Planet Caprica follows a largely circular orbit around its host star. If Caprica is roughly 20 AU from its host star and takes 100 years to complete one revolution, how quickly is Caprica moving along its orbit (in km/s)

Describe different biomes. what are some adaptations that organisms (plants or animals) must have to live in each biome?

Aplane travels 1000 miles in 5 hours .what is the planes average speed?

Cells in the nervous system have a potential difference of 70 mv across the cell membrane separating the interior of the cell from the extracellular fluid. this potential difference is maintained by ion pumps that move charged ions across the membrane. is this an emf? select the correct answer and explanation. 1)no. the ion pumps cannot separate charges; thus, they cannot create a potential difference. 2)yes. the ion pumps cannot separate charges, but they still can create a potential difference. 3)yes. the ion pumps can actively separate charge; thus, they can create a potential difference. 4)no. the ion pumps can separate charges, but they cannot create a potential difference.
