This phenomenon is known as Hubble's Law, which describes the relationship between the distance and the velocity at which galaxies are moving away from us. It is a key piece of evidence for the expansion of the universe.

How fast are galaxies moving away from each other in the expanding universe?

Galaxies in the expanding universe are moving away from each other at speeds proportional to their distance, with more distant galaxies moving faster. This phenomenon is known as the expansion of the universe.


At a given rotational speed how does linear speed change its distance from the axis changes?

In The Center Of The Rotating Platform Right At Its Axis You Have No Linear Speed At All, But You Do Have Rotational Speed. Your Rotational Speed would Stay The Same But As You Move Away From The Center Your Linear Speed Gets Faster And Faster. If You Move Twice As Much From The Center Your Linear (Tangential) Speed Would Also Be Twice as Much


What is the speed of an object 10m from you for 2 seconds?

To calculate the speed of an object, we need to know the distance it travels and the time it takes. If the object is 10m away from you and travels that distance in 2 seconds, we can calculate its speed using the formula: Speed = Distance/Time. In this case, Speed = 10m/2s = 5 m/s.


Does angular speed depend on distance?

when something moves with constant angular speed (w), as in a rotating disk, the speed (v) as you move away from the center depends on distance (r), but the angular speed does not. Mathematically, v = wr.


If mass stays the same and distance increases then the force of gravity does what?

If mass stays the same and distance increases, the force of gravity decreases. This is described by Newton's law of universal gravitation, which states that the force of gravity between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.

how distance to a galaxy and speed are related?

Relationship between distance of galaxy and its speed is that galaxies are moving away from the Earth at velocities proportional to their distance. In other words, the further they are the faster they are moving away from us.


He originally suggested that galaxies are moving farther away He also suggested that the distance of a galaxy is proportional to its recessional speed who is He?

Edwin Hubble.

How do the speeds at which most nearby galaxies are moving away from the earth compare to the speeds of distant galaxies that are moving away from earth?

Distant galaxies are moving away from Earth at faster speeds compared to nearby galaxies. This is due to the expansion of the universe, where galaxies farther away experience a greater redshift, indicating faster recession velocities. This relationship is described by Hubble's Law, which states that the recessional velocity of a galaxy is directly proportional to its distance from us.


Is a farther away galaxy from us moving away faster?

Yes, furthest the galaxy more it's speed of moving away from each other also universe is expanding continuously therefore space between galaxies is also expanding . Redshift is directly proportional to the distance b/w the galaxies therefore distant galaxies red-shifted at faster rate


According to Hubbles law galaxies are retreating at a speed that is proportional to their?

I'm not convinced that your proposition is correct. I realize that cosmologists use a lot of simplification in their descriptions, for friendly reasons, but I always prefer to keep things fairly straight. It is my reading of Hubble that he postulated that remote galaxies were receding -- at the time they emitted the light which we are now receiving -- from us at a speed which was proportional to the distance from where they were then to where we are now. How one interprets the concept of distance, in view of the separately postulated "expansion of space" and time-dependence of the "scaling factor" is obviously now a compounding, related issue, which lay outside Hubble's purview. Hubble's law does not specify, based upon the observed redshift (whether non-Doppler or not) what is (i.e. is now) the distance between us and the galaxy. It is considered simplest to assume that the velocity of separation is and continues radially uniform, and therefore has increased during the time it took the light to reach us. If you need to know the current (our observing time) location of the remote galaxy and the velocity of its separation from us now, you will need to apply further calculations to the Hubble data.


A decrease frequency of light from a galaxy would make the galaxy appear redder?

Yes, this is due to the redshift effect in cosmology where the wavelength of light from distant galaxies is stretched as the universe expands, causing the light to appear redder. This redshift is proportional to the distance of the galaxy, helping astronomers estimate how far away it is.


What conclusion do astronomers make based on the red shift?

Astronomers conclude that objects in the universe are moving away from Earth due to the observed redshift in their spectra. This supports the idea of an expanding universe, as described by the Big Bang theory. The amount of redshift is proportional to the distance of the object, allowing astronomers to estimate the speed at which galaxies are moving away from us.


Light year distance to the stars?

The closest star is the Sun - about 8 light-minutes away. The closest star after that is at a distance of 4.3 light-years; the farthest observable galaxies (galaxies are made up of stars) are at a distance of over 40 billion light-years.The closest star is the Sun - about 8 light-minutes away.

What does red shift tell us about other galaxies?

Red shift indicates that other galaxies are moving away from us, implying that the universe is expanding. This phenomenon is a key piece of evidence supporting the Big Bang theory. The amount of red shift is used to determine the distance and speed at which other galaxies are moving relative to us.


Who classified the galaxies according to shape and distance and concluded that galaxies move away from each other at a rate dependent to the distance between them?

Edwin Hubble, in the 1920s. Later they named a telescope after him.


Are any Galaxies moving away at half the speed of light or faster?

Yes. The farthest known galaxies move away from us faster than the speed of light. While this is not possible for nearby objects, in this case space itself is expanding.
