Physics

1. What is the name of the radioactive isotope commonly used in medical imaging techniques like PET scans?

Correct answer: D

Rationale: Fluorine-18 is the radioactive isotope commonly used in medical imaging techniques like PET scans. It is often used in the form of fluorodeoxyglucose (FDG) to detect areas of increased metabolic activity in the body, such as in cancer cells. Uranium-235 and Plutonium-239 are not typically used in medical imaging, and Potassium-40 is a naturally occurring radioactive isotope found in the human body but is not commonly used in medical imaging techniques.

2. Which vitamin requires the lymphatic system for proper absorption from the intestine?

Correct answer: D

Rationale: The correct answer is D, Vitamin B12. Vitamin B12 requires the presence of intrinsic factor, a protein produced by the stomach, for absorption in the small intestine. This complex is then absorbed in the ileum with the help of the intrinsic factor. The absorption of Vitamin B12 is a unique process that relies on the function of the lymphatic system to transport it throughout the body. Vitamins A, C, and D are absorbed through other mechanisms and do not require the lymphatic system for proper absorption.

3. What is the formula for calculating molarity?

Correct answer: a

Rationale: All of these choices are equivalent to the original formula. The symbol "n" represents the number of moles of solute, and the symbol "V" represents the volume of the solution in liters. The symbol "L" is an abbreviation for "liters," and "dm³" is an alternative way to represent liters.

4. A birdbath has a hemispherical bowl with a diameter of 30cm. What is its volume?

Correct answer: C

Rationale: Use half the formula for a sphere's volume: (2/3) * π * (radius)^3. Calculate the radius (15cm) and substitute: (2/3) * π * (15cm)^3 ≈ 2700 cu cm.

5. What is the stoichiometric coefficient of nitrogen (N2) in the balanced equation for the Haber process: N2 + 3H2 → 2NH3?

Correct answer: a

Rationale: The coefficient of N2 is 1 in the balanced equation

6. Which word best completes the sentence: "The scientist conducted the experiment with _____ precision."

Correct answer: C

Rationale: Option C emphasizes the absolute and complete accuracy of the experiment.
