How do fiber optic cables transmit information, making them advantageous over traditional copper wires?

They vibrate at high frequencies to transmit data acoustically.

They transmit data as signals of light, allowing for higher speed and capacity

They use magnetic pulses, which are not affected by electrical interference.

They use superconductive materials to send electrical signals with zero loss.

None

What property of the synthetic polymer Perspex (Polymethyl methacrylate) makes it suitable for use in aircraft windows and car lights?

It is a good electrical conductor.

It is lightweight, strong, and transparent.

It is soft and highly elastic

It is opaque and absorbs all light.

None

Carbon nanotubes are utilized in advanced water filters. What function do they perform in this application?

They act as a membrane to physically block microorganisms and heavy metals.

They chemically neutralize all contaminants in the water.

They add beneficial carbon minerals to the water.

They increase the water pressure to speed up the filtration process

None

Styrene-butadiene rubber is used to make vehicle tires. Based on its name and the provided text, what type of material is it?

A natural polymer

A copolymer

A superconductor

A ceramic composite

None

The text identifies a major environmental issue with the disposal of advanced materials in electronic products. What is a primary reason that electronic waste (e-waste) is so harmful?

It is often disposed of through open burning, which releases toxic gases.

It is highly radioactive and requires specialized containment.

It biodegrades too quickly, releasing nutrients that upset ecosystems.

It absorbs a large amount of water, leading to soil dehydration.

None

Fiberglass is a composite material valued for being strong, lightweight, and corrosion-resistant. What are its two primary components?

Glass fibers and polyester resin (a type of plastic)

Carbon atoms and polymer chains

Silver chloride and regular glass

Steel rods and concrete

None

Nylon, commonly used for ropes, carpets, and clothing, is a synthetic copolymer. What does this imply about its monomer composition?

It is formed from two different types of monomers, hexanedioic acid and hexamethylene diamine.

It is made from repeating units of the natural monomer isoprene.

It is a modified version of the natural polymer, protein.

It is made from a single, complex monomer called ‘nylonene’

None

Photochromic glass, which darkens in sunlight, is created by adding which substances to regular glass?

Styrene and butadiene monomers

Polyester resin and glass fibers

Yttrium barium copper oxide

Silver chloride (or silver bromide) and copper(II) chloride

None

What is the defining characteristic of a superconductor when it is cooled below its critical temperature?

It develops extremely high electrical resistance.

It becomes a perfect insulator.

It exhibits zero electrical resistance

It converts electrical energy into heat energy with 100% efficiency.

None
