- If a giant molecular cloud is 38 pc in diameter and a shock wave can sweep through it in 6 million years, how fast is the shock wave going in kilometers per second? (Notes: 1 pc = 3.1 1013 km; 1 yr = 3.2 107 s.) answer in km/sHow many Big Macs can fit in the Grand Canyon taking into account gravity and the varying dimensions of the Grand Canyon?Do you expect that most planetary systems in the Universe have analogs to our Solar System's asteroid belt and Kuiper Belt? Would all planetary systems show signs of an age of heavy bombardment?
- Looking for ___ pcQuestion 41 .Suppose you are looking at H-R diagrams of two similar star clusters. The most luminous main sequence stars in the Porcini cluster are much more luminous than the most luminous main sequence stars in the Morel cluster. What can you conclude? O the Porcini cluster is younger than the Morel cluster O the Porcini cluster is farther away than the Morel cluster O the Porcini cluster is lower in metallicity than the Morel cluster O the Porcini cluster is larger in diameter than the Morel cluster
