Name two innovations or inventions that came about during World War II. Explain why such innovations occur during a time of war.

radar, jet propulsion, and atomic power. idk how to explain them

Explanation:

Jerrycans

Jerrycans were needed to put out fires caused by bombs with efficiency and much more ease than before. They were also portable which made them a great tool for both sides of the war, especially as air bombing was becoming much more common and used much more frequently.

Penicillin

Penicillin was known as a ‘miracle drug’ in war, and saved a countless number of soldiers both from the Axis and Allied forces. Penicillin would treat certain infections caused by bacteria that could spread rapidly when the victim was in harsh conditions – which most soldiers out at war were experiencing (harsh conditions and environments).
