At a given location in space, the potential is known to be greater when one moves in any direction. To be more specific, no matter which direction one goes, a small step in that direction results in an increase in the potential by the same amount. This means that the Electric field at this location is
A. Can take on any value at all. B. Zero C. Negative D. Positive
Why are there no impact craters on the surface of Io?
A) It is too small to have been bombarded by planetesimals in the early solar system. B) Any craters that existed have been eroded through the strong winds on Io's surface. C) Jupiter's strong gravity attracted the planetesimals more strongly than Io, and thus none landed on its surface. D) Io did have impact craters, but they have all been buried in lava flows. E) Io's thick atmosphere obscures the view of the craters.
