Avertical pipe, closed at the bottom end, is filled to a depth of 1.00 m with water and then an amount of oil of density 0.800 x 10^3 kg/m^3 is added to make the total depth 2.00 m. the oil and water don't mix with the oil floating on top of the water. what is the increase in pressure at the bottom end of the pipe as a result of adding the fluids?

Assume that two of the electrons at the negative terminal have attached themselves to a nearby neutral atom. there is now a negative ion with a charge -2e at this terminal. what are the electric potential and electric potential energy of the negative ion relative to the electron? the electric potential and the electric potential energy are both twice as much. the electric potential is twice as much and the electric potential energy is the same. the electric potential is the same and the electric potential energy is twice as much. the electric potential and the electric potential energy are both the same. the electric potential is the same and the electric potential energy is increased by the mass ratio of the oxygen ion to the electron. the electric potential is twice as much and the electric potential energy is increased by the mass ratio of the oxygen ion to the electron.
