1. 10^6 m can be expressed as ____.

• A. 1 kilometer
• B. 1 megameter
• C. 1 gigameter
• D. 1 terameter

Correct answer: A

Rationale: The correct answer is A: 1 kilometer. 10^6 meters is equivalent to 1 kilometer, not 1 megameter. The prefix 'kilo-' represents a factor of 10^3 or one thousand, which is the appropriate conversion in this case. Choice B, 1 megameter, would be 10^6 meters squared. Choices C and D, 1 gigameter and 1 terameter, would represent even larger distances, as 'giga-' represents 10^9 and 'tera-' represents 10^12.

2. Is 0.25 mg equal to 250 mcg?

• A. TRUE
• B. FALSE
• C. Sometimes
• D. None of the above

Correct answer: A

Rationale: The correct answer is A: TRUE. 0.25 mg is indeed equal to 250 mcg. This conversion is obtained by multiplying 0.25 mg by 1000 to convert it to micrograms. In pharmaceuticals, it is crucial to understand and convert between different dosage units accurately. Choice B is incorrect as the two quantities are equivalent. Choice C, 'Sometimes,' is misleading as the conversion from milligrams to micrograms follows a consistent ratio. Choice D, 'None of the above,' is incorrect as there is a definitive equivalence between the provided quantities.

3. How many centimeters are in 1 meter?

• A. 10 cm
• B. 100 cm
• C. 1,000 cm
• D. 10,000 cm

Correct answer: B

Rationale: The correct answer is B: 100 cm. 1 meter is equivalent to 100 centimeters. Choice A (10 cm) is incorrect as it represents the conversion of decimeters to centimeters. Choice C (1,000 cm) is incorrect as it represents the conversion of meters to millimeters. Choice D (10,000 cm) is incorrect as it represents the conversion of meters to centimeters with an extra zero.

4. How many cups are in one pint?

• A. 1 cup
• B. 2 cups
• C. 3 cups
• D. 4 cups

Correct answer: B

Rationale: One pint is equivalent to 2 cups. This conversion is a common measurement in cooking and baking. Choice A (1 cup), Choice C (3 cups), and Choice D (4 cups) are incorrect because a pint specifically contains 2 cups according to standard measurement conversions.

5. What is the equivalent of 1 nanometer (nm) in meters (m)?

• A. 10^-9 meters
• B. 10^-6 meters
• C. 10^-12 meters
• D. 10^-15 meters

Correct answer: A

Rationale: The correct answer is A: 10^-9 meters. 1 nanometer (nm) is equivalent to 10^-9 meters. This conversion is commonly used in various scientific fields, including nanotechnology, to represent extremely small lengths. Choice B, 10^-6 meters, is incorrect as it represents a micrometer, not a nanometer. Choice C, 10^-12 meters, is incorrect as it would be a picometer, which is smaller than a nanometer. Choice D, 10^-15 meters, is incorrect as it would be a femtometer, much smaller than a nanometer.
