1.) plates move at a speed of 1 centimeter per year. How long woul it take for two continents 3000kilometers apart to collide? (can you please show your work on how you got the answer. thanks)
2.) Io orbits Jupiter at an average distance of 421,600 kilometers and with an orbital period of 1.77days. Use these facts and newton's version of kepler's 3rd law to calculate jupiters mass
3.) if the jovian planets atmospheres were composed only of hydrogen and helium, with no hydrogen compunds at all, what would their atmosphere be diff, in terms of clouds, color, and weather. explain
