1. The formula for body mass index (BMI) is BMI = weight (kg) / height (m)^2. If a patient's BMI is 25 and their height is 1.7m, what is their weight?

• A. 34kg
• B. 45kg
• C. 56kg
• D. 68kg

Correct answer: C

Rationale: 56kg: Rearrange the formula to solve for weight: weight = BMI * height^2.

2. Which element has the highest melting point of any element?

• A. Tungsten
• B. Iron
• C. Platinum
• D. Carbon

Correct answer: D

Rationale: Diamond's strong covalent bonds between carbon atoms make it incredibly resistant to heat and pressure, giving it the highest melting point.

3. A person throws a ball horizontally. What force changes the direction of the ball's motion?

• A. The force of throwing
• B. Gravitational force
• C. Air resistance
• D. Normal force from the ground

Correct answer: B

Rationale: When a person throws a ball horizontally, the initial force that propels the ball forward is the force of throwing (A). However, the force that changes the direction of the ball's motion is the gravitational force (B), which acts vertically downward and causes the ball to follow a curved path. Air resistance (C) and normal force from the ground (D) do not directly change the direction of the ball's motion in this scenario.

4. The energy absorbed during a chemical reaction is called:

• A. Kinetic energy
• B. Potential energy
• C. Heat energy
• D. Endothermic energy

Correct answer: D

Rationale: Endothermic means "inward heat," indicating energy is absorbed during the reaction.

5. Which phrase best describes the relationship between smart grid technologies and renewable energy integration?

• A. Competitive and incompatible, hindering each other's effectiveness.
• B. Neutral and independent, neither impacting nor relying on each other.
• C. Complementary and synergistic, enhancing each other's functionality.
• D. Substitutable and interchangeable, offering equivalent solutions.

Correct answer: C

Rationale: The passage highlights the mutually beneficial relationship between smart grids and renewables, with both working together to optimize integration.

6. She knows that performance appraisal consists of all the following activities EXCEPT:

• A. Setting specific standards and activities for individual performance.
• B. Using agency standards as a guide.
• C. Determine areas of strength and weaknesses
• D. Focusing activity on the correction of identified behavior.

Correct answer: D

Rationale: The correct answer is D: 'Focusing activity on the correction of identified behavior.' Performance appraisal is a process that involves setting specific standards and activities for individual performance, using agency standards as a guide, and determining areas of strengths and weaknesses. While performance appraisal may identify areas for improvement, its primary focus is not solely on correcting behavior. Instead, it is a holistic evaluation of an individual's performance in various aspects. Therefore, option D is the exception among the activities associated with performance appraisal.
