Physics

1. What is the work done by a force of 20 N acting on an object that moves 5 meters in the direction of the force?

Correct answer: A

Rationale: Work is defined as the force applied multiplied by the distance moved in the direction of the force. Work = force x distance = 20 N x 5 m = 100 J.

2. Which group of elements are known for their vibrant colors and use in fireworks?

Correct answer: D

Rationale: Transition metals exhibit diverse electronic configurations, leading to their ability to emit specific colors of light, making them ideal for fireworks.

3. What is the momentum of a car with a mass of 1500 kg moving at a speed of 20 m/s?

Correct answer: A

Rationale: Momentum is defined as the product of mass and velocity. Momentum = mass x velocity = 1500 kg x 20 m/s = 30,000 kg m/s.

4. What is the muscular sac in the female body that nourishes and protects a developing fetus?

Correct answer: C

Rationale: The correct answer is C: Uterus. The uterus is a muscular sac in the female body where a fertilized egg implants and develops into a fetus during pregnancy. It provides nourishment to the developing fetus and protects it throughout gestation. The ovaries produce eggs, the fallopian tubes transport eggs from the ovaries to the uterus, and the vagina is the canal leading from the uterus to the outside of the body. Therefore, the uterus is the specific organ responsible for nourishing and protecting a developing fetus in the female body.

5. Semen, the fluid that carries sperm, is produced by which of the following structures in the male reproductive system?

Correct answer: D

Rationale: The correct answer is D: Seminal vesicles. Semen is a mixture of fluids produced by various structures in the male reproductive system. The seminal vesicles are responsible for producing a significant portion of the fluid in semen, which provides nutrients and protection for sperm. The testes produce sperm, but the fluid that carries sperm, known as semen, is primarily produced by the seminal vesicles. The scrotum is the external sac that houses the testes, and the prostate gland also contributes to semen production, but the seminal vesicles play a key role in producing the fluid that carries sperm.

6. What is the protective fluid that surrounds the brain and spinal cord?

Correct answer: B

Rationale: The correct answer is B: Cerebrospinal fluid. This fluid acts as a cushion for the brain and spinal cord, providing protection from impacts. Blood is essential for transporting nutrients and oxygen, but it does not directly surround or protect these vital nervous system structures. Myelin sheath is a fatty substance that insulates nerve fibers, not the fluid surrounding the nervous system. Insulin is a hormone involved in regulating blood sugar levels and is not related to protecting the brain and spinal cord.
