The names and locations (countries only) -- not e-mail addresses -- of quiz-takers, who successfully answer all questions correctly, will be displayed on the MMiQ Winners page for a period of six months -- with their permission. The winners' names will be published the day after the last day of the quizlet's six-month run (i.e., July 1 and January 1). If you prefer not to have your information displayed, then please indicate so in the form below.

If you enjoy these exercises, and know of others that may enjoy them as well, then please let them know by visiting the Tell A Friend page.

Quizlet Theme: SI Compound, or Derived, Units

INTRODUCTION
A measurement result consists of two things: a number and a unit. Units are defined in terms of physical standards. Standards come in many sizes and shapes, and some are better than others. All standards, however, are related through measurements to seven International System (SI) primary standards.

DEFINITION Compound, or derived, units are units for all quantities other than the seven SI base units of length, time, mass, electric current, temperature, luminous intensity, and amount of substance. In the International System (SI), all such units can be expressed as a combination of some of the base units.

Although compound units themselves have no primary standards, the units that compose them do. The SI unit for speed, for instance, is the metre per second. There is one primary standard for the metre, and another one for the second. Used together, they give us the standard for the metre per second. So no matter what measurement we make, we are always indirectly working our way back to comparisons with the primary SI standards.

INSTRUCTIONS
Given the SI derived unit's Quantity and Symbol, the following exercises require you to report its corresponding Name.

For example, the Name associated with force (Quantity), symbolized by N, is newton. You would report the name newton.

 

For all MMiQ Exercises, the accepted rules and conventions apply for: a) accuracy; b) precision; c) addition, subtraction, multiplication, and division of measurements; d) significant digit rule; and e) rounding (when applicable). If you don't know what they are, then please visit our brief Measurement Tutorial page for the explanations.

Don't forget that answers without accompanying UNITS will be considered incorrect (when applicable)!

Exercise 1-1: What is the Name that the following Quantity and Symbol describe?

Quantity: power, radiant flux
Symbol: W

Solution: The SI unit of power is one joule per second (1 J/s), which is called one watt (1 W).

Breakdown to primary SI standards:
The second in joule per second is the base unit for time.

A joule, J, can be converted to primary standards as follows:
1 J = 1 newton x 1 meter = 1 N x 1 m; the meter being the base unit of length.

1 N = mass x acceleration
      = 1 kilogram (the primary standard for mass) x 1 meter per square second
      = 1 kg x 1 m/s2

 

Exercise 1-2: What is the Name that the following Quantity and Symbol describe?

Quantity: inductance
Symbol: H

Solution: The SI unit of inductance is one weber per ampere (1 Wb/A), which is called one henry (1 H).

A weber, W, can be converted to primary standards as follows:

1 Wb = 1 volt-second per ampere = 1 Vs/A; the ampere being the base unit of electric current.

1 V = 1 joule per coulomb = 1 J/C

1 C = 1 ampere X second = 1 As

In conclusion, in the International System (SI), all compound, or derived, units can be expressed as a combination of some of the base units.
