1. Explain why it only appears that we are at the center of expansion of the universe and why an observer in another galaxy would see the same relative motion of all but the closest galaxies away from her.
2. If there is no observable edge to the universe, can we determine where its center of expansion is? Explain.
A rocket, away from all gravitational forces, accelerates upward at an acceleration of 12.8m/s^2. On its main deck is a crate with a mass of 81.6kg. a) How many forces act on the crate? b) Determine the Normal force on the crate, & c) What would the ..
