answer 36: it was not widely accepted or read when published. (it was never published)
answer 37: keplers laws explain why planets with large semi major axis have much longer orbital period (he didnt explain it was observation)
answer 38: A model can be used to explain and predict the real phenomenon
answer 39: Tycho collected data, kepler provided models in form of laws, newton explained model in terms of gravity
