1. What is the equivalent of 3.54 millimeters in meters (m)?

• A. 0.0354 m
• B. 0.00354 m
• C. 35.4 m
• D. 0.035 m

Correct answer: B

Rationale: To convert millimeters to meters, you need to divide by 1,000 since there are 1,000 millimeters in a meter. Therefore, 3.54 mm ÷ 1,000 = 0.00354 meters. Choice A (0.0354 m) is incorrect as it is 10 times the correct conversion. Choice C (35.4 m) is incorrect as it would be the equivalent of 35,400 millimeters. Choice D (0.035 m) is also incorrect as it is 100 times greater than the correct conversion.

2. What is the metric prefix for 10^-12 and how does it relate to meters?

• A. pico- (p) = 10^-12 meters
• B. nano- (n) = 10^-12 meters
• C. femto- (f) = 10^-12 meters
• D. pico- (p) = 10^-15 meters

Correct answer: C

Rationale: The prefix 'femto-' stands for 10^-15, making femtometer equal to 10^-15 meters. The incorrect choices are A and B because 'pico-' represents 10^-12 (picometer) and 'nano-' represents 10^-9 (nanometer), respectively. Choice D is also incorrect as 'pico-' is associated with 10^-12, not 10^-15.

3. What does 'cm' stand for in the metric system?

• A. centimeter
• B. cubic meter
• C. cord
• D. centi

Correct answer: A

Rationale: In the metric system, 'cm' stands for centimeter, which is a unit of length equal to 1/100th of a meter. The correct answer is 'centimeter' (A). Choice B, 'cubic meter,' is a unit of volume, not length. Choice C, 'cord,' is not a standard metric unit. Choice D, 'centi,' is a prefix meaning one-hundredth, but 'cm' specifically stands for centimeter, not just the prefix.

4. Convert 35.40 kilograms to grams (g).

• A. 354 g
• B. 35,400 g
• C. 3,540 g
• D. 3.54 g

Correct answer: B

Rationale: To convert kilograms to grams, you need to multiply by 1,000 since there are 1,000 grams in a kilogram. Therefore, 35.40 kg × 1,000 = 35,400 grams. Choice A (354 g) is incorrect because it is off by a factor of 10. Choice C (3,540 g) is incorrect as it is off by a factor of 100. Choice D (3.54 g) is incorrect as it represents kilograms instead of grams.

5. What is 0.5 liters in milliliters?

• A. 50 ml
• B. 500 ml
• C. 5 ml
• D. 0.5 ml

Correct answer: B

Rationale: 0.5 liters is equivalent to 500 milliliters. To convert liters to milliliters, you multiply by 1000 since 1 liter equals 1000 milliliters. Therefore, the correct answer is 500 ml (0.5 * 1000 = 500). Choices A, C, and D are incorrect because they do not correctly convert 0.5 liters to milliliters.
