No light can escape from it. If the way we see things and colors is the light being absorbed and reflected, we cannot see a black hole if no light can be reflected. The only way scientists can tell if a black hole is present is the impact of it to the surrounding stars and gas.

Answer:
Ever since the ancient years, we have admired athletes and the hard work that they do to achieve their goal of winning. We idolize them and wish we were more like them. What happens though when the realization sinks in that they are human too and that some of them do get greedy and selfish? A lot of athletes are model citizens that you should really look up to, but there are also some bad apples in the bunch that ruins it for everyone. Athletes can inspire young people to work hard so that their efforts can pay off, but no one is pure and flawless. Greed does take a hold of some players, but they shouldn't be the ones we devote all of our attention to. We should look at the positive.Shaquille O'Neal bought over 1,000 turkeys and gave them to needy families all across the nation on Thanksgiving. I did not hear one mention of that in the news. They are making us believe that all athletes are bad people with their propaganda. Michael Jordan has started a foundation that donates money for research to help physically challenged children. Let a child believe in what they want to believe in. Sports athletes are good role models when they win and have confidence. It makes the child want that confidence and would push the child to achieve their goals to win just like that athlete. So athletes and celebrities aren´t all that bad to look up to.

Answer:
1.90× 10^4
Explanation:
The ratio of the equilibrium number of vacancies given in the problem statement (Nv= 2.3 x 10^25m^3) and the value of N is obtained using this formula N=NAp/A .
Thus;
The fraction of vacancies is equal to the Nv/Nratio.
Firstly the value of N is obtained with N=NAp/A
=( (6.022 x 10^23 atoms/mol)(5.60 g/cm3 )(10^6cm^3/m^3) )/65.6 g/mol
= 2.83 x 10^28atoms/m^3
The fraction of vacancies is Nv/Nratio:
Nv = 2.8x10^24 m^-3.
N = 2.83×10^28atoms/m^3
= 1.90× 10^4
