Which wave travels faster through gas and why? A. Electromagnetic because they can move around the particles easier since they are spread out.

B. Electromagnetic because the particles can collide quicker since they are spread out.

C. Mechanical because they can move around the particles easier since they are spread out.

D. Mechanical because the particles can collide quicker since they are spread out.

a boiling water reactor does not boil the water. a pressurized water reactor boils the water faster. a pressurized water reactor is heated directly by the core. a pressurized water reactor does not use fission.

the awnser is group 12

answer is: nuclear fusion produces elements that are heavier than helium.

nuclei combine to form a heavier nucleus, releasing energy.  

for example, fusion of hydrogen atoms at the sun.  

this fusion nuclear reaction is in the inner core of the sun and hydrogen (atomic number 1) is conveted into helium (atomic number 2).  

the inner core is the central region of the sun and all solar energy is produced in the core by nuclear fusion.
