1. According to Newton's third law of motion, for every action, there is an equal and opposite ___________.

• A. Reaction
• B. Force
• C. Acceleration
• D. Momentum

Correct answer: a

Rationale: Newton's third law states that for every force or action, there is an equal and opposite reaction.

2. He asserts the importance of promoting a positive organizational culture in their unit. Which

• A. Proactive and caring with one another
• B. Competitive and perfectionist
• C. Powerful and oppositional
• D. Obedient and uncomplaining

Correct answer: A

Rationale: The correct answer is A: 'Proactive and caring with one another.' When promoting a positive organizational culture, it is essential to foster a supportive environment where individuals are proactive in their approach and demonstrate care towards one another. This type of culture encourages collaboration, open communication, and empathy among team members, leading to higher levels of job satisfaction and overall performance. Being competitive and perfectionist (option B) can create a stressful and unhealthy work environment, while being powerful and oppositional (option C) or obedient and uncomplaining (option D) can stifle creativity and innovation. Therefore, the most suitable traits for promoting a positive organizational culture are being proactive and caring with one another.

3. The process of splitting a heavy nucleus into smaller nuclei, releasing a vast amount of energy, is called:

• A. Nuclear fusion
• B. Nuclear fission
• C. Radioactive decay
• D. Chain reaction

Correct answer: B

Rationale: Rationale: Nuclear fission is the process of splitting a heavy nucleus into smaller nuclei, releasing a vast amount of energy. This process is commonly used in nuclear power plants and nuclear weapons. A) Nuclear fusion is the process of combining two light nuclei to form a heavier nucleus, releasing energy in the process. This process powers the sun and other stars. C) Radioactive decay is the process by which an unstable atomic nucleus loses energy by emitting radiation. D) Chain reaction is a self-sustaining reaction in which the products of one reaction event stimulate further reaction events. This can occur in both nuclear fission and nuclear fusion reactions.

4. Beta waves, associated with alertness and focused attention, typically fall within the range of:

• A. 0.5-4 Hz
• B. 4-8 Hz
• C. 8-13 Hz
• D. 13-30 Hz

Correct answer: D

Rationale: Beta waves are neural oscillations in the brain that are associated with alertness, concentration, and active thinking. They typically fall within the frequency range of 13-30 Hz. This range is indicative of a person being awake, alert, and engaged in cognitive tasks requiring focus. Lower frequency ranges like 0.5-4 Hz (Delta waves) are associated with deep sleep and unconsciousness, while higher ranges like 8-13 Hz (Alpha waves) are linked to a relaxed and meditative state. Therefore, option D (13-30 Hz) is the correct range for beta waves, reflecting the brain's heightened activity during periods of attentiveness and concentration.

5. What happens when an atom loses an electron?

• A. It becomes a molecule.
• B. It gains a positive charge and becomes an ion.
• C. It changes its element identity.
• D. Nothing happens, it remains neutral.

Correct answer: B

Rationale: It gains a positive charge and becomes an ion. Losing an electron disrupts the charge balance, leaving the atom with more protons than electrons and a positive charge.

6. Which part of the nervous system is responsible for transmitting signals from the sensory organs to the central nervous system?

• A. Autonomic nervous system
• B. Somatic nervous system
• C. Peripheral nervous system
• D. Central nervous system

Correct answer: C

Rationale: The correct answer is C: Peripheral nervous system. The peripheral nervous system is responsible for transmitting signals from the sensory organs to the central nervous system. It consists of nerves outside of the brain and spinal cord that carry information to and from the central nervous system. The autonomic nervous system (A) regulates internal bodily functions, the somatic nervous system (B) controls voluntary movements, and the central nervous system (D) includes the brain and spinal cord where processing of signals occurs, rather than transmitting signals from the sensory organs.
