Question

anton created a chart listing different types of materials. which best complete the chart? types of materials conductor: silver insulator: x semiconductor: y superconductor: mercury x: copper y: glass x: rubber y: copper x: paper y: silicon x: silicon y: glass

Explanation:

• Conductors (e.g., silver, copper) allow easy electricity flow.
• Insulators (e.g., glass, rubber, paper) block electricity.
• Semiconductors (e.g., silicon) have moderate conductivity.
• Superconductors (e.g., mercury) have zero resistance at low temps.

Check options:

• X (insulator) needs an insulator; Y (semiconductor) needs a semiconductor.
• Option 3: X=paper (insulator), Y=silicon (semiconductor) fits.

Answer:

X: paper, Y: silicon
