The correct answer is option C "determine how a star is moving (toward, away, fast, slow)"
Explanation:
All realized components emanate and assimilate specific frequencies of light, which is important for the electromagnetic range. By considering the frequencies of light (as demonstrated by 'lines' inside the electromagnetic range) discharged by an object in space, astronomers can get a scope of information.
One thing they look at is the adjustment in situation of lines in the range from a star this can tell astronomers the distance away the star is, regardless of whether it is moving towards or away from us and how quick it is moving.
There was a release of immense heat within the bodies as they collided together as gravitational potential energy was converted into kinetic energy of the individual gas particles and then collisions between these particles converted this energy into heat.
I do know that the bird's beaks that they are born with will in time evolutionize their beaks size and strength to prey on the type of fish for food over time.
