The pressure of water in the pipe___to the electric potential.
举一反三
- Hydropower systems build pressure either by containing the water behind a dam, or within a pipe that runs down a hill. The weight of the water behind the dam or in the pipe creates pressure at the bottom. More height creates more pressure, and more pressu
- Both electric field E and electric potential V can describe the characteristics of a field. If the electric potential at a certain point is zero, the electric field at that point has to be zero.
- Which statement as follows is right? A: The potential equals everywhere the magnitude of electric field intensity is equal. B: The magnitude of electric field intensity equals everywhere the potential is equal. C: The potential must be high where the magnitude of electric field intensity is great. D: The potential is not necessarily zero where the magnitude of electric field equals zero.
- （） at the end of the distribution pipe ensures that adequate pressure is maintained by the pump.
- Which is false? A: Streamlines and equipotential surfaces are perpendicular everywhere. B: Streamlines point from the position with lower potential to the position with higher potential. C: Streamlines do not intersect. D: The tangential direction of the streamline is the direction of the electric field intensity at the point.
