Answer
a) $P=1.45\times 10^5Pa$
b) $P=1.54\times 10^5Pa$
c) Because the water pressure increases with depth
Work Step by Step
(a) We know that
$P=P_{at}+\rho gh$
We plug in the known values to obtain:
$P=1.01\times 10^5+(1000)(9.81)(4.5)$
$P=1.45\times 10^5Pa$
(b) We know that
$P=P_{at}+\rho gh$
We plug in the known values to obtain:
$P=1.01\times 10^5+(1000)(9.81)(5.5)$
$P=1.54\times 10^5Pa$
(c) We know that the water pressure increases with depth, hence the bands near the bottom are more closely spaced to provide enough support.
