ASTRO 7N - UNIT 4 PART 2 (quiz)
What parameters do Hubble's law relate to every different?
Galaxy recession speed and distance
What technique for measuring distance can you operate to find out Hubble's regulation?
Cepheid variables in galaxies
white dwarf supernovae in galaxies
A&B
How do you degree the speed of a galaxy relative to you?
Doppler shifts
What is Hubble's law?
The faster a galaxy is shifting, the farther away it's miles.
Where is the middle of the Universe?
There is no center to the Universe. Expansion is occurring everywhere.
How have astronomers interpreted the all of sudden fast rotation of galaxies?
There have to be numerous darkish remember whose gravity can be felt but not seen
Which of the subsequent is not real about darkish depend?
Dark count number and darkish power are elements of the same phenomenon
Why will we think there is lots of dark depend in clusters of galaxies?
Individual galaxies are transferring so speedy that they couldn't be held together via the gravity
of seen remember
