Metric Conversions for TEAS 7 Questions
Question 1 of 5
What is the metric prefix for 10^-12 and how does it relate to meters?
Correct Answer: C
Rationale: The correct answer is C) femto- (f) = 10^-12 meters. In the metric system, prefixes indicate powers of 10 that are used to denote decimal multiples and submultiples of units. The prefix "femto-" represents 10^-15, not 10^-12. Therefore, option A and D are incorrect. The prefix "pico-" actually corresponds to 10^-12, making option A incorrect as well. Option B, "nano-" represents 10^-9, which is not the correct prefix for 10^-12. Educationally, understanding metric prefixes is crucial for accurate measurements and conversions in various fields such as science, engineering, and healthcare. It allows for easier manipulation of numbers and units in calculations. Knowing the correct prefix for a given power of 10 helps in expressing quantities in a more concise and standardized manner, enhancing communication and precision in scientific contexts.
Question 2 of 5
What is equivalent to 1 L?
Correct Answer: D
Rationale: 1 liter is equivalent to 1000 milliliters. This conversion is based on the fact that 1 liter equals 1000 milliliters, a standard metric relationship. Choice A is incorrect because a kilogram is a unit of mass, not volume. Choice B, 1 quart, is a non-metric unit of volume and is not equivalent to 1 liter. Choice C, 1 milliliter, is too small to be equivalent to 1 liter; it takes 1000 milliliters to make up 1 liter.
Question 3 of 5
The prefix giga is represented by the following notation ________.
Correct Answer: A
Rationale: The correct answer is A: 'G'. The prefix 'giga' is commonly represented by the letter 'G' and corresponds to a factor of 10^9, which is equivalent to one billion. Choice B, 'm', represents the prefix 'milli', which corresponds to a factor of 10^-3, not 'giga'. Choice C, 'Gg', is incorrect as the prefix 'giga' is represented by a single letter 'G', not 'Gg'. Choice D, 'g', is incorrect as it represents the prefix 'gram' in the International System of Units (SI) and not the prefix 'giga'.
Question 4 of 5
What is the equivalent of 1 nanometer (nm) in meters (m)?
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.
Question 5 of 5
What does 'kg' stand for in the metric system?
Correct Answer: A
Rationale: 'kg' stands for kilogram, the unit of mass equal to 1,000 grams. In the metric system, 'kg' specifically represents the unit of mass, making 'kilogram' the correct choice. The other choices, 'keg,' 'kroner,' and 'kraken,' do not represent the standard unit of mass in the metric system and are therefore incorrect.
