Gce Model Questions Vol1 2021 Physics Question 39
Practice objective / multiple choice question 39 from the 2021 Gce Model Questions Vol1 Physics examination.
A sealed vertical tube of length \(1.00\ \text{m}\) contains air at \(20^{\circ}\text{C}\) and a pressure equal to atmospheric pressure (\(1.00\ \text{atm}\)). The tube is inverted and its open end is placed at a depth \(d\) below the surface of a lake (water density \(1000\ \text{kg m}^{-3}\)). Assuming the temperature of the trapped air remains at \(20^{\circ}\text{C}\), find the depth \(d\) (in metres, to two decimal places) at which the air column is compressed to half its original length.
