ROUND 9: Science - The Coherence of Metric Measure

In both the SI and CGS versions of the metric system, many of the
units of measure can be expressed in terms of the multiplication
or division of other units of measure, with no numerical constants
other than 1 involved.  In each case, name the unit being expressed.

1. This unit measures the force needed to accelerate a 1 kilogram
   mass to a speed of 1 meter per second in 1 second.  That is,
   1 kilogram meter per second squared equals 1 of what unit?

	newton


2. Similarly in CGS metric, 1 gram centimeter per second squared
   equals 1 of what force unit?

	dyne


3. A force of 1 dyne exerted over a distance of 1 centimeter consumes
   how much energy, or equivalently, does how much work?  That is,
   1 dyne times 1 centimeter, or simply 1 dyne centimeter, equals
   1 of what energy unit?

	erg


4. And correspondingly in SI, 1 newton meter equals 1 of what energy unit?

	joule


5. This unit of power, or the rate of energy consumption, is equal to
   1 joule divided by 1 second; that is, it's 1 joule per second.

	watt


6. And which two commonly used electrical units can be multiplied
   together to produce 1 watt?

	ampere (accept "amp"), volt


7. So 1 volt times 1 ampere is 1 watt.  Now, 1 volt _divided_ by 1 ampere
   equals 1 of which resistance unit?

	ohm


8. The amount of charge delivered by a 1 ampere current flowing for
   1 second, or in other words 1 ampere times 1 second, equals 1 of
   what charge unit?

	coulomb


9. 1 coulomb divided by 1 volt equals 1 of which unit of capacitance?

	farad


10. Finally, this frequency unit is simply the reciprocal of 1 second.

	hertz
