This could be Hubble's law, or something related to it. I think there's a possibly Doppler RED SHIFT in the optical spectra of stars etc as observed on the earth. It seems that they are accelerating away from the earth, and that the further away they are the faster they are moving.
It seems that this has been connected to the idea of "The Big Bang" theory of the origin of the universe which seems to have superceded Professor Sir Fred Hoye's Steady State theory of the universe.
There's some Special Relativity in this lot, too.
The reason being nuclear reactions are slow in less massive stars than in massive stars hence they age slowly.
1) Time to get the highest point of it pathway>
Vf = Vo - g*t
Vf = 0 (condition of maximum height)
Vo = 5.33 m/s
g = 9.81 m/s
=> t = Vo / g = 5.33 m/s / 9.81 m/s = 0.543 s
2) Time to return from the highest point = time to get to the highest point = 0.543 s
Total time = 0.543s + 0.543 s = 1.086 s ≈ 1.09 s
Answer: 1.09 s
Halogens have 7 valence electrons, which probably explains why they are the most active non-metals.
<span>T1 = 20.0 + 273 = 293.0 K
T2 = 8.00 + 273 = 281.0 K
use the combined gas law
p1V1/T1 = p2V2/T2
765 x 580/ 293.0 = 440 V2/ 281-0
V2 = 967 mL</span>
