physics

1. What happens to the acceleration of an object when the force acting on it is increased, assuming the mass remains constant?

Correct answer: a

Rationale: According to Newton's second law (F = ma), if mass is constant and force increases, acceleration also increases.

2. An ancient Egyptian pyramid has a square base with side lengths of 20 meters and a remaining height (after erosion) of 10 meters. Its original height was 30 meters. What was the volume of the pyramid in its original state?

Correct answer: A

Rationale: Use the formula for the volume of a pyramid with the original height and base area.

3. Which property of a wave determines its pitch in sound waves?

Correct answer: B

Rationale: The pitch of a sound wave is determined by its frequency. Frequency refers to the number of cycles of a wave that occur in a unit of time, usually measured in hertz (Hz). Higher frequencies correspond to higher pitches, while lower frequencies correspond to lower pitches. Amplitude refers to the height of a wave and is related to the loudness of the sound. Wavelength is the distance between two consecutive points in a wave that are in phase, and speed is the rate at which a wave travels through a medium.

4. In the reaction 2Na + 2H2O → 2NaOH + H2, what is the limiting reactant when 3 moles of sodium react with 2 moles of water?

Correct answer: a

Rationale: Sodium is the limiting reactant because it runs out first in a 1:1 ratio with water.

5. What property of a wave is responsible for determining its energy?

Correct answer: a

Rationale: The amplitude of a wave determines its energy, with higher amplitudes corresponding to higher energy levels.

6. Adipose tissue, commonly known as fat, primarily functions in:

Correct answer: D

Rationale: The correct answer is D, 'All of the above.' Adipose tissue, or fat, serves multiple functions in the body. It provides support by cushioning and protecting organs, acts as an insulation layer to maintain body temperature, and serves as a crucial energy storage site where excess energy is stored in the form of triglycerides. Therefore, all of the options listed (support, insulation, and energy storage) are accurate functions of adipose tissue.
