... Protostars and protostellar collapse are likely triggered by turbulent gas, e.g. a shock wave hitting a molecular cloud or highly supersonic turbulent flow within molecular clouds. Local density enhancements due to compression becomes gravitationally unstable if larger than the Jeans length λ ...

... while they are stopping? Can you bench press that much weight? (divide the force by 2.2 kg per pound to determine the weight in pounds). How do seat belts and air bags help keep people safe during accidents? 6. Julie is at rest in her 1502 kg car at a red light. A 2000 kg car behind her, moving at 4 ...

As the density increases, the cloud becomes opaque, trapping the heat within the cloud. This then causes both the temperature and pressure to rise rapidly ...
