physics

1. How does the potential energy of an object change when it is compressed?

Correct answer: b

Rationale: When an object is compressed, it stores potential energy due to its altered position or configuration.

2. A study finds a link between increased screen time and lower academic performance. What additional information would be most helpful in interpreting this finding?

Correct answer: B

Rationale: Knowing the specific types of screen activities participants engaged in would provide crucial context for interpreting the link between increased screen time and lower academic performance. For example, if the majority of screen time was spent on educational apps or programs, the impact on academic performance may differ compared to if the screen time was mostly spent on social media or gaming. Understanding the nature of screen activities can help determine the potential mechanisms behind the observed relationship.

3. What happens when an atom loses an electron?

Correct answer: B

Rationale: It gains a positive charge and becomes an ion. Losing an electron disrupts the charge balance, leaving the atom with more protons than electrons and a positive charge.

4. Which of the following organs is responsible for churning and mechanically breaking down food?

Correct answer: C

Rationale: Rationale: The stomach is responsible for churning and mechanically breaking down food. It contains muscles that contract and relax to mix food with digestive juices, breaking it down into smaller particles. This mechanical digestion process helps prepare the food for further digestion and absorption in the small intestine. The small intestine is primarily responsible for the absorption of nutrients, the large intestine absorbs water and salts, the esophagus is a muscular tube that transports food from the mouth to the stomach.

5. What happens to the momentum of an object when there is no external force acting upon it?

Correct answer: c

Rationale: In the absence of external forces, momentum remains constant due to the conservation of momentum.

6. What is the absolute value of -7?

Correct answer: A

Rationale: Absolute value refers to the non-negative distance of a number from zero. Regardless of being positive or negative, 7 is its distance from zero.
