TEAS Test 7 science Questions

Question 1 of 5

When two cars with different masses collide head-on, which car experiences a greater change in momentum?

Correct Answer: C

Rationale: In a head-on collision between two cars, the law of conservation of momentum states that the total momentum of the isolated system remains constant before and after the collision. The change in momentum of one car is equal in magnitude but opposite in direction to the change in momentum of the other car. As a result, both cars experience the same change in momentum during the collision. Choice A is incorrect because the change in momentum is the same for both cars due to the conservation of momentum principle. Choice B is incorrect as the smaller mass car does not experience a greater change in momentum. Choice D is incorrect as the initial velocities of the cars do not determine which car experiences a greater change in momentum; it is solely dependent on the masses of the colliding cars.

Question 2 of 5

What is the term for the energy absorbed during a chemical reaction?

Correct Answer: D

Rationale: The correct term for the energy absorbed during a chemical reaction is 'Endothermic energy.' Endothermic reactions absorb energy from their surroundings, leading to a decrease in temperature. The prefix 'endo-' means 'inward' or 'within,' indicating that energy is taken in during the reaction. Choices A, B, and C are incorrect because kinetic energy refers to the energy of motion, potential energy is stored energy, and heat energy is a form of energy transfer rather than specifically the energy absorbed during a chemical reaction.

Question 3 of 5

The small intestine is where most of the chemical digestion and nutrient absorption occur. What is the finger-like projection in the small intestine that increases its surface area for absorption?

Correct Answer: C

Rationale: Microvilli are the finger-like projections in the small intestine that increase its surface area for absorption. Villi are also present in the small intestine and help increase the surface area for absorption. However, microvilli are smaller structures found on the surface of villi, further increasing the surface area available for nutrient absorption. Rugae are folds in the stomach that allow for expansion when food is consumed and are not found in the small intestine. Therefore, the correct answer is C) Microvilli. Villi and microvilli are specific to the small intestine, playing vital roles in nutrient absorption, while rugae are specific to the stomach's structure and function, serving a different purpose than increasing surface area for absorption.

Question 4 of 5

Which type of energy is possessed by an object due to its position or configuration?

Correct Answer: C

Rationale: Potential energy is the energy that an object possesses due to its position or configuration. It is considered stored energy that can be converted into other forms of energy to do work. When an object is lifted against gravity or compressed, it gains potential energy. Kinetic energy, the incorrect choice A, is the energy of motion possessed by an object. Thermal energy, the incorrect choice B, is related to the temperature of an object due to the motion of its particles. Electrical energy, the incorrect choice D, is related to the flow of electric charge in a circuit or system. Therefore, the correct answer is potential energy as it is associated with an object's position or configuration.

Question 5 of 5

Which type of waves exhibit both longitudinal and transverse motion?

Correct Answer: B

Rationale: Surface waves exhibit both longitudinal and transverse motion. These waves travel along the boundary between two different mediums, such as water and air, causing particles to move both parallel (longitudinal) and perpendicular (transverse) to the wave's direction of travel. This unique characteristic distinguishes surface waves from other types of waves, making them the correct answer in this context. Electromagnetic waves, like light and radio waves, are purely transverse in nature, propagating through vacuum or different media through oscillating electric and magnetic fields perpendicular to the direction of wave travel. Mechanical waves, including both transverse (e.g., water waves) and longitudinal (e.g., sound waves in air) waves, do not typically exhibit both types of motion simultaneously, unlike surface waves.
