Q7. The sun has a lifetime of approximately 10 billion years. If you could determine the rate of nuclear fusion for a star with twice the mass of the Sun, which of the following would best describe how its fusion rate would compare to the Sun? Circle the best possible response to complete the sentence given belovw A star with twice the mass of the Sun would have a rate of nuclear fusion that is the rate of fusion in the Sun. a. less than b. a little more than c. twice dmore than twice Explain your reasoning for the choice you made

Explanation / Answer

A star with twice the mass of the sun would have a rate of nuclear fusion that is more than twice the rate of fusion in the sun.

Reason: Rate of nuclear fusion depends upon the mass of star. ( Arthur Eddington, stated that the source of stellar energy was fusion of hydrogen into helium, liberating enormous energy according to Einstein's equation (E = mc2).
