You are pumping up a bicycle tire with a hand pump, the piston ofwhich has a 2.00 cm radius. (a) What force in newtons must you exert to create a pressure of \({\rm{6}}{\rm{.90 \times 1}}{{\rm{0}}^{\rm{5}}}{\rm{ Pa}}\) (b) What is unreasonable about this(a) result? (c) Which premises are unreasonable or inconsistent?
The outward force on one end of an air tank was calculated in Example 11.2. How is this force balanced? (The tank does not accelerate, so the force must be balanced.)?
What fluid is in the device shown in Figure\[{\rm{11}}{\rm{.29}}\]if the force is\[{\rm{3}}{\rm{.16 \times 1}}{{\rm{0}}^{{\rm{ - 3}}}}{\rm{ N}}\]and the length of the wire is\[{\rm{2}}{\rm{.50 cm}}\]? Calculate the surface tension 纬and find a likely match from Table\[{\rm{11}}{\rm{.3}}\].
