Suppose astronauts are in a spaceship moving relative to the Earth at a significant fraction of the speed of light. (a) Do they observe the rate of their clocks to have slowed? (b) What change in the rate of Earth-bound clocks do they see? (c) Does their ship seem to them to shorten? (d) What about the distance between stars that lie along their motion? (e) Do they and Earth-bound observers agree on their velocity relative to the Earth?

The bubbles in a carbonated soft drink are produced when carbonic acid decomposes to form carbon dioxide and water. in a closed system, this equilibrium exists as why does a carbonated soft drink lose carbonation when the container is left open? a.water evaporates, which favors the formation of h2co3. b.pressure decreases, which favors the formation of h2co3. c.the open container warms up, which causes more gas to escape. d.co2is removed, which favors the formation of h2co3.
