A Canadian inventor named Reginald Fessenden invented SONAR in the early 20th century.
It originated from the early 20th century. It was named after Gaspard Coriolis (1792-1843), a French engineer.
Physicists as early as Michael Faraday (1791-1867) invented simple motors based on the principle that magnetic fields could be created, manipulated, and turned into mechanical motion. Without it, technology wouldn't exist. Although he didn't 'discover' it, he was the first to produce it.

Radio was not an important invention in the early 20th century. Instead it was developed by Heinrich Hertz in the 18th century. The cotton gin (APEX)
It was so fast and revolutionary for its time. During the early 19th century, this was an exciting innovation.
England, in the early 1800s.
That was the "Iron Horse".
The early invention improved the transcontinental transportation of the people and goods was the steam locomotive. This was facilitated by the rail road network that was developed.
Depends on the type of engine that the train is equipped with. Steam, diesel, electricity, (supplied by overhead wires or additional rails,) batteries, gas turbine. (Steam was the dominant form of locomotive power from the early 19th century to the mid 20th century). Your question is somewhat uncustomary. It should be asked this way : How does the different types of engine in a train produce power? It is unnecessary to provide detailed explanations on how the different kinds of engine work. That's a technical information which is not interesting for the inquisitor.
In the late 19th and early 20th century oil was distilled to produce kerosene for lanterns and the byproducts was gasoline
