Which statement best explains why art that illustrates bonding in water uses dashed lines for hydrogen bonds and solid lines for the bonds inside each molecule? A. Hydrogen bonds are repulsive forces, and the bonds inside each molecule are attractive forces.

B. Hydrogen bonds are permanent forces of attraction and are much harder to break than the temporary bonds inside each molecule.

C. Hydrogen bonds are attractive forces, and the bonds inside each molecule are repulsive.

D. Hydrogen bonds are temporary forces of attraction and are much easier to break than the bonds inside each molecule.

chemical energy --> gravitational potential energy --> kinetic energy --> elastic potential energy --> gravitational potential energy

explanation:

when emma starts the hike, the chemical energy stored in her body is used to climb up the mountain, and so she gains gravitational potential energy (because at the end, she will be at a higher height h above the ground). then she goes bungee jumping: as she falls, this gravitational potential energy is converted into kinetic energy (because her speed increases as she falls down), until the point when the rope stretches, and she stops moving. at that moment, all the kinetic energy is converted into elastic potential energy due to the stretching of the rope. then, this energy is released because the rope returns to its natural length, and emma gains a small increase in altitude , so she gains some gravitational potential energy.
