1. 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.

2. What is the formula to convert Celsius to Fahrenheit?

• A. (C × 9/5) + 32
• B. (C × 5/9) + 32
• C. (F × 9/5) - 32
• D. (F × 5/9) - 32

Correct answer: A

Rationale: The correct formula to convert Celsius to Fahrenheit is (C × 9/5) + 32. This formula involves multiplying the Celsius temperature by 9/5 and then adding 32 to get the Fahrenheit temperature. Choice B is incorrect as it suggests dividing by 5/9 instead of multiplying by 9/5. Choices C and D are both incorrect because they involve using the Fahrenheit temperature in the calculation, which is not the correct method for converting Celsius to Fahrenheit.

3. Convert 0.29 pounds to ounces.

• A. 2.9 ounces
• B. 4.64 ounces
• C. 29 ounces
• D. 46.4 ounces

Correct answer: B

Rationale: To convert pounds to ounces, you need to know that there are 16 ounces in a pound. Multiplying 0.29 pounds by 16 gives you 4.64 ounces. Therefore, the correct answer is B. Choice A (2.9 ounces) is incorrect as it doesn't consider the conversion factor of 16 ounces per pound. Choice C (29 ounces) and Choice D (46.4 ounces) are incorrect because they incorrectly interpret the conversion from pounds to ounces.

4. What is 0.45 liters in milliliters?

• A. 450 ml
• B. 45 ml
• C. 4.5 ml
• D. 0.45 ml

Correct answer: A

Rationale: To convert liters to milliliters, you need to multiply by 1000 since 1 liter equals 1000 milliliters. Therefore, 0.45 liters is equivalent to 450 milliliters. Choice B, 45 ml, is incorrect as it represents the conversion of 0.045 liters to milliliters. Choice C, 4.5 ml, is incorrect as it represents the conversion of 0.0045 liters to milliliters. Choice D, 0.45 ml, is incorrect as it is the initial quantity in milliliters and not the result of the conversion.

5. What does the prefix 'Tera' refer to?

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

Correct answer: A

Rationale: The prefix 'Tera' corresponds to a factor of 10^12, which is equivalent to one trillion. It is commonly used in various fields like data storage to denote large quantities. Choice B, '10^9,' is incorrect as it corresponds to the prefix 'Giga.' Choice C, '10^15,' is incorrect as it corresponds to the prefix 'Peta.' Choice D, '10^6,' is incorrect as it corresponds to the prefix 'Mega.' Therefore, the correct answer is A.
