Responses to Questions
l l l




1. (a) A particular person’s foot. Merits: reproducible. Drawbacks: not accessible to the general
l l l l l l l l l l l l



public; not invariable (could change size with age, time of day, etc.); not indestructible.
l l l l l l l l l l l l l



(b) Any person’s foot. Merits: accessible. Drawbacks: not reproducible (different people havedifferent
l l l l l l l l l l l l



size feet); not invariable (could change size with age, time of day, etc.); not indestructible.
l l l l l l l l l l l l l l l



Neither of these options would make a good standard.
l l l l l l l l




2. The distance in miles is given to one significant figure, and the distance in kilometers is given to five
l l l l l l l l l l l l l l l l l l



significant figures! The value in kilometers indicates more precision than really exists or than is
l l l l l l l l l l l l l l l



meaningful. The last digit represents a distance on the same order of magnitude as a car’s length! The
l l l l l l l l l l l l l l l l l l



sign should perhaps read “7.0 mi (11 km),” where each value has the same number of significant
l l l l l l l l l l l l l l l l l



figures, or “7 mi (11 km),” where each value has about the same % uncertainty.
l l l l l l l l l l l l l l l




3. The number of digits you present in your answer should represent the precision with which you know a
l l l l l l l l l l l l l l l l l



measurement; it says very little about the accuracy of the measurement. For example, if youmeasure the
l l l l l l l l l l l l l l l l l



length of a table to great precision, but with a measuring instrument that is not calibrated correctly, you
l l l l l l l l l l l l l l l l l l



will not measure accurately. Accuracy is a measure of how close a measurement is to the true value.
l l l l l l l l l l l l l l l l l l




4. If you measure the length of an object and you report that it is “4,” you haven’t given enough
l l l l l l l l l l l l l l l l l l



information for your answer to be useful. There is a large difference between an object that is 4 meters
l l l l l l l l l l l l l l l l l l l



long and one that is 4 km long. Units are necessary to give meaning to a numerical answer.
l l l l l l l l l l l l l l l l l l




5. You should report a result of 8.32 cm. Your measurement had three significant figures. When you
l l l l l l l l l l l l l l l



multiply by 2, you are really multiplying by the integer 2, which is an exact value. The number of
l l l l l l l l l l l l l l l l l l l



significant figures is determined by the measurement.
l l l l l l l




6. The correct number of significant figures is three: sin 30.0º = 0.500.
l l l l l l l l l l l




7. Useful assumptions include the population of the city, the fraction of people who own cars, the average
l l l l l l l l l l l l l l l l



number of visits to a mechanic that each car makes in a year, the average number of weeks amechanic
l l l l l l l l l l l l l l l l l l l l



works in a year, and the average number of cars each mechanic can see in a week.
l l l l l l l l l l l l l l l l l



(a) There are about 800,000 people in San Francisco. Assume that half of them have cars. If each of
l l l l l l l l l l l l l l l l l



these 400,000 cars needs servicing twice a year, then there are 800,000 visits to mechanics in a year.
l l l l l l l l l l l l l l l l l l



If mechanics typically work 50 weeks a year, then about 16,000 cars would need to be seen each
l l l l l l l l l l l l l l l l l l



week. Assume that on average, a mechanic can work on 4 cars per day, or 20 cars a week. The final
l l l l l l l l l l l l l l l l l l l l l



estimate, then, is 800 car mechanics in San Francisco.
l l l l l l l l l



(b) Answers will vary. But following the same reasoning, the estimate is 1/1000 of the population. l l l l l l l l l l l l l l

Responses to MisConceptual Questions l l l




1. (c) As stated in the text, scientific laws are descriptive – they are meant to describe how nature behaves.
l l l l l l l l l l l l l l l l l l



Since our understanding of nature evolves, so do the laws of physics, when evidencecan convince
l l l l l l l l l l l l l l l l



the community of physicists. The laws of physics are not permanent, and are notsubject to
l l l l l l l l l l l l l l l l



political treaties. In fact, there have been major changes in the laws of physics since1900 –
l l l l l l l l l l l l l l l l l



particularly due to relativity and quantum mechanics. The laws of physics apply in chemistry and
l l l l l l l l l l l l l l l



other scientific fields, since those areas of study are based on physics. Finally, the laws of physics
l l l l l l l l l l l l l l l l l



are man-made, not a part of nature. They are our “best description” of nature as we currently
l l l l l l l l l l l l l l l l l



understand it. As stated in the text, “Laws are not lying there in nature, waiting to be discovered.”
l l l l l l l l l l l l l l l l l l




2. (e) The first product is 142.08 m, which is only accurate to the 10’s place, since 37 m/s has only two
lll l l l l l l l l l l l l l l l l l l l



significant figures. The second product is 74.73 m, which is only accurate to the 1’s place, since 5.3
l l l l l l l l l l l l l l l l l l



s has only two significant figures. Thus the sum of the two terms can only be accurateto the 10’s
l l l l l l l l l l l l l l l l l l l l



place. 142.08 + 74.73 = 216.81, which to the 10’s place is 220 m.
l l l l l l l l l l l l l l




3. (a) The total number of digits present does not determine the precision, as the leading zeros in (c) and (d)
l l l l l l l l l l l l l l l l l l l



are only place holders. Rewriting all the measurements in units of meters shows that (a)implies a
l l l l l l l l l l l l l l l l l



precision of 0.0001m, (b) and (c) both imply a precision of 0.001 m, and (d) implies aprecision of
l l l l l l l l l l l l l l l l l l l



0.01 m. Note that since the period is shown, the trailing zeros are significant. If allthe
l l l l l l l l l l l l l l l l l



measurements are expressed in meters, (a) has 4 significant figures, (b) and (c) each have 3
l l l l l l l l l l l l l l l l



significant figures, and (d) has 2 significant figures.
l l l l l l l l




4. (b) The leading zeros are not significant. Rewriting this number in scientific notation, 7.810−3 ,
l l l l l l l l l l l l l l
l




shows that it only has two significant digits.
l l l l l l l l




5. (b) When you add or subtract numbers, the final answer should contain no more decimal places than
l l l l l l l l l l l l l l l l



the number with the fewest decimal places. Since 25.2 has one decimal place, the answermust be
l l l l l l l l l l l l l l l l l



rounded to one decimal place, or to 26.6. Thus the answer has 3 significant figures.
l l l l l l l l l l l l l l l




6. (b) The word “accuracy” is often misused. If a student repeats a measurement multiple times and
l l l l l l l l l l l l l l l



obtains the same answer each time, it is often assumed to be accurate. In fact, students are
l l l l l l l l l l l l l l l l l



frequently given an “ideal” number of times to repeat the experiment for “accuracy.” However,
l l l l l l l l l l l l l l



systematic errors may cause each measurement to be inaccurate. A poorly working instrument
l l l l l l l l l l l l l



may also limit the accuracy of your measurement.
l l l l l l l l




7. (a) Quoting the textbook, “precision” refers to the repeatability of the measurement using a given
l l l l l l l l l l l l l l



instrument. Precision and accuracy are often confused. “Accuracy” is defined by answer (b).
l l l l l l l l l l l l l




8. (d) This addresses misconceptions about squared units and about which factor should be in the
l l l l l l l l l l l l l l



numerator of the conversion. This error can be avoided by treating the units as algebraic
l l l l l l l l l l l l l l l



symbols that must be cancelled out.
l l l l l l




9. (e) When making estimates, the estimator may frequently believe that their answers are more
l l l l l l l l l l l l l



significant than they actually are. This question helps the estimator realize what an order-of-
l l l l l l l l l l l l l l



magnitude estimation is NOT supposed to accomplish.
l l l l l l l




10. (d) This addresses the fact that the generic unit symbol, like [L], does not indicate a specific systemof
l l l l l l l l l l l l l l l l l l



units. l
