Saved if a moment vector is known in 3d space, how do we determine the resultant moment about a given axis? turn the moment into a linear force and apply it to the end of the axis multiple the moment vector by the length of the axis take the cross product of the moment vector and the axis vector dot product the moment vector with the unit vector of the axis

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.
