A person plugs a power cord into an electrical outlet in the wall. The power cord is covered in black rubber. Which statement is an accurate description of the materials?(1 point) Electrons move through air when the cord is a few inches from the outlet.

Electrons would easily move through the person if there was no rubber around the wire.

Electrons would not move through the wire if there was no rubber around the wire.

Electrons easily move through the rubber around the wire.

Electrons would easily move through the person if there was no rubber around the wire.

Explanation:

The black rubber material is an insulator and will not allow the conduction of heat or electrical current through it. Electrical currents are generated by the movement of electrons through materials.

Hence, if there was no rubber covering around the power cord, the person that plugged-in the power cord would have experienced electric shock because electrons would easily move through him/her from the wire.

i think that is the right

the density of gold = 19.3 g/cm3

the relation between density and mass and volume is

density = mass / volume

given :

mass of gold = 13 g

density = 13g / volume = 19.3

volume = 13 /19.3 = 0.67 cm^3

thus volume of gold nugget = 0.67 cm^3
