Answer #1

Hubble constant tells us about the speed of galaxies moving away from us. By the help of many instruments and observations or scientist had found that far the Galaxy is faster they are moving away the speed of the galaxy moving away and somewhat directly proportional to the distance of the galaxy from us. And that proportionality constant is called Hubbles constant

we can determine the Hubble constant by the slope of the graph plotting the velocity of the galaxy is moving away with respect to the distance of them from us.

9. The Hubble Law and Standard Candles. An elliptical galaxy called A lies at a distance of 20 Mpc (megaparsecs). What would the velocity inferred from the redshift of its spectral lines be for galaxy A? Assume a Hubble constant of 73 km/s/Mpc An identical elliptical galaxy called B with exactly the same luminosity as A is found to have a redshift exactly three times that of A. How does the measured brightness of B compare to that of A?...

The Hubble Ultra Deep Field led to the discovery of 10,000 galaxies in a small area of the sky covering 1.6×10−3 deg2 . It is estimated that there are 7.7 times more galaxies in that region of the sky which are too faint for the Hubble to see. Assume this area of the sky is representative of the full observable Universe from Earth. Clearly stating your assumptions, estimate: (i) The number of galaxies detectable with Hubble over the entire sky...

The Hubble time is defined as t​H = 1/H​0. Consider a Closed model for the Universe without a cosmological constant, so that the mass density parameter is Ω​M > 1. Give an expression for the age t​max (in units of t​H) of a Closed model at the time when the Universe has reached its maximum size, is no longer expanding, and is about to start contracting.

The Hubble Space Telescope orbits the Earth at an altitude of about 350 miles (570 km). The Earth has a radius of about 3950 miles (6350 km). The gravitational constant is G = 6.674 x 10-11 m3/kg/s2. The telescope has a mass of 11,110 kg. The Earth has a mass of 5.97 x 1024 kg. (Hint: Convert all distances to meters first.) a) What is the force of gravity on the telescope? b) How fast is the telescope orbiting around...
