Question

guided practice in addition to extreme pressure, what is required to achieve fusion of deuterium nuclei? a. nuclear energy b. extreme heat c. an atom splitter d. underground heat

Explanation:

Nuclear fusion of deuterium nuclei requires both extreme pressure and extremely high temperatures (tens of millions of degrees Celsius) to overcome the electrostatic repulsion between positively charged nuclei and allow them to fuse together. The other options are incorrect: nuclear energy is the output of fusion, an atom splitter relates to fission, and underground heat is unrelated to this fusion process.

Answer:

B. extreme heat
