1. How does an increase in surface area affect the force of friction between two surfaces?

• A. Increases friction
• B. Decreases friction
• C. Has no effect on friction
• D. Causes unpredictable changes in friction

Correct answer: b

Rationale: Increasing surface area reduces the force per unit area, decreasing friction.

2. Why are isotopes of the same element chemically similar?

• A. They have the same number of protons.
• B. They have the same number of electrons.
• C. Their chemical properties are identical.
• D. They share the same electron configuration.

Correct answer: A

Rationale: They have the same number of protons. This determines the element's identity and its interactions with other elements, leading to similar chemical behavior, even if the number of neutrons differs.

3. Which element has the lowest electronegativity value?

• A. Oxygen
• B. Fluorine
• C. Helium
• D. Chlorine

Correct answer: C

Rationale: Electronegativity is the tendency of an atom to attract electrons towards itself in a bond. Noble gases like helium have very low electronegativity because their outer electron shell is already full and stable.

4. Harry is a Unit Manager I the Medical Unit. He is not satisfied with the way things are going

• A. Call for a staff meeting and take this up in the agenda.
• B. Seek help from her manager.
• C. Develop a strategic action on how to deal with these concerns.
• D. Ignore the issues since these will be resolved naturally.

Correct answer: A

Rationale: Choosing option A, 'Call for a staff meeting and take this up in the agenda,' is the best course of action for Harry as a Unit Manager. By calling for a staff meeting, Harry can openly address his concerns with the team, gather input from team members, and work collaboratively to find solutions. This approach promotes transparency, communication, and teamwork, which are essential in resolving issues within a unit. Seeking help from his manager, as suggested in option B, may be necessary in some cases, but initiating a discussion with the staff first allows for a more inclusive problem-solving process. Developing a strategic action, as in option C, is important, but involving the team in this process through a staff meeting is crucial for buy-in and implementation. Ignoring the issues, as in option D, is never a productive approach as unresolved issues can escalate and impact team morale and performance. Therefore, option A is the most effective and proactive way for Harry to address hi

5. A study finds a link between increased sugar intake and obesity. Does this confirm sugar causes obesity?

• A. Yes, the study definitively proves causation.
• B. No, correlation does not equal causation, other factors might be involved.
• C. We need more research to isolate the specific role of sugar.
• D. This only applies to people with genetic predispositions to obesity.

Correct answer: C

Rationale: Correlation suggests a link, but other factors might contribute. Further research is needed to establish the direction and strength of any causal relationship.

6. What property of a substance measures the amount of matter per unit volume?

• A. Mass
• B. Weight
• C. Density
• D. Volume

Correct answer: c

Rationale: Density measures the amount of matter (mass) per unit volume of a substance.
