Determine if the following statement is true, false, or neither: if a galaxy’s redshift measured from earth implies that it is moving 8,000 km/s away from us owing to the expansion of the universe, an observer in every other galaxy in the universe will also measure a redshift for that galaxy corresponding to a velocity of 8,000 km/s.

Why does the equilibrium position of the spring change when a mass is added to the spring? will the mass oscillate around the new equilibrium position of the spring or the previous position without a mass attached to the spring? if the equilibrium position of the spring changes by 20 cm (assuming no initial mass) when a mass is added to the spring with constant 4.9 kg/s^2, what is the mass of the object attached to the spring?
