Why was steel important to the second industrial revolution?

Steel was important to the second industrial revolution majorly because of its properties and its potential uses. Because steel is very strong, light and cheap, it was found ideal for many purposes. Steel was used to make many of the new inventions that characterized that period, a good example of this is rail road.

The answer would be false.

The business cycle is the periodic but irregular up-and-down movement in economic activity, measured by fluctuations in real gross domestic product (gdp) and other macroeconomic variables. a business cycle is typically characterized by four phases—recession, recovery, growth, and decline—that repeat themselves over time. economists note, however, that complete business cycles vary in length. the duration of business cycles can be anywhere from about two to twelve years, with most cycles averaging six years in length. some business analysts use the business cycle model and terminology to study and explain fluctuations in business inventory and other individual elements of corporate operations. but the term "business cycle" is still primarily associated with larger (industry-wide, regional, national, or even international) business trends.
