Answer:
The core turns its hydrogen to helium and stops nuclear fusion which causes the outer shells of hydrogen to collapse.
Explanation:
This results in higher temperature and pressure which in turn causes the outer shells to expand and cool as a red giant.
The spring constant determines how far the spring will stretch for a given applied force: <span>F=kx→k=<span>Fx</span></span><span>. If we place the same mass on the two springs, which means we have placed the same force on them, the one that stretches </span>least<span> has the largest spring constant.
Hope this helps!

Answer:
B
Explanation:
to find how many moles we have you need to use the molarity equation which for this is
40g * (1mole/200g) = .2 moles
Given we know that we have .2 moles
then all you have to do is divide amount of moles by amount of liters to find the molarity
for this problem it is
.2mol/2L which is .1 M
