TEAS Physics: Key Concepts for Exam Success

ATI TEAS 7

physics

1. Which of the following is a unit of work and energy?

A. Pascal (Pa)
B. Kilowatt-hour (kWh)
C. Coulomb (C)
D. Tesla (T)

Correct answer: b

Rationale: Kilowatt-hour is a unit used to measure both work and energy, especially in the context of electricity consumption.

2. Which phase of the employment process includes getting on the payroll and completing

A. Orientation
B. Induction
C. Selection
D. Recruitment

Correct answer: D

Rationale: The correct answer is D: Recruitment. Recruitment is the phase of the employment process where organizations actively seek out and attract potential candidates for job openings. This involves advertising the position, sourcing candidates, and conducting initial screenings. Once the recruitment process is complete and a candidate has been selected, they move on to the selection phase. Orientation, on the other hand, occurs after a candidate has been hired and involves familiarizing the new employee with the organization, its policies, and their role. Induction is often used interchangeably with orientation and refers to the process of integrating a new employee into the organization. Therefore, in this context, recruitment is the most appropriate phase that involves getting on the payroll and completing the initial steps to bring a new employee on board.

3. You test a new fertilizer on two groups of plants, one with fertilizer and one without. Both groups grow at the same rate. What is the most likely explanation?

A. The fertilizer has no effect on plant growth.
B. The control group accidentally received some fertilizer too.
C. Both groups received other nutrients from the soil, negating the fertilizer's effect.
D. The test period was too short to observe any difference.

Correct answer: C

Rationale: A true control group should be identical to the test group except for the variable being tested. If both groups grew the same despite the fertilizer, it suggests external factors like soil nutrients masked any potential fertilizer effect.

4. A solution is formed when:

A. One substance dissolves in another
B. Two or more substances react chemically
C. A solid changes to a liquid
D. None of the above

Correct answer: A

Rationale: One substance dissolves in another. A solution is a homogeneous mixture where one substance (solute) dissolves in another (solvent).

5. Nuclear binding energy represents the energy required to:

A. Separate an electron from its atom
B. Separate protons and neutrons within a nucleus
C. Cause nuclear fission
D. Induce nuclear fusion

Correct answer: B

Rationale: Nuclear binding energy is the energy required to hold the protons and neutrons within a nucleus together. This energy is necessary to overcome the electrostatic repulsion between positively charged protons in the nucleus. Option A, separating an electron from its atom, is related to ionization energy, not nuclear binding energy. Option C, causing nuclear fission, involves splitting a heavy nucleus into smaller nuclei, releasing energy but not directly related to the binding energy. Option D, inducing nuclear fusion, involves combining two light nuclei to form a heavier nucleus, also not directly related to the energy required to hold protons and neutrons together within a nucleus.
