1. Which property of a wave represents the distance between two successive identical points on a wave?
- A. Wavelength
- B. Amplitude
- C. Frequency
- D. Period
Correct answer: a
Rationale: Wavelength is the distance between two identical points (like crests or troughs) on a wave.
2. The phrase "massive open online courses" (MOOCs) refers to
- A. Online learning platforms designed specifically for students with disabilities.
- B. University-level courses freely available to anyone with an internet connection.
- C. Interactive training modules aimed at developing job-specific skills and knowledge.
- D. Online resources offering personalized learning experiences tailored to individual needs.
Correct answer: B
Rationale: MOOCs by definition are open and accessible courses, aligning with B.
3. What is the half-life of a radioactive isotope, and how does it relate to its decay rate?
- A. The time it takes for half of the initial sample to decay.
- B. The time it takes for all the sample to decay.
- C. The rate at which new isotopes are created.
- D. The energy released during decay.
Correct answer: A
Rationale: Half-life tells the time it takes for half of the original radioactive nuclei to decay, offering an indication of the decay rate.
4. What is the term for a group of organisms with the same genetic makeup?
- A. Population
- B. Clone
- C. Genotype
- D. Species
Correct answer: B
Rationale: Rationale: - A population (option A) refers to a group of individuals of the same species living in the same area. - Genotype (option C) refers to the genetic makeup of an individual organism. - Species (option D) refers to a group of organisms that can interbreed and produce fertile offspring. In this context, a clone (option B) is a group of organisms that are genetically identical because they are derived from a single ancestor. This term specifically refers to organisms with the same genetic makeup, making it the most appropriate choice for the question.
5. A nurse needs to administer 0.8 milliliters of medication. The only available syringe measures in teaspoons. How many teaspoons should the nurse use?
- A. 0.2 teaspoons
- B. 0.4 teaspoons
- C. 0.6 teaspoons
- D. 0.8 teaspoons
Correct answer: B
Rationale: Rationale: 1 milliliter is equivalent to approximately 0.2 teaspoons. Therefore, to find out how many teaspoons are in 0.8 milliliters, we can set up a proportion: 0.8 milliliters * 0.2 teaspoons/1 milliliter = 0.16 teaspoons Since 0.16 teaspoons is not one of the answer choices, we need to convert it to a more practical measurement. The closest option is 0.4 teaspoons, which is the correct answer.
6. Define work in physics.
- A. Force applied to an object at rest
- B. Force exerted by an object in motion
- C. Transfer of energy through motion along a direction
- D. Measure of an object's potential energy
Correct answer: c
Rationale: Work in physics is the transfer of energy when a force is applied and the object moves in the direction of the force.
