Question

what is the difference between hot dark matter and cold dark matter? (select all that apply.) hot dark matter moves much faster than cold dark matter. cold dark matter moves much faster than hot dark matter. hot dark matter clumps easily into large structures, while cold dark matter does not. cold dark matter clumps easily into large structures, while hot dark matter does not. cold dark matter has a positive charge, while hot dark matter has a negative charge. hot dark matter has a positive charge, while cold dark matter has a negative charge. how does this difference affect cosmology? cold dark matter is more likely to clump together into structures such as galaxies. hot dark matter is more likely to clump together into structures such as galaxies. both hot and cold dark matter is required for the successful formation of galaxies.

Answer 1

Hot dark matter moves faster than cold dark matter and does not clump into large structures, while cold dark matter moves slower and clumps easily. This difference affects the formation of galaxies.

Step-by-step explanation:

The difference between hot dark matter and cold dark matter lies in their average velocities and ability to clump into structures. Hot dark matter particles move faster than cold dark matter particles. Hot dark matter does not clump easily into large structures, while cold dark matter does. This difference affects cosmology by influencing the formation of galaxies. Cold dark matter is more likely to clump together into structures such as galaxies, while hot dark matter is less likely to do so. Both hot and cold dark matter are required for the successful formation of galaxies.
