Neco Model Questions Vol1 2020 Physics Question 39
Practice objective / multiple choice question 39 from the 2020 Neco Model Questions Vol1 Physics examination.
The density of a liquid varies with depth according to \(\rho(h)=\rho_{0}\bigl(1+\alpha h\bigr)\), where \(\rho_{0}=1000\,\text{kg\,m}^{-3}\), \(\alpha=5.0\times10^{-4}\,\text{m}^{-1}\) and \(h\) is the depth in metres. Calculate the increase in pressure when descending from the surface to a depth of \(5\,\text{m}\). Take \(g=9.8\,\text{m\,s}^{-2}\). Express your answer in pascals (Pa) to three significant figures.
