Arrange the following stars in order of their evolution:
a star with no nuclear reactions going on in the core, which is made primarily of carbon and oxygen.
a star of uniform composition from center to surface; it contains hydrogen but has no nuclear reactions going on in the core.
a star that is fusing hydrogen to form helium in its core.
a star that is fusing helium to carbon in the core and hydrogen to helium in a shell around the core.
a star that has no nuclear reactions going on in the core but is fusing hydrogen to form helium in a shell around the core.

1. A star of uniform composition from center to surface; it contains hydrogen but has no nuclear reactions going on in the core.

2. A star that is fusing hydrogen to form helium in its core.

3. A star that has no nuclear reactions going on in the core but is fusing hydrogen to form helium in a shell around the core.

4. A star that is fusing helium to carbon in the core and hydrogen to helium in a shell around the core.

5. A star with no nuclear reactions going on in the core, which is made primarily of carbon and oxygen.

explanation:

physics means: "the branch of science concerned with the nature and properties of matter and energy. the subject matter of physics, distinguished from that of chemistry and biology, includes mechanics, heat, light and other radiation, sound, electricity, magnetism, and the structure of atoms."

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg
