1.
Give the dimensions and units for the two following examples using the
background material below:
a.
DENSITY
=
MASS / VOLUME
Dimensions (volume
basic units) = _________________________________
Metric (SI) units =
________________________________________________
b.
VOLUME of WATER FLOWING = VOLUME
/
TIME
Dimension (basic units) = ___________________________________________
Metric (SI) units = _________________________________________________
2.
Convert the following to standard form:
a.
.0000000567 = ______________________ Sig. figs?
____________
b.
.0001460 = _________________________ Sig. figs?
____________
c.
3250076 = _________________________
Sig. figs?
____________
3.
Reexpress this number in exponential form with 3 sig. figs.
3467219
________________________
4.
Use the table on the third page.
a.
Round off each value in Column 2 to three significant digits (or 3 sig figs) and put
the new values in Column 6 [rounded e
x
].
b.
For each x in Column 1, compute x
4
and put them in Column 5 of the table.
c.
Look at the data in Column 6 and Column 2.
Has rounding off the numbers made
the numbers
more
or
less
difficult to use in other calculations?
________
Has the rounding process changed the values very much? ____________________

Plotting
5.
Use graph paper.
Use the horizontal axis for x and the vertical axis for x2, x
3
, x
4
, etc.
.
Use the short side of the graph paper for the horizontal (x) and the long side for the
vertical.
Use 100 units per cm on the vertical and label it every 200.
Use 0.5 units per cm on the horizontal and label it every 1.
