Objects 1 and 2 attract each other with a electrostatic force of 18.0 units. If the distance separating Objects 1 and 2 is
doubled, then the new electrostatic force will be units.

Two models of the same compound are shown. in what way is model b better than model a? model b shows the types of elements in the compound, but model a does not. model b shows the three-dimensional shape of the molecule, but model a does not. model b shows how the atoms in the molecule are connected, but model a does not. model b shows the number of atoms of each element in the molecule, but model a does not
