Question

1. the principle of mass - energy equivalency, represented by the equation $e = mc^2$, explains how mass can be converted into energy. this concept is fundamental to nuclear reactions, which release large amounts of energy through changes in atomic nuclei. one such reaction involves splitting a large atomic nucleus into smaller nuclei, while another involves combining smaller nuclei to form a larger nucleus.

the principle of mass - energy equivalency is fundamental to nuclear reactions such as - choose the correct answer - (splitting a large nucleus) and - choose the correct answer - (combining smaller nuclei).

options for the first choose the correct answer: electromagnetic decay, gravitational collapse, nuclear fusion, nuclear fission

options for the second choose the correct answer: (combining smaller nuclei) (the options are not fully shown in the ocr but the context is about nuclear reactions)

clear all

Explanation:

For the first blank (splitting a large nucleus), nuclear fission is the process of splitting a large atomic nucleus into smaller nuclei. For the second blank (combining smaller nuclei), nuclear fusion is the process of combining smaller atomic nuclei to form a larger nucleus. Electromagnetic decay and gravitational collapse are not nuclear reactions involving these specific nucleus - changing processes.

Answer:

First blank: D. nuclear fission
Second blank: C. nuclear fusion
