ATI TEAS 7 science practice questions set 40

You review anatomy, chemistry, and scientific reasoning the way TEAS 7 reports the science line. Five of the 15 questions include the correct answer and rationale. The other ten keep answers in the study hub. Continue with the ATI TEAS 7 exam guide or more ATI TEAS 7 practice questions.

Five science questions with answers

Cover the key. Write the first action. Then open the rationale and name why the other choices fail.

Question 1

A ball is thrown upwards. Which of the following statements is TRUE about its potential energy and kinetic energy at the peak of its trajectory?

  1. A. Both potential and kinetic energy are zero.
  2. B. Potential energy is maximum and kinetic energy is minimum.
  3. C. Potential energy is minimum and kinetic energy is maximum.
  4. D. Both potential and kinetic energy remain constant.
Show answer and rationale

Correct answer: B — Potential energy is maximum and kinetic energy is minimum.

At the peak of its trajectory, the ball momentarily stops moving before falling back down. This means its kinetic energy is at a minimum because it has come to a stop. At the same time, its potential energy is at a maximum because it is at the highest point in its trajectory, where it has the most potential to fall and convert that potential energy into kinetic energy as it descends. Choice A is incorrect because at the peak, the ball still has potential energy due to its height. Choice C is incorrect because kinetic energy is at a minimum when the ball is momentarily at rest. Choice D is incorrect because the energy conversion between potential and kinetic energy occurs at different points in the trajectory.

Question 2

How does kinetic energy change when the velocity of an object is doubled?

  1. A. Kinetic energy is halved
  2. B. Kinetic energy quadruples
  3. C. Kinetic energy doubles
  4. D. Kinetic energy remains the same
Show answer and rationale

Correct answer: B — Kinetic energy quadruples

Kinetic energy is directly proportional to the square of the velocity of an object according to the kinetic energy formula (KE = 0.5 * m * v^2). When the velocity is doubled, the kinetic energy increases by a factor of 2^2 = 4. Therefore, the kinetic energy quadruples when the velocity of an object is doubled. Choice A is incorrect because halving the kinetic energy would be the result if the velocity was halved, not doubled. Choice C is incorrect because doubling the velocity would result in a fourfold increase in kinetic energy, not just a double. Choice D is incorrect because kinetic energy is directly related to the velocity of an object, so if the velocity changes, the kinetic energy changes accordingly.

Question 3

Two isotopes of the same element have different numbers of:

  1. A. Electrons
  2. B. Protons
  3. C. Neutrons
  4. D. Nuclei
Show answer and rationale

Correct answer: C — Neutrons

The correct answer is C: 'Neutrons.' Isotopes are variants of an element that have the same number of protons and electrons but differ in the number of neutrons they contain. This difference in neutron count is what distinguishes isotopes from each other while maintaining the same chemical properties. Choice A, 'Electrons,' is incorrect because isotopes of the same element have the same number of electrons. Choice B, 'Protons,' is incorrect because isotopes of the same element have the same number of protons. Choice D, 'Nuclei,' is incorrect as nuclei refer to the central part of an atom containing protons and neutrons, and the question specifically asks about differences between isotopes of the same element.

Question 4

What is the purpose of an electrocardiogram?

  1. A. Indicate the rate of blood flow
  2. B. Display the heart's rate and rhythm
  3. C. Identify a person's blood group type
  4. D. Determine cell type in a blood sample
Show answer and rationale

Correct answer: B — Display the heart's rate and rhythm

An electrocardiogram (ECG or EKG) is used to measure and display the heart's rate and rhythm. It provides valuable information about the electrical activity of the heart, allowing healthcare providers to assess the heart's health, detect abnormalities in the heart's rhythm, and diagnose various cardiac conditions. Choices A, C, and D are incorrect. Choice A is incorrect because an ECG does not indicate the rate of blood flow but rather focuses on the heart's electrical activity. Choice C is incorrect because identifying a person's blood group type is typically done through blood typing tests, not ECG. Choice D is incorrect because determining cell type in a blood sample is unrelated to the purpose of an ECG.

Question 5

What is the difference between a real image and a virtual image formed by a lens?

  1. A. Real images can be projected onto a screen, while virtual images cannot.
  2. B. Real images are always upright, while virtual images can be inverted.
  3. C. Real images are formed by converging lenses, while virtual images are formed by diverging lenses.
  4. D. All of the above are true.
Show answer and rationale

Correct answer: A — Real images can be projected onto a screen, while virtual images cannot.

The correct answer is A. Real images can be projected onto a screen because they are formed by the actual convergence of light rays, while virtual images cannot be projected onto a screen as they appear to diverge from a point behind the lens. Real and virtual images do not have a consistent orientation (upright or inverted), so option B is incorrect. Real images are formed by both converging and diverging lenses depending on the specific scenario, so option C is not a definitive distinction. Option D is incorrect as not all the statements are true. Therefore, the only accurate general distinction between real and virtual images is that real images can be projected onto a screen, while virtual images cannot.
