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. Which nitrogenous bases pair with each other in DNA?

Correct answer: B

Rationale: Rationale: In DNA, nitrogenous bases pair with each other in a specific manner known as complementary base pairing. Adenine (A) always pairs with Thymine (T), and Cytosine (C) always pairs with Guanine (G). This pairing is essential for maintaining the structure and function of DNA. Therefore, option B is the correct answer as it correctly identifies the nitrogenous bases that pair with each other in DNA.

3. Which word best synonyms with the word "elated"?

Correct answer: C

Rationale: "Elated" and "excited" both convey feelings of happiness and enthusiasm.

4. hich word is most closely associated with the adjective "meticulous"?

Rationale: "Meticulous" implies carefulness and attention to detail, making "precise" its closest synonym.

5. A light ray travels from air (refractive index 1.00) into water (refractive index 1.33). What happens to its speed and direction?

Correct answer: A

Rationale: Due to the change in refractive index, the light ray bends towards the normal (water) as it slows down upon entering the denser medium.

6. Which type of waves do not require a medium for propagation?

Correct answer: c

Rationale: Electromagnetic waves (such as light or radio waves) can travel through a vacuum as they do not require a medium.
