Question

In its core the Sun changed, hydrogen into helium and produces energy by this nuclear fusion process. Each hydrogen atom has a positively charged center (a proton) and a negatively charged electron that exists around the periphery of the atom. The heat of the Sun pulls the electrons off the hydrogen atoms, leaving positively charged protons behind. To make energy the sun has to force these positively charged particles very close together so that a very strong but short range force makes them stick together. Do the electrical forces between the hydrogen nuclei (the protons) make help or inhibit this process? They make it easier They make it more difficult The electrical forces are not relevant to this process Coulomb's Law doesn't apply at the core of the Sun Suppose we were able to make the constant ke have a larger numerical value. How would that affect the energy producing process in the Sun? There would be no effect The amount of energy that the Sun produces would decrease (the Sun would become dimmer and the Earth colder) The amount of energy that the Sun produces would increase (the Sun would get brighter and the Earth warmer) None of the above

Answer 1

1. option C

2. option C

Answer 2

35. (b)

Collisions of atoms within the core eventually become so energetic that electrons are stripped from their nuclei, leaving free electrons and hydrogen protons (a plasma as we now understand it).t the temperatures given by standard gas laws are not sufficient to provoke nuclear fusion. They cited the
