It is possible to derive the age of the universe given the value of the Hubble constant and the distance to a galaxy, again with the assumption that the value of the Hubble constant has not changed since the Big Bang. Consider a galaxy at a distance of 400 million light-years receding from us at a velocity, v. If the Hubble constant is 20 km/s per million light-years, what is its velocity

v = 8000 km/s = 8 x 10⁶ m/s

Explanation:

The velocity of the galaxy is given by the following formula:

where,

v = velocity of the galaxy = ?

c = Hubble's Constant = 20 km/s.million light years

d = 400 million light years

Therefore, using these values in the equation we, get:

v = 8000 km/s = 8 x 10⁶ m/s

conduction, convection, radiation

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.

not copied too! hope this !
