Final answer:
Technological innovations such as improvements in telecommunications, advancements in telephone systems, and inventions in nanotechnology and space exploration have reduced the frictional effect of distance travel.
Step-by-step explanation:
Three kinds of technological innovations that have helped to reduce the "frictional effect" of distance travel are:
- Improvements in telecommunications: Telecommunications have made it easier and cheaper to manage long-distance economic connections of production and sales. Products and services that can be transported over telephones and computer networks at ever-lower costs include computer software, financial advice, travel planning, music, books, movies, and blueprints for designing a building.
- Technological advancements in telephone systems: Innovations like microwave transmission, communications satellites, and other wireless technologies have improved phone call quality and reduced the cost of long-distance calls, making communication more efficient and affordable.
- Inventions in nanotechnology, miniaturization, and space exploration: These advancements have revolutionized the computer industry, allowing for smaller and more portable devices that facilitate worldwide communication. Additionally, space exploration has led to the development of satellites that deliver the internet, track weather, and map changes on Earth.
