A piece of wood with a density of 730 kg/m3 is tied with a string to the bottom of a water-filled flask. The wood is completely immersed, and the tension in the string is 1.12 N.
(a) What is the volume of the wood?
m^3
(b) Assuming the flask is cylindrical with a cross sectional area of 65 cm2, find the change in water level after the string breaks.
