(Question 111) Answer step to step the following question: A bottle floating with the neck up in a bucket having water, as in the figure below. In the equilibrium position it is submerged with a depth of d0, starting from the surface water level. Show that, if it is pushed to a depth d then released, it will perform an simple harmonic movement and determine its frequency of oscillation. If d0 = 20 cm, what is the period of the oscillations? Justify your answer.
