A person moves a book from a 30-cm high coffee table to the top shelf of a bookshelf approximately 2.5 m high. Which statement correctly describes the gravitational potential energy of the book? It has more gravitational potential energy on the table than on the shelf. It has more gravitational potential energy on the shelf than on the table. Its gravitational potential energy is constant regardless of its position.

Vander waals forces are inter molecular bonds that exist within molecules of the same substance. a water molecule is made up of oxygen and hydrogen atoms which share electrons between each other. the vander waals forces are forces that exist between multitude of different  molecules of water. dipole dipole forces is the type of vander waals force that exist in water. the oxygen atom which is more electronegative pulls the shared electron closer to itself thus generating a partial negative charge while the hydrogen acquire a partial positive charge. these two different charges causes attraction to occur in water molecules.
