Answer : Option C) The kinetic energy decreases as potential energy increases.
Explanation : As the target is fired high on the wall, the change in the energy that is observed as the arrow moves towards the target is kinetic energy starts to decrease as the arrow reaches nearer towards the target and the potential energy is observed to increase. So, in short the energy transformation is from kinetic energy from a moving arrow to potential energy when the arrow hits the target.
(2) subtracting the atomic number from the atomic mass number, because the mass number is the total number of protons and neutrons in an atom and the atomic number is the number of protons in an atom.
