Answer:
C
Explanation:
It's not A because you can't use a knife to cut an atom nucleus. Its size is not perceptible to the eye.
It's not B because when two nuclei collide and combine into one, it's call fusion.
It's not D because you can't have stronger forces than the ones holding the nucleus together.
The correct answer is C.
To fission, the nucleus needs to have at least two things: critical mass (only big ones can fission spontaneously) and instability (incorporate a neutron ).
Answer: V = 5.1 L
Explanation: To find the new volume, we will use the formula of Combined Gas Law and derive V2. We also need to convert first the temperature in Kelvin and convert torr to atm ( 1 atm = 760 torrs ).

Answer:
If damage is done to the human skeletal structure it cannot be healed or reversed: INCORRECT.
Explanation:
- Human DNA is capable of repairing itself: <em>CORRECT.</em> It has several ways to do it, repairing bases through excision, by photoreactivation, repairing mismatches, by repairing double-strand breaks and activating SOS responses.
- If damage is done to the human skeletal structure it cannot be healed or reversed:<em> INCORRECT.</em> The human body has a bone healing process that allows the creation of a cartilaginous scaffold than then becomes a bone matrix transforming the outer laminar bone into compact bone.
- The human skin is capable of self-heal due to the human cells: <em>CORRECT. </em> A wound in human skin is healed in a process that includes hemostasis, the creation of a blood clot, followed by an inflammatory phase and de successive creation of new epidermis. Many human cells are involucrated, such as fibroblasts and macrophages.
- When synthetic material gets damaged it's irreversible: <em>CORRECT. </em>These kinds of materials do not have a system to self-heal by itself.
- Biological material has the capability of healing due to vascularity and its cells: <em>CORRECT.</em> Vascularization is the growth of blood vessels, it is fundamental to have effective transport of oxygen, nutrients, and removal of cell-secreted waste for the survival of cells, this allows the biological material to heal.

Answer:
According to research,
The average speed of an object is the distance traveled divided by the time elapsed(taken).
Velocity and average velocity can be defined as the displacement divided by the time.
