1. 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: The work done is calculated using the formula: Work = Force x Distance x cos(theta), where theta is the angle between the force and the direction of motion. In this case, the force and the direction of motion are in the same direction, so cos(theta) = 1. Therefore, Work = 20 N x 5 m x 1 = 100 Joules. Since the force and distance are given and are in the same direction, the work done can be directly calculated without needing to know the object's mass. Choice A, 100 Joules, is the correct answer as calculated. Choice B and C are incorrect as they do not correspond to the correct calculation. Choice D is incorrect because knowing the object's mass is not necessary to calculate work in this scenario, as work is dependent on force, distance, and the angle between them, not mass.

2. Which of the following would be the best concluding statement for this passage?

• A. States should consider the importance of foreign languages for the global economy when making policies regarding foreign language requirements for high school graduation.
• B. Policies for high school graduation should consider the significance of foreign languages for the global economy, college acceptance rates, and job opportunities.
• C. Influence of a second language on college acceptance rates warrants a foreign language class as a high school graduation requirement.
• D. The difficulty of obtaining a job in today’s economy without knowledge of multiple languages should be considered when setting foreign language requirements for high school graduation.

Correct answer: B

Rationale: Choice B provides the best concluding statement for this passage as it encapsulates the main argument and key supporting details presented in the extract. The passage emphasizes the importance of foreign languages for the global economy, the impact on college acceptance rates, and enhanced job opportunities for individuals proficient in more than one language. Choice B effectively summarizes these points, making it the most appropriate conclusion. Choices A, C, and D, while related to the main argument, only touch on one supporting detail each. Choice A focuses solely on the importance of foreign languages for the global economy, while choice C emphasizes the influence of a second language on college acceptance rates. Choice D highlights the difficulty of job acquisition without knowledge of multiple languages. These choices do not encompass the breadth of supporting details provided in the passage, making them less effective as concluding statements.

3. Four more than a number is 2 less than 5\6 of another number. Which equation represents this?

• A. x + 4 = 5\6y - 2
• B. x + 4 = 2 - 5\6y
• C. 4 + x = 5\6y + 2
• D. x + 4 = 5\6y - 2

Correct answer: A

Rationale: The equation that represents the relationship is x + 4 = 5\6y - 2.

4. According to the passages, which situation would not constitute an illegal use of lethal force?

• A. A disgruntled cashier yells obscenities at a customer.
• B. A thief is seen running away with stolen cash.
• C. A man is attacked in an alley by another man with a knife.
• D. A woman punches another woman in a bar.

Correct answer: C

Rationale: The correct answer is C because, according to the passage, lethal force may be legally used in self-defense or to protect others from imminent danger. In the situation where a man is attacked in an alley by another man with a knife, the use of lethal force to defend oneself would not constitute an illegal act. Choices A, B, and D do not involve a situation where the use of lethal force in self-defense would be justified, making them incorrect. A disgruntled cashier yelling obscenities, a thief running away with stolen cash, and a woman punching another woman do not present imminent danger that would justify the use of lethal force.

5. The van't Hoff factor (i) accounts for the number of particles a solute dissociates into in solution. For a compound that dissociates completely in water, i would be...

• A. 0
• B. Less than 1
• C. 1
• D. More than 1

Correct answer: D

Rationale: The van't Hoff factor (i) represents the number of particles a solute dissociates into in solution. For a compound that dissociates completely in water, i would be more than 1 because it breaks apart into more particles than the original compound. This is due to complete dissociation leading to an increase in the number of particles in solution, resulting in i being greater than 1. Choice A is incorrect as a compound that dissociates completely will not have an i value of 0. Choice B is incorrect because when a compound dissociates completely, the van't Hoff factor is not less than 1. Choice C is incorrect as a compound that dissociates completely will not have an i value of 1, but rather more than 1 due to the increased number of particles in solution.
