(a) If the tension in the string in Example 15-12 is 0.89 N, what is the volume of the wood? Assume that everything else remains the same.

(b) If the string breaks and the wood floats on the surface, does the water level in the flask rise, drop, or stay the same? Explain.

(c) Assuming the flask is cylindrical with a cross-sectional area of 62 cm2, find the change in water level after the string breaks.
