Complete question:
use the hubble's law to determine the distance to a quasar receding at 75% the speed of light. The speed of light is 300,000 km/sec. assume Hubble's constant is 2.2 x 10⁻⁵ km/s/Lyr
Answer:
The distance to the quasar is 1.02 x 10¹⁰ Lyr
Explanation:
Given;
speed of light, v = 300, 000 km/sec
Hubble's constant, H₀ = 2.2 x 10⁻⁵ km/s/Lyr
percentage of the quasar recession = 75% of speed of light
Hubble's Law is given by;
Therefore, the distance to the quasar is 1.02 x 10¹⁰ Lyr
Assume that the average life expectancy is about 72 years, according to recently published data.
Therefore a generation is
72/3 = 24 years.
Therefore over the last 2,000years, the number of generations that have passed is
2000/24 = 83.3
Answer: 83 generations
Answer:
