The capture of too few solar neutrinos by Davis in the solar neutrino experiment
a.
can be explained if the sun is not undergoing thermonuclear fusion of hydrogen in its core.
b.
indicates that the sun’s core is much cooler than expected.
c.
indicates that the sun’s core is much hotter than expected.
d.
indicates that the sun’s core is convective.
e.
is explained by none of the above.
1. When will the Sun exhaust its supply of hydrogen and no longer maintain the same
state of hydrostatic equilibrium that exists today? (Assume that the Sun will run out of
hydrogen fuel in its core, due to inefficient mixing, after 5% of the Sun's current total
hydrogen content is converted into helium.)
Why does nuclear fusion only take place in the Sun’s core?
