Question

The term “atomic age” was first coined in the 1950s because of which of the following factors?

feelings of optimism toward nuclear energy in the years after World War II
fear in response to the threat of nuclear warfare that was prevalent throughout the Cold War
relief stemming from the belief that the atomic bombs in World War II saved American lives
anger in response to the use of the atomic bombs against Japan at the end of World War II

Answer 1

"feelings of optimism toward nuclear energy in the years after World War II"

Step-by-step explanation:

The atomic age (also known as the nuclear age) was an expression used for a time in the 1950s, in which it was believed that the energy sources of the future would be nuclear. The atomic bomb would make all conventional explosives redundant and nuclear power plants would do the same with fossil energy sources, such as coal or oil. There was a general feeling that everything would use nuclear power of some kind.

Answer 2

your answer will be "fear in response to the threat of nuclear warfare that was prevalent throughout the Cold War". 1950 was a year that was within the cold war, and the fear of an out all war with the Soviet Union was lurking, and so the "atomic age" was coined.

it is also coined for the usage of the 'making of the nuclear energy' however it is usually referred to the cold war.

hope this helps
