1. What happens to the potential energy of an object as it falls freely near the Earth's surface?
- A. Potential energy decreases
- B. Potential energy increases
- C. Potential energy remains constant
- D. Potential energy becomes zero
Correct answer: a
Rationale: As an object falls freely, its potential energy due to gravity decreases as it gets closer to the Earth's surface.
2. What is the difference between alpha decay and beta decay?
- A. Both release the same type of particle.
- B. Alpha decay releases a helium nucleus, while beta decay releases an electron or positron.
- C. Alpha decay is more common than beta decay.
- D. They both convert one element into another, but in different ways.
Correct answer: B
Rationale: Alpha decay releases a helium nucleus (2 protons, 2 neutrons), while beta decay releases an electron or positron. - Both processes alter the atomic structure and change the element's identity.
3. What is the meaning of the phrase "to be on the same page"?
- A. To be physically close
- B. To agree or understand each other

5. Which of the following is a risk factor for developing kidney stones?
- A. Consuming a diet rich in fruits and vegetables
- B. Maintaining adequate hydration with water
- C. Having a family history of kidney stones
- D. Regularly engaging in moderate exercise
Correct answer: C
Rationale: Having a family history of kidney stones is a risk factor for developing them because genetics play a role in kidney stone formation. Individuals with a family history are more likely to inherit genetic factors that increase the likelihood of developing kidney stones. While consuming a diet rich in fruits and vegetables, maintaining adequate hydration with water, and regularly engaging in moderate exercise are generally healthy habits that can help prevent kidney stones, they are not direct risk factors for developing them. Therefore, option C, having a family history of kidney stones, is the correct answer.
6. What phenomenon occurs when light passes through a medium but does not change direction, such as when passing through a window?
- A. Diffraction
- B. Reflection
- C. Dispersion
- D. Transmission
Correct answer: d
Rationale: Transmission occurs when light passes through a medium without changing direction, as observed when light passes through a window.
