Can you think of any common ""real-life"" situations in which an understanding of conservation would allow a concrete operational child to react differently than a preoperational child? Provide several examples in the space below.

Which composition of water moves to begin a deepwater current?

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.

Two point charges are separated by a certain distance. how does the strength of the electric field produced by the first charge
