The sun makes its own energy through a process called

a. radiation
b. combustion
c. nuclear fusion
d. nuclear fission

nuclear fusion, because it combines the atoms to create massive amounts of heat, and energy, if it were radiation, it'd just be a giant ball of stale power that wouldn't do anything, and you should already know that the sun doesn't explode to create energy. As applies for fission, it doesn't deconstruct it's self to create energy

hope this helps!

when insulating materials rub against each other, they may become electrically charged . electrons , which are negatively charged, may be 'rubbed off' one material and on to the other. the material that gains electrons becomes negatively charged. the material that loses electrons is left with a positive charge.
