Create a page showing data for each Abell cluster, presented so it's easy to see each cluster's average redshift and distance (e. g. Abel 1064: z=0.034, d=250 Mpc) and a short paragraph stating: The Hubble constant you found, H0, with (a realLinks to an external site.) citation. The distance to the furthest cluster you measured, in megaparsecs. The lookback time to that cluster in years (see step 6). To put that number in context, use Smithsonian's Interactive Timeline of Earth (Links to an external site.) to answer the question, "What was Earth like when the light from these galaxies started its journey?"

Identify the amplitude on the diagram and give the correct description. question 3 options: a because amplitude is the distance from wave crest to wave crest. b because the wavelength shows amplitude. c because amplitude is the distance between a crest (or trough) and rest. d because wavelength show amplitude.

If a balloon is taken outside on a very cold day, what will occur?

Aperson gives a shopping cart an initial push along a horizontal floor to get it moving, and then lets go. the cart travels forward along the floor, gradually slowing as it moves. consider the horizontal force(s) on the cart while it is moving forward and slowing. which of the following statements is correct? (a) both a forward and a backward force are acting on the cart, but the forward force is larger. (b) only a forward force is acting which diminishes with time. (c) both a forward and a backward force are acting on the cart, but the backward force is larger. (d) only a backward force is acting, no forward force.
