Neco Model Questions Vol1 2019 Physics Question 29
Practice objective / multiple choice question 29 from the 2019 Neco Model Questions Vol1 Physics examination.
A U‑tube is open to the atmosphere at both ends. The left leg contains a column of mercury 0.40 m high. The right leg contains a column of water 0.30 m high topped by mercury of unknown height. The density of mercury is \(1.36\times10^{4}\) kg m\(^{-3}\) and that of water is \(1.0\times10^{3}\) kg m\(^{-3}\). Take \(g = 9.8\) m s\(^{-2}\). Determine the difference in height between the mercury levels in the two legs (left minus right) in centimetres.
