A (light) pallet has a load of cases of tomato paste each of which is a cube of length L and has identical mass. Find the center of gravity in the horizontal plane, so that the crane operator can pick up the load without tipping it. (Use the following as necessary: L, measured from the back left corner.)

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
