Properties Of Matter

Figure below shows a liquid being pushed out of the tube by a piston having area of cross section \(2.0 \mathrm{~cm}^{2}\). The area of cross section at the outlet is \(10 \mathrm{~mm}^{2}\). If the piston is pushed at a speed of \(4 \mathrm{~cm} \mathrm{~s}^{-1}\), the speed of outgoing fluid is __________ \(\mathrm{cm} \mathrm{s}^{-1}\)
