(a) slows down as ordinary matter particles collide.
(b) experiences a strong gravitational pull.
(c) is lighter than dark matter.
(d) is not affected by dark energy.
The correct option for the statement “In a huge cloud ordinary and dark matter are uniformly mixed together. Over time, the ordinary matter becomes concentrated toward the center of this cloud because ordinary matter”.
Answer to Problem 9RAT
The correct option for the statement “In a huge cloud ordinary and dark matter are uniformly mixed together. Over time, the ordinary matter becomes concentrated toward the center of this cloud because ordinary matter” is option (b).
Explanation of Solution
In a huge cloud, ordinary and dark matter are uniformly mixed together. Over time, the uniformly matter becomes concentrated towards the center of this cloud because ordinary matter experiences a strong gravitational pull. Dark matters are matters that are not visible. These are responsible for the major contribution to the total energy of the universe.
As the dark matter and ordinary mater uniformly mixed together, the uniformly matter experiences a gravitational pull by the dark matter and concentrated towards the center.
Conclusion:
Therefore, the correct option for the statement “In a huge cloud ordinary and dark matter are uniformly mixed together. Over time, the ordinary matter becomes concentrated toward the center of this cloud because ordinary matter” is option (b).
