Jason has 13720 J of gravitational potential energy standing at the top of a cliff over the lake. If he jumps off the cliff and falls to the water below, how much kinetic energy will he have when he reach the surface of the water?

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
