The sun produces 3.826 x 1026 joules of energy every second as it combines smaller hydrogen atoms into larger helium atoms. what is the name of the process which allows for the production of so much energy?
a) fission
b) fusion
c) heation
d) photosynthesis

I think the correct answer from the choices listed above is option B.  The name of the process which allows for the production of so much energy in the sun would be fusion reaction. It is a nuclear reaction in which two or more atomic nuclei come close enough to form one or more different atomic nuclei and subatomic particles

It indicates no change in temperature and the process of matter changing its state

The objects are acted upon by only one force. gravity. mass times the acceleration of gravity (-9.81meters/second squared).
