Nano Quiz Lesson 3

Explanation
Nano-Technology deals with anything that is between 1 and 100 nanometers. This range is considered significant in Nano-Technology because it is at this scale that materials and structures exhibit unique properties and behaviors. At the nanoscale, materials can have different chemical, physical, and biological properties compared to their bulk counterparts. This allows for the development of new materials, devices, and applications in various fields such as electronics, medicine, energy, and materials science.

Explanation
Moore's law is a well-known prediction made by Gordon Moore, co-founder of Intel, stating that the number of transistors on a microchip would double approximately every two years. This prediction has held true for several decades and has been a driving force behind the rapid advancement of technology. Therefore, the statement that Moore's law predicts the doubling of transistors every two years is indeed true.

Explanation
A transistor in a modern computer is an example of nanotechnology because transistors are made using nanoscale materials and processes. Nanotechnology involves manipulating matter at the nanoscale level, typically between 1 and 100 nanometers. Transistors in modern computers are typically made using semiconductor materials such as silicon, which are manipulated at the nanoscale to create the necessary structures and properties for the transistor to function. Therefore, the statement that a transistor in a modern computer is not an example of nanotechnology is incorrect.

Explanation
If you could stretch out all the copper wire in a modern computer chip, it would be over 2 miles long. This is because computer chips contain a complex network of copper wires that connect various components and facilitate the flow of electrical signals. The compact design of computer chips allows for a large number of wires to be packed into a small space, resulting in a significant length when stretched out.

Explanation
Nanotubes are stronger than plastic, steel, and aluminum. Nanotubes are cylindrical structures made of carbon atoms, which are arranged in a unique way that gives them exceptional strength. They have a high tensile strength, meaning they can withstand large amounts of pulling force without breaking. This property makes them stronger than traditional materials like plastic, steel, and aluminum, which have lower tensile strengths. Therefore, the correct answer is "all of the above" because nanotubes are stronger than all of these materials.

Explanation
The statement suggests that we are currently living in the Nano-Age. This implies that nanotechnology, which involves manipulating matter at the atomic and molecular scale, has become increasingly prevalent in our society. The term "Nano-Age" highlights the significant impact of nanotechnology on various fields such as medicine, electronics, and materials science. Therefore, the correct answer is True.
