1. What is the main function of valence electrons in chemical bonding?

• A. They are responsible for holding the nucleus together.
• B. They are involved in forming bonds with other atoms.
• C. They determine the element's physical properties.
• D. They play no role in chemical reactions.

Correct answer: B

Rationale: They are involved in forming bonds with other atoms. Valence electrons occupy the outermost energy level and are readily involved in attracting other atoms through sharing or transferring electrons, forming chemical bonds.

2. Stephanie is a new Staff Educator of a private tertiary hospital. She conducts orientation

• A. Organizational structure
• B. Policy
• C. Job description
• D. Manual of procedures

Correct answer: D

Rationale: The correct answer is D, 'Manual of procedures.' During orientation, Stephanie as a Staff Educator would likely refer to the manual of procedures to provide new employees with detailed instructions on how to perform their job duties. This manual outlines the specific procedures, protocols, and guidelines that employees are expected to follow within the organization. It serves as a valuable resource for new hires to understand the standard operating procedures and expectations within the hospital setting, making it a crucial document to reference during orientation.

3. What is the work done by a force of 20 N acting on an object that moves 5 meters in the direction of the force?

• A. 100 Joules (J)
• B. 25 Joules (J)
• C. 4 Joules (J)
• D. Work cannot be determined without knowing the object's mass.

Correct answer: A

Rationale: Work is defined as the force applied multiplied by the distance moved in the direction of the force. Work = force x distance = 20 N x 5 m = 100 J.

4. What is the waste product of protein digestion?

• A. Glucose
• B. Amino acids
• C. Fatty acids
• D. Ammonia

Correct answer: D

Rationale: Rationale: Protein digestion involves breaking down proteins into their constituent amino acids. During this process, the waste product produced is ammonia. Ammonia is a toxic compound that needs to be converted into urea in the liver and then excreted by the kidneys in the form of urine. Glucose is a product of carbohydrate digestion, amino acids are the building blocks of proteins, and fatty acids are the end products of fat digestion.

5. A baseball is thrown into the air. At the peak of its trajectory, which of the following forces is acting on the ball?

• A. Only gravitational force
• B. Only the force of air resistance
• C. Both gravitational force and the force of air resistance
• D. Neither gravitational force nor the force of air resistance

Correct answer: A

Rationale: At the peak, the ball momentarily stops moving upwards. Its inertia keeps it moving horizontally, but there is no force propelling it upwards except for gravity pulling it down.

6. How does kinetic energy change when the velocity of an object is doubled?

• A. Kinetic energy is halved
• B. Kinetic energy quadruples
• C. Kinetic energy doubles
• D. Kinetic energy remains the same

Correct answer: b

Rationale: Kinetic energy is directly proportional to the square of the velocity of an object.
