Suppose that observers using the Hubble Space Telescope detect, around several solar-type stars, the presence of planets with the following characteristics: low density; large size; polar diameters shorter than equatorial diameters; fluid surfaces; and rapid rotation. How would these planets be classified in terms of our solar system?

3. on your graph, the data points between the black squares are data for elements with atomic numbers 3 through 9. locate these elements on your periodic table. what term or description would you use to identify these elements with respect to the periodic table?

The graph describes the motion of an object. the object moves with from a to b. it from b to c. it moves with from c to d.

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.
