Physics

1. An object is thrown upwards and reaches a maximum height. Which of the following statements is TRUE about its velocity and acceleration at the peak?

Correct answer: A

Rationale: At the peak, the object momentarily stops moving (zero velocity), but gravity still pulls it upwards, causing a maximum upward acceleration.

2. An element with atomic number 26 and mass number 56 is most likely to be:

Correct answer: A

Rationale: Iron (Fe) - Fe-56 has 26 protons and aligns with the given atomic number and mass number.

3. What is the process of breaking down and rebuilding bone tissue called?

Correct answer: B

Rationale: The correct answer is B: Remodeling. Remodeling is the process of breaking down and rebuilding bone tissue. This process helps maintain bone strength and structure by replacing old or damaged bone with new bone. Ossification refers to the formation of bone tissue, not the breakdown and rebuilding process. Calcification is the deposition of calcium salts in tissues, not specifically related to bone tissue remodeling. Osteoporosis is a condition characterized by a decrease in bone density, but it is not the process of breaking down and rebuilding bone tissue.

4. What type of sentence is the following: "Wow, what a beautiful sunset!"

Correct answer: C

Rationale: The sentence expresses an emotion ("Wow") and makes an exclamation, making it an exclamatory sentence.

5. Which group of elements is known for their reactivity and ability to form strong bonds with other elements?

Correct answer: B

Rationale: Rationale: Halogens are a group of elements in the periodic table that are known for their high reactivity and ability to form strong bonds with other elements. They have seven valence electrons, which makes them highly reactive as they only need one more electron to achieve a stable electron configuration. Halogens readily form compounds with other elements by gaining an electron to achieve a full outer shell, resulting in the formation of strong covalent bonds. In contrast, noble gases (option A) are known for their inertness and stable electron configurations, alkali metals (option C) are highly reactive but not as strong bond formers as halogens, and transition metals (option D) are known for their variable oxidation states and ability to form complex ions but are not as reactive as halogens in terms of bond formation.

6. Which phenomenon describes the separation of light into its component colors when passing through a prism?

Correct answer: c

Rationale: Dispersion occurs when light passes through a prism, causing different wavelengths (colors) to separate due to their varying speeds through the medium.
