physics

1. What is the relationship between mass and weight on Earth's surface?

Correct answer: a

Rationale: On Earth's surface, mass and weight are directly proportional but not equal, as weight is the force due to gravity acting on an object's mass.

2. Which of the following is the primary function of the ovaries in the female reproductive system?

Correct answer: C

Rationale: The primary function of the ovaries in the female reproductive system is to produce eggs (ova). Ovaries are responsible for the production and release of eggs during the menstrual cycle, which can be fertilized by sperm to form a zygote. This process is essential for reproduction and the continuation of the species. Options A, B, and D are incorrect as transporting sperm to the uterus is the role of the fallopian tubes, producing milk for feeding offspring is the function of the mammary glands, and regulating urination is controlled by the bladder and associated muscles, not the ovaries.

3. When ice melts, it undergoes a…

Correct answer: B

Rationale: Melting is a change in physical state, not a change in the chemical composition of the ice.

4. What type of waves require a medium (solid, liquid, or gas) to propagate?

Correct answer: B

Rationale: Longitudinal waves require a medium (solid, liquid, or gas) to propagate because the particles in the medium move parallel to the direction of the wave. Transverse waves, on the other hand, do not require a medium and can propagate through a vacuum. Electromagnetic waves also do not require a medium for propagation, as they consist of oscillating electric and magnetic fields. Surface waves are a combination of both longitudinal and transverse waves and also require a medium to propagate.

5. What is the term for a solution with a pH value less than 7?

Correct answer: a

Rationale: Solutions with a pH less than 7 are acidic. The other choices do not accurately describe solutions with a pH less than 7.

6. What property of a substance remains constant regardless of changes in gravity?

Correct answer: A

Rationale: Mass is a measure of the amount of matter in an object and remains constant regardless of changes in gravity. Weight, on the other hand, is a measure of the gravitational force acting on an object and varies with changes in gravity. Volume is the amount of space occupied by an object and can change with changes in gravity. Density is the mass of a substance per unit volume and can also change with changes in gravity if the volume changes.
