Neco Model Questions Vol1 2024 Physics Question 27
Practice objective / multiple choice question 27 from the 2024 Neco Model Questions Vol1 Physics examination.
In a lake the water density varies linearly with depth according to \(\rho(z)=\rho_{0}\bigl(1+\alpha z\bigr)\), where \(\rho_{0}=1000\,\text{kg·m}^{-3}\), \(\alpha=1.0\times10^{-4}\,\text{m}^{-1}\) and \(z\) is measured downward from the surface. Calculate the increase in pressure from the surface to a depth of 20 m. Take \(g=9.8\,\text{m·s}^{-2}\).
