Question

determining the appropriate physical property

use the drop-down menus to complete the statements.

bianca is building a lightning rod to safely conduct lightning strikes away from a building. she should choose a material with high dropdown.

tess is manufacturing rolls of wire for hanging pictures. she needs a material that is dropdown so that it can easily be pulled into wire without breaking.

Explanation:

Analyze the first statement

The first statement describes Bianca building a lightning rod to safely conduct lightning strikes away from a building. A lightning rod must allow electrical current to flow through it easily to ground the strike safely. Therefore, the material needs to have high electrical conductivity.

Analyze the second statement

The second statement describes Tess manufacturing rolls of wire for hanging pictures. She needs a material that can easily be pulled into wire without breaking. The physical property that describes a material's ability to be stretched or drawn into a thin wire without fracturing is ductile (or ductility).

Answer:
