Physics

1. Laser light differs from typical light sources due to its properties of:

Correct answer: B

Rationale: The correct answer is B: Monochromatic nature (single color) and coherence (synchronized waves). Laser light is unique because it consists of a single color (monochromatic) and its waves are synchronized (coherent), unlike typical light sources which emit a range of colors and incoherent waves. This coherence allows laser light to stay focused over long distances, making it useful in various applications such as surgery, communication, and manufacturing. Enhanced brightness (A) is not the only distinguishing factor of laser light, as coherence and monochromatic nature are equally important. Increased velocity (C) and limited visibility to the human eye (D) are not properties that define laser light. Therefore, option B is the most accurate choice.

2. Which of the following is a characteristic of a solution with a high viscosity?

Correct answer: c

Rationale: Solutions with high viscosity have a high resistance to flow. The other choices do not accurately describe high viscosity.

3. The stratified cuboidal epithelium lining the salivary glands is responsible for:

Correct answer: C

Rationale: The correct answer is C: Secretion. The stratified cuboidal epithelium lining the salivary glands is specifically designed for the secretion of saliva, which plays a crucial role in the initial digestion of food. This type of epithelium has multiple layers of cells that provide protection and support for the glandular tissue underneath, allowing for the production and release of saliva. Options A, B, and D are incorrect as they do not accurately reflect the primary function of this particular epithelium. Therefore, the correct choice is C, secretion.

4. What is the main difference between a telescope and a microscope?

Correct answer: A

Rationale: While both instruments magnify objects, telescopes are designed to observe distant objects, while microscopes are used to magnify tiny objects close to the observer.

5. How can the periodic table be used to predict the charge of an ion formed by an element?

Correct answer: B

Rationale: Identify the group number, which corresponds to the typical ionic charge. Elements tend to gain or lose electrons to achieve a stable electron configuration like the noble gas group. Their group number often indicates the number of electrons gained/lost and the resulting ionic charge.

6. Based on the passage, which statement is MOST likely to be true about the author's stance on social media?

Correct answer: B

Rationale: The emphasis on critical thinking and responsible online behavior suggests an acknowledgment of social media's potential while advocating for addressing its downsides, aligning with B.
