physics

1. What property of matter refers to the force of gravity acting on an object?

Correct answer: b

Rationale: Weight is the measure of the force of gravity acting on an object. It is calculated as mass multiplied by the acceleration due to gravity.

2. According to the wave theory of light, the bright fringes observed in a double-slit experiment correspond to:

Correct answer: A

Rationale: The correct answer is A: Constructive interference. According to the wave theory of light, when two light waves meet in phase (crest to crest or trough to trough), they combine to produce a brighter fringe. This is known as constructive interference, leading to the formation of bright fringes in a double-slit experiment. Destructive interference, on the other hand, occurs when two waves are out of phase (crest to trough), resulting in a dimmer or dark fringe. Increased diffraction refers to the bending of light waves around obstacles, not the formation of bright fringes. Total internal reflection is a phenomenon that occurs at the boundary between two different mediums when light is reflected back into the original medium. Therefore, the bright fringes observed in a double-slit experiment correspond to constructive interference.

3. What part of speech is the underlined word in the sentence "I was disappointed by the outcome"?

Correct answer: C

Rationale: "Disappointed" modifies the pronoun "I," making it an adjective.

4. Identify the indirect object in the following sentence: "He gave his mother a bouquet of flowers."

Correct answer: A

Rationale: The indirect object tells who or what benefits from the action of the verb.

5. Lymph nodes, found along lymphatic vessels, are important for:

Correct answer: D

Rationale: The correct answer is D, 'All of the above.' Lymph nodes are important for various functions in the immune system. They filter lymph, trapping harmful substances like bacteria and viruses, which helps in preventing infections. Lymph nodes also play a crucial role in producing antibodies, which are essential for fighting off pathogens. Additionally, lymph nodes do not store blood; that is the function of the spleen. Therefore, the correct answer is D because lymph nodes perform all the mentioned functions in supporting the body's immune response.

6. A ball is thrown upwards. Which of the following statements is TRUE about its potential energy and kinetic energy at the peak of its trajectory?

Correct answer: B

Rationale: At the peak, the ball momentarily stops moving, minimizing kinetic energy. However, it's still at its highest point, maximizing its potential energy due to gravity.
