Answer the following question given this paragraph: Figure 32.19 Nuclear fusion in the Sun converts hydrogen nuclei into helium; fusion occurs primarily at the boundary of the helium core, where temperature is highest and sufficient hydrogen remains. Energy released diffuses slowly to the surface, with the exception of neutrinos, which escape immediately. Energy production remains stable because of negative feedback effects. Q: What process converts the sun's hydrogen nuclei into helium? Choices: - solar fission - nuclear fission - combustion - nuclear fusion A:
(A).
nuclear fusion
Ques:Answer the following question given this paragraph: Electric devices, such as lights and household appliances, change electric current to other forms of energy. For example, an electric stove changes electric current to thermal energy. Other common devices, such as mobile phones and computers, use electric current for another purpose: to encode information. A message encoded this way is called an electronic signal , and the use of electric current for this purpose is called electronics . For an overview of electronics and electronic signals, read the short article at this URL: http://www. bbc. co. uk/scotland/learning/bitesize/standard/physics/electronics/overview_rev1. shtml . Q: An electric stove changes electric current to what form of energy? Choices: - thermodynamic - kinetic - nuclear - thermal A:

Ans:thermal
