Homework Help: physics

Posted by Misty on Sunday, April 17, 2011 at 7:52pm.

I keep getting the wrong answer...
A solar model is used to calculate the expected temperature and density at all depths within the Sun. These results are then used to calculate the expected fusion rate within the Sun. We have confidence that the model is correct because it agrees with the observed characteristics of the Sun. Which of the following observations can be used to check that we really do know the Sunís internal fusion rate?
Select all that apply.

-Measurements of the Sunís total energy output into space
-Measurement of the Sunís mass
-Observations of neutrinos coming from the Sun
-Observations of the total X-ray emission from the Sunís corona
-Measurements of the varying number of sunspots on the Sun over time
