Question

which option would be an appropriate model of nuclear fusion? (1 point) mashing two marshmallows together adding a drop of water to a glass of water putting a puzzle together sewing one piece of fabric to another

Explanation:

Nuclear fusion is the process where two light - weight nuclei combine to form a heavier nucleus. Mashing two marshmallows together is a physical combination similar conceptually to the combination of nuclei in nuclear fusion. Sewing fabric is a mechanical joining of materials not related to nuclear processes. Putting a puzzle together is an assembly of separate pieces and not a model for nuclear fusion. Adding a drop of water to a glass of water is a process of combining the same substance in a non - nuclear way.

Answer:
