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.

dec 23, 2016 - a load of bricks weighing 680 n a distance of 10 m across a parking lot. if if the worker pushes the cart with a constant force of 209 n, what work= force x distance = 220 n x 10 m = 2200 n.m = 2200 j i don't know where the person got it from, but the initial part, work= force x distance me.
