In a low-density cloud, the internal pressure is much too low to support the weight, so the cloud must eventually producing the galaxy s disk.

The answer to this question is flatten

so the cloud must flatten eventually producing the galaxy s disk.

are there answer choices to this question? this seems like a question where you have options to choose from.

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
