Does it Make Sense?

Decide whether the statement makes sense (or is clearly true) or does not make sense (or is cleanly false). Explain clearly: not all of these have definitive answers, so your explanation is more important than your chosen answer.

Example: l walked east from our base camp at the North Pole.

Solution: The statement does not make sense because east has no meaning at the North Pole—all directions are south from the North Pole.

14. The universe is billions of light-years in age.

Blurred answer

1. Why were the main reasons why the idea that the Earth was at the center of the universe lasted so long? 2. Discuss in 2 paragraphs the observations made by Galileo that disproved Geocentrism. Which one do you think was the most important? 3. Write down a hypothesis and observational experiment to test one of Newton’s laws of motion. EXPLAIN YOUR REASONING! 4. One of the first exoplanets discovered orbits the star 51 Pegasi with a period of just 4.2 days. 51 Pegasi is very similar to the Sun. Use Kepler’s laws to find the distance (in astronomical units) between the planet (unofficially named Bellerophon) and its star. SHOW YOUR WORK! 5.  How does halving the distance between two objects affect the gravitational force between them? 6. Suppose the Sun were somehow replaced by a star with five times as much mass. What would happen to the gravitational force between the Earth and the Sun? 7. How long would the Earth year last in this last case? (hint: Newton’s version of Kepler’s 3rd…
