What is the mathematical equation for calculating the expansion of the universe?
v = H0D Where v is the velocity at which a galaxy moves away from us, and D is its distance. With H0 being the constant of proportionality (the Hubble constant) between the distance D to a galaxy and its velocity v.
What is meant by velocity distance relationship with regard to the expanding universe?
It means that, the farther away a galaxy is from us, the faster it moves away from us.
Where in the galaxy are high-velocity stars found?
in the halo
What is meant by the term velocity?
Velocity is a speed in a very specific direction.
What is the scientific rule describing the velocity of recession of galaxies?
it is when the galaxy doesn't have any moneys left and are homeless in the galaxy.
Do all stars belong to a galaxy or can a star exist without belonging to a galaxy?
They can be outside a galaxy. For a start, stars formed within a galaxy can be catapulted out of a galaxy (when they come close to another star, and change their velocity as a result).
What is meant by the acceleration of a body?
the rate of change in the velocity of a body
What is the next closest galaxy to Andromeda?
Canis Major Dwarf Galaxy. If you meant what's the closest spiral galaxy, then the answer is the Triangulum Galaxy.
How do you find distance with uniform velocity time final velocity and initial velocity?
If the velocity is uniform, then the final velocity and the initial velocity are the same. Perhaps you meant to say uniform acceleration. In any event, the question needs to be stated more precisely.
Why is the absolute value of velocity speed?
It's a scrambled equation. What you meant to say is, "The absolute value of velocity equals speed."
What is meant by rectangular triangle componenets of a vector?
If you plotted the original path and velocity, and the path and velocity of the 'impacting' force, then the third leg of the triangle will be the resultant path and velocity.
What two quantities did Edwin Hubble compare to discover the expansion of the Universe?
The Serperation of Galaxies which was caused by Dark Energy, and the Big Bang.
