Transcribed Image Text:Two cylindrical cans with insulating sides and conducting end caps are
filled with water, attached to the circuitry shown in (Figure 1), and used
to determine salinity levels. The cans are identical, with radius
r = 5.00 cm and length L = 3.50 cm. The battery supplies a potential
of 10.0 V, has a negligible internal resistance, and is connected in
series with a resistor R = 16.02. The left cylinder is filled with pure
distilled water, which has infinite resistivity. The right cylinder is filled
with a saltwater solution. It is known that the resistivity of the saltwater
solution is determined by the relationship p= (so/s) .m, where s
is the salinity in parts per thousand (ppt) and so = 6.30 ppt.
