TEAS Physics: Key Concepts for Exam Success

ATI TEAS 7

physics

1. Define "friction" in terms of opposing motion.

A. A force that increases motion
B. A force that accelerates motion
C. A force that opposes motion
D. A force that creates motion

Correct answer: c

Rationale: Friction acts opposite to the direction of motion, resisting or slowing down the movement of objects.

2. What is the term for a genetic disorder caused by a mutation on the X chromosome?

A. Autosomal dominant disorder
B. Autosomal recessive disorder
C. Sex-linked recessive disorder
D. Sex-linked dominant disorder

Correct answer: C

Rationale: Rationale: - Autosomal dominant disorders (Option A) are caused by a mutation in one copy of a gene on one of the non-sex chromosomes (autosomes). These disorders do not specifically involve the X chromosome. - Autosomal recessive disorders (Option B) are caused by mutations in both copies of a gene on the autosomes. They are not directly related to mutations on the X chromosome. - Sex-linked dominant disorders (Option D) are rare and typically result in more severe symptoms in males because they only need one copy of the mutated gene on the X chromosome to express the disorder. This is not the term for a genetic disorder caused by a mutation on the X chromosome. - Sex-linked recessive disorders (Option C) are genetic disorders caused by mutations on the X chromosome. These disorders are more commonly seen in males because they have only one X chromosome, making them more susceptible to X-linked mutations. Females have two

3. What is the relationship between work and the displacement of an object?

A. Work depends only on the force applied, not displacement
B. Work is directly proportional to displacement
C. Work is inversely proportional to displacement
D. Work is unrelated to displacement

Correct answer:

Rationale: Work done is directly proportional to the displacement of an object in the direction of the force applied.

4. Describe the concept of inertia in terms of Newton's first law.

A. Objects in motion tend to remain in motion unless acted upon by an external force
B. Objects at rest tend to remain at rest unless acted upon by an external force
C. An object's resistance to a change in its state of motion
D. The force required to lift an object

Correct answer: c

Rationale: Inertia refers to an object's tendency to maintain its current state of motion (either at rest or in motion) unless acted upon by an external force.

5. Which statement BEST summarizes the author's perspective on bioremediation for plastic pollution?

A. It is the only viable solution to the problem and should be prioritized.
B. It is a promising approach but requires further research and development.
C. It is less effective than traditional methods and poses environmental risks.
D. It is irrelevant to the problem and will not make a significant impact.

Correct answer: B

Rationale: The passage acknowledges the potential of bioremediation while highlighting the need for further research, indicating a balanced perspective.
