Gas cloud 1 is likely to form a star. Gas cloud 2 is not. Based on this information, match the given conditions with each cloud. 1. Its temperature stays well
below 14 million Kelvin.

2. Its volume shrinks and density
increases due to gravity.

3. Its temperature surpasses
14 million Kelvin.

4. It is spread out, with a greater volume and
lesser concentration of elements.

5. Its hydrogen atoms shed their electrons.

6. Its hydrogen atoms retain their electrons.

On a horizontal frictionless surface, a small block with mass 0.200 kg has a collision with a block of mass 0.400 kg. immediately after the collision, the 0.200 kg block is moving at 12.0 m/s in the direction 30° north of east and the 0.400 kg block is moving at 11.2 m/s in the direction 53.1° south of east. use coordinates where the +x-axis is east and the +y-axis is north.(a) what is the total kinetic energy of the two blocks after the collision (in ) what is the x-component of the total momentum of the two blocks after the collision? (indicate the direction with the sign of your ) what is the y-component of the total momentum of the two blocks after the collision? (indicate the direction with the sign of your answer.)
