Are the centipede and copepod closely related?

No. Centipedes are not actually insects, but are arthropods related to insects, while copepods are tiny crustaceans.

Centipede are predators, feeding on small, living creatures such as insects, spiders, and other arthropods, like sowbugs, and millipedes. They use poison-filled jaws to help subdue their prey. Because of their predaceous habits, centipedes are beneficial arthropods.

The most common centipede is called the house centipede. When full grown, it is more than an inch long. It has a flattened body with 15 pairs of long, jointed legs attached along the sides, one pair of legs per body segment.

Aquatic crustaceans, copepods, are very diverse and are the most numerous metazoans in the water community ("metazoan" means all multi-celled animals).

Copepod habitats range from fresh water to hypersaline conditions, from subterranean caves to water collected in bromeliad leaves or leaf litter on the ground and from streams, rivers, and lakes to the sediment layer in the open ocean. Their habitats also range from the highest mountains to the deepest ocean trenches and from the cold polar ice-water interface to the hot active hydrothermal vents.
