You are piloting a small airplane in which you want to reach a destination that is 750 km due north of your starting location. once you are airborne, you find that (due to a strong but steady wind) to maintain a northerly course you must point the nose of the plane at an angle that is 22◦ west of true north. from previous flights on this route in the absence of wind, you know that it takes you 3.14 h to make the journey. with the wind blowing, you find that it takes 4.32 h. a fellow pilot calls you to ask about the wind velocity (magnitude and direction). what is your report?

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.
