A charged particle moving at constant velocity will not create electromagnetic waves, but that same particle moving with a changing velocity (an acceleration) will create electromagnetic waves. Why? A.
Because electric forces and magnetic forces cancel out as a particle reaches a specific acceleration threshold.
B.
Because accelerating charges create changing electric fields, and the changing electric fields induce changing magnetic fields.
C.
Because only accelerating charges can repel their own electric fields, thus creating ongoing forward motion.
D.
Charged particles can accelerate only if they are in a vacuum, and since electromagnetic waves do not need a medium, they are created under vacuum conditions.

What is one benefit of a non renewable resource, such as natural gas? a. generates large amounts of electricity b. less expensive c. produces pollution d. will run out eventually

Nteractions between organisms and their environment impact the organism’s overall population. oahu amakihi and kauai amakihi are two closely related species of hawaiian honeycreepers. they have a common ancestor, eat small insects and nectar, and like to nest in koa trees. however, one species is found on the island of oahu, and the other is found on the island of kauai. which concept shows the relationship between oahu amakihi and kauai amakihi?
