which statement is true about nuclear fusion? it is caused by the same process that causes nuclear fission. it does not occur naturally in the solar system. it has very low activation energy. it produces nearly all the elements that are heavier than helium.
Answer
Brief Explanations:
Nuclear fusion is the process of combining light - weight nuclei to form heavier ones. It occurs in the sun and other stars, providing the energy output. It is not the same process as nuclear fission (which is splitting of heavy nuclei). It has a high activation energy as it requires bringing positively - charged nuclei close together. It is responsible for producing nearly all elements heavier than helium through stellar nucleosynthesis.
Answer:
It produces nearly all the elements that are heavier than helium.
