physics

1. What is the relationship between work, force, and displacement?

Correct answer: b

Rationale: Work done is the product of force and displacement in the direction of the force.

2. 1. An object is initially at rest. Which of the following will definitely NOT cause it to move?

Correct answer: B

Rationale: No force acting on it. According to Newton's first law of motion, an object at rest will stay at rest unless acted upon by a net force.

3. Which of the following is the neutral subatomic particle found in the nucleus of an atom?

Correct answer: C

Rationale: Neutrons are subatomic particles found in the nucleus of an atom that have no charge. They have a mass of approximately 1 atomic mass unit (amu). The number of neutrons in an atom's nucleus contributes to the mass number of the atom, which is the total number of protons and neutrons in the nucleus.

4. Which of the following is NOT a source of genetic variation in a population?

Correct answer: D

Rationale: Rationale: A) Mutations in genes: Mutations are changes in the DNA sequence that can introduce new alleles into a population, leading to genetic variation. B) Genetic drift (random fluctuations in allele frequencies): Genetic drift refers to random changes in allele frequencies in a population, which can lead to genetic variation through chance events. C) Gene flow (movement of genes between populations): Gene flow occurs when individuals move between populations, bringing new alleles with them and increasing genetic variation within populations. D) Blending inheritance (traits of parents are averaged in offspring): Blending inheritance was a historical theory that suggested offspring inherit a blend of traits from their parents, leading to a reduction in genetic variation over time. However, this concept has been disproven by the understanding of Mendelian genetics, where traits are inherited independently and do not blend together. Therefore, blending inheritance does not contribute

5. Which property of a substance describes its ability to conduct heat or electricity?

Correct answer: b

Rationale: Conductivity refers to a substance's ability to conduct heat or electricity

6. The professor explained the concept clearly. What is the past participle of the verb "explain"?

Correct answer: C

Rationale: The past participle is used to form verb tenses and passive voice constructions.
