1. What force keeps a car moving along a curved road?
- A. Gravitational force
- B. Normal force from the road
- C. Air resistance
- D. Friction between the tires and the road
Correct answer: D
Rationale: The correct answer is D: Friction between the tires and the road. When a car travels along a curved road, the friction between the tires of the car and the road provides the necessary centripetal force required to keep the car moving in the curved path. This friction allows the tires to grip the road and prevent the car from sliding off the curve due to inertia or momentum. Choices A, B, and C are incorrect because gravitational force, normal force from the road, and air resistance do not play a significant role in keeping a car moving along a curved road. While these forces may have other effects on the car's motion, they are not the primary force responsible for maintaining the car's trajectory along a curve.
2. Which of the following sentences uses the most formal language?
- A. The movie was awesome!
- B. The film did not meet my expectations.
- C. I found the cinematic experience to be unsatisfactory.
- D. The flick was pretty bad.
Correct answer: C
Rationale: Option C uses formal language by employing more sophisticated vocabulary ('cinematic experience') and refraining from informal terms like 'awesome' and 'flick.' Choice A ('awesome') and Choice D ('flick') use informal language typically used in casual contexts, making them less formal. Choice B, while more formal than Choices A and D, is still less formal than Choice C due to its less sophisticated vocabulary and directness in expressing dissatisfaction compared to the refined language used in Choice C.
3. Identify the determiner in the following sentence:
- A. happily
- B. branches
- C. few
- D. tree
Correct answer: C
Rationale: The determiner in the sentence is 'few.' Determiners specify the quantity or identity of a noun. In this case, 'few' indicates the number of birds present. Choice A, 'happily,' is an adverb modifying a verb or an adjective, not a determiner. Choice B, 'branches,' is a noun referring to parts of a tree, not a determiner. Choice D, 'tree,' is a noun identifying the main subject of the sentence, not a determiner.
4. Blood type is a trait determined by multiple alleles, with IA and IB being co-dominant: IA codes for A blood and IB codes for B blood, while i codes for O blood and is recessive to both. If an A heterozygote individual and an O individual have a child, what is the probability that the child will have A blood?
- A. 25%
- B. 50%
- C. 75%
- D. 100%
Correct answer: B
Rationale: If an A heterozygote (IAi) and an O individual (ii) have a child, there is a 50% chance the child will inherit the IA allele and have A blood. The A heterozygote can pass on either the IA or i allele, while the O individual can only pass on the i allele. Therefore, the possible genotypes for the child are IAi (A blood) or ii (O blood), resulting in a 50% chance of the child having A blood. Choice A (25%) is incorrect as it does not take into account the possibility of inheriting the IA allele. Choice C (75%) and Choice D (100%) are incorrect as they overestimate the probability of the child having A blood.
5. When is work done by a force on an object?
- A. Only when the object moves in the direction of the force
- B. Only when the object moves against the force
- C. Only when the object moves vertically
- D. Only when the force is applied for a specific duration
Correct answer: A
Rationale: Work is done by a force on an object when the object moves in the direction of the force. This is because work is defined as the product of the force applied to an object and the distance over which the force is applied. When the object moves in the direction of the force, the force contributes to the displacement of the object, resulting in work being done. If the object moves perpendicular to the force, no work is done because the force does not contribute to the displacement. Moving against the force also results in work being done as the force is causing the displacement. The vertical movement of the object does not determine whether work is done; it is the alignment of the force with the object's displacement that matters. The duration of force application does not impact whether work is done; as long as the force causes the object to move in its direction, work is being done.
