Physics

1. In nuclear transmutation, a target nucleus is bombarded with a particle to create:

Correct answer: C

Rationale: In nuclear transmutation, a target nucleus is bombarded with a particle to create an entirely new element. During this process, the target nucleus absorbs the incoming particle, resulting in changes to its atomic number and sometimes its mass number. These changes can lead to the creation of a different element altogether. This is a fundamental concept in nuclear chemistry and is used in various applications, including the creation of new isotopes for research or medical purposes. Options A and B are incorrect because transmutation involves creating a different element, not just a heavier or lighter isotope of the same element. Option D, a chain reaction of nuclear fission, is also incorrect as it refers to a different process where a nucleus splits into smaller fragments, releasing energy and more neutrons to sustain the chain reaction.

2. A water fountain has a spherical base (diameter 50cm) and a cylindrical body (diameter 30cm, height 80cm) on top. What is the total surface area of the fountain (excluding the water surface)?

Correct answer: C

Rationale: Calculate the surface area of the sphere and the cylinder separately, then add them up.

3. The author's tone towards UBI can be described as

Correct answer: D

Rationale: The passage acknowledges both positive and negative aspects of UBI, suggesting a cautious and balanced perspective, aligning with D.

4. What is the unit of measurement for momentum?

Correct answer: A

Rationale: Momentum is defined as the product of an object's mass and its velocity. The unit of mass is kilograms (kg) and the unit of velocity is meters per second (m/s). Therefore, the unit of momentum is kilogram-meter per second (kg·m/s). By Newton's second law of motion (F = ma), force is measured in Newtons (N), which is equivalent to kg·m/s². Therefore, multiplying the unit of force (N) by the unit of time (s) gives the unit of momentum as Newton-second (N·s).

5. The human eye focuses light by adjusting the shape of its:

Correct answer: C

Rationale: The human eye focuses light by adjusting the shape of its lens. The cornea is the transparent outer covering of the eye that helps to focus light, but it does not change shape. The iris regulates the amount of light entering the eye through the pupil but does not adjust the shape of the light. The retina is the layer at the back of the eye that receives and processes light signals but does not play a role in focusing light. Therefore, the correct answer is C, the lens, as it changes shape to focus light onto the retina, allowing for clear vision.

6. Identify the type of clause in the sentence "When the clock struck midnight, the magic began."

Correct answer: B

Rationale: The "when" clause introduces additional information about the main sentence and acts as a subordinate clause.
