BRAINLIEST TO THE FIRST PERSON PLS HELP This excerpt, from an imagined account based on the actual events of August 6, 1945, describes the immediate effects upon one family which weapon was first used? What incident provoked the use of this new weapon?

“. . . Everything flashed whiter than any white she had ever seen. . . . the reflex of a mother set her in motion toward her children. She had taken a single step (the house was 1,350 yards, or three-quarters of a mile, from the center of the explosion) when something picked her up and she seemed to fly into the next room over the raised sleeping platform, pursued by parts of her house.
“Timbers fell around her as she landed, and a shower of tiles pummeled her; everything became dark, for she was buried. The debris did not cover her deeply. She rose up and freed herself. She heard a child cry, "Mother, help me!," and saw her youngest—Myeko, the five-year-old—buried up to her breast and unable to move. As Mrs. Nakamura started frantically to claw her way toward the baby, she could see or hear nothing of her other children. . . .”
–John Hersey, 1946
