What were the names of the two atomic bombs made in los alamos

THE FIRST ATOMIC BOMBS: "Little Boy"and "Fat Man" There were actually two new bombs, one using uranium, the other plutonium, with different triggering devices for each. The main research and production sites were Los Alamos, New Mexico; Hanford, Washington; and Oak Ridge, Tennessee! :) please mark brainliest:)

Contributing factors  leading  to the harlem renaissance were the great migration of african americans to northern cities, which concentratedambitious  people in places where they could encourage each  other, and the first world war, which had created new industrial work opportunities for tens of thousands of people.
