According to Hubble's law what do the farthest galaxies in the universe appear to be doing?

Receding from each other faster the farther away they are. He saw they were "red shifted" and the red shift was greater the farther away the galaxy was.
This mean that the Universe is expanding.

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.
Was it difficult for Edwin hubbles ideas to be accepted?
All new ideas which upset the "current order" take a while to be accepted. The first expression of the heliocentric model of the solar system was by Aristarchus of Samos, 2400 years ago; it wasn't until Copernicus did his work that it became generally accepted. Galileo and Newton in physics overturned Aristotle. The theory of plate tectonics and continental drift was generally laughed at when I was in school. (But now you learn it IN school.) Sir Fred Hoyle coined the term "big bang" in mockery, compared to the accepted "steady state" theory. Luis Alvarez was derided as an insane madman for coming up with the impossible notion that a city-sized rock falling from space might have killed off the dinosaurs, and that was only 50 years ago! Now we (think we) know better. Every new idea goes through a weeding out process. Somebody makes a highly improbable assertion. Other scientists examine the idea, and try to come up with evidence for or against it. Somebody figures out a mechanism by which this might have happened. (Many "new ideas" disintegrate at these stages, and go no further. Not every "new idea" is true, and this weeding-out process is part of the "scientific method".)
According to hubbles law galaxies are retreating from earth at speed that is proportional to their?
distance
The implication of hubbles law is that the universe is?
That it is expanding.
What did Edwin Hubbles discovery of red shift demonstrate?
Edwin Hubble didn't discover redshift. What he did was make a systematic statistic of redshifts and blueshifts, of known galaxies. What this demonstrated was that the Universe is expanding.
What does Hubbles law tell us about the beginning of the universe?
It shows that in the past, galaxies were closer together; also, it suggests - as is commonly believed nowadays - that some time in the past, all matter in the Universe was very close together, in a very hot and dense state.
How old is the universe in 2011?
By using a therom call hubbles law and hubbles constant this is the calculation: 1/Ho=d/v=t t= 3.09x10 22/71000x31566926 t=13.738 billion years old
Why is Edwin hubbles invention important?
=Edwin Hubble's invention is important because the telescope its self showed over 50,000 space galaxies and planets. also it was made of cats=
Why do observations made of distant galaxies indicate that dark energy exists?
The observations made from distant galaxies suggest that Dark energy exists. This is because of the fact that the galaxies are moving away from each other. This is given by Hubbles law.Instead of being attracted by the force of gravitation,galaxies tends to move away suggesting the presence of a gravity opposing force called dark energy.
What is is hubbles law?
Hubble's Law states that (more or less) the distance to a galaxy is a constant multiple of the distance to that galaxy. For example, if one galaxy is moving away from us at three times the speed of another galaxy, then that means it is also three times as far away. The Law indicates that the Universe is expanding and had a beginning. Before Hubble's Law, many astronomers thought that the Universe did not have a beginning (it always existed).

Why was Edwin Hubbles theory important?
Hubble was an astrophysicist in the early 20th century. He helped discover the rate at which the universe is expanding, which is now given by the Hubble constant. (H0=69km s^-1 Mpc^-1)
