Make a graph of ln(V
⁄
V
0
) versus t.
a)
Press
to return to the Home Screen; press
to open the Graph
display.
b)
Press
to open the Graphs menu; press
to select New Graph
Page.
c)
Press
twice to highlight the data source menu. Select ln(v/v0) from
the menu
4.
Apply a linear fit and find the value of
τ
.
a)
Press
to open the Tools menu; press
to select Linear Fit.
b)
Press the down arrow key to make the dashed box surround the entire
data set.
c)
The slope of the best-fit line equals
τ
.
τ
= _________________ (include units)
5.
