Question 1 of 5
Which element is used in jewelry due to its malleability and resistance to tarnish?
Correct Answer: C
Rationale: Gold (C) is the correct answer because it is highly malleable and does not tarnish. Gold is a popular choice for jewelry due to its durability and resistance to corrosion. Iron (A) is not commonly used in jewelry due to its susceptibility to rust. Copper (B) is malleable but prone to tarnishing. Silver (D) is malleable but can tarnish over time, making it less ideal for long-lasting jewelry pieces.
Question 2 of 5
The spleen, a large lymphatic organ, is located in the:
Correct Answer: B
Rationale: The correct answer is B: Abdomen. The spleen is a large lymphatic organ located in the upper left quadrant of the abdomen, below the diaphragm and behind the stomach. Its main function is to filter blood, store blood cells, and assist in immune response. The other choices (A: Chest, C: Pelvis, D: Head and neck) are incorrect because the spleen is not located in these areas anatomically. The spleen's specific location in the abdomen is crucial for its functions and interactions with other organs in the abdominal cavity.
Question 3 of 5
Which vitamin is synthesized in the skin upon exposure to sunlight?
Correct Answer: C
Rationale: The correct answer is C: Vitamin D. When the skin is exposed to sunlight, a form of cholesterol in the skin is converted into Vitamin D. This vitamin plays a crucial role in calcium absorption and bone health. Vitamin A is not synthesized in the skin but obtained through diet. Vitamin C is obtained from fruits and vegetables. Vitamin E is a fat-soluble vitamin found in nuts and seeds. In summary, only Vitamin D is synthesized in the skin upon sunlight exposure, making it the correct answer.
Question 4 of 5
When sodium hydroxide (NaOH) reacts with hydrochloric acid (HCl), the resulting product is:
Correct Answer: A
Rationale: The correct answer is A: Hydrogen gas and sodium chloride (NaCl). When NaOH reacts with HCl, a neutralization reaction occurs, forming water and a salt. NaOH + HCl -> NaCl + H2O. Sodium chloride and water are the products formed in this reaction. Hydrogen gas is also produced as a byproduct. Choices B, C, and D are incorrect as they do not represent the correct products of the reaction based on the chemical equation.
Question 5 of 5
What is the main factor affecting the acceleration of a ball rolling down an inclined plane?
Correct Answer: B
Rationale: The correct answer is B: The angle of the incline. The acceleration of a ball rolling down an inclined plane is primarily determined by the angle of the incline. A steeper incline will result in a greater component of the gravitational force acting parallel to the incline, leading to a higher acceleration. The material of the ball (choice A) does not affect the acceleration in this scenario. Air resistance (choice C) may have a small impact but is usually negligible for small objects like balls. The ball's initial velocity (choice D) does not affect the acceleration once the ball is released from rest on the incline.
