The open fixed container in Figure P18.5 is filled with a liquid and fitted with a piston at the bottom. Give the direction (if any) of the following:

(a) the force \(\vec{F}_{\text {w }}^{c}\) exerted by the liquid on the wall at location \(A\),(b) the pressure \(P\) in the liquid at \(\mathrm{A},(c)\) the force \(\vec{F}_{\text {w } \ell}^{\mathrm{c}}\) exerted by the wall on the liquid at location \(\mathrm{B},(d)\) the force \(\vec{F}_{f p}^{\mathrm{c}}\) exerted by the liquid on the piston if the piston is pushed, and \((e)\) the force \(F_{i p}^{c}\) exerted by the liquid on the piston if the piston is pulled. \((f)\) Which answers would change if the container were filled with a gas rather than a liquid?
