Direction: Read the given passage and answer the following questions.

Nuclear physics is a branch of physics that studies the components and behavior of atomic nuclei. This field delves into understanding the forces that hold the nucleus together, the interactions between protons and neutrons, and the energy transformations that occur within the nucleus. Key concepts include nuclear reactions, radioactive decay, and nuclear fusion and fission. Nuclear reactions can either release or absorb significant amounts of energy, making them fundamental to both natural processes and technological applications.

One of the most well-known applications of nuclear physics is nuclear energy, which is harnessed through controlled nuclear fission reactions in reactors to generate electricity. Another vital application is in medical technology, where radioactive isotopes are used in diagnostic imaging and cancer treatment.
