness

Step-by-step explanation:

The electrical resistivity of a material is also recognized as its particular electrical resistance. It is a measure of how firmly a material reverses the flow of electric current. A determination of resistivity is the electrical impedance per unit length and per unit of cross-sectional area.

Answer 2

I think the correct answer from the choices listed above is the third option. Resistance of a material being scratched in known as hardness. It is defined as the ability of a material to resist plastic deformation. Hope this answers the question. Have a nice day.
