A rectangular block of solid carbon (graphite) Iloats at
Chapter 3, Problem 3.7(choose chapter or problem)
A rectangular block of solid carbon (graphite) Iloats at the interface of two immiscible liquids. The bottom liquid is a relatively heavy lubricating oiL and the top liquid is water. Of the total block volume, 54.2% is immersed in the oil and the balance is in the water. In a separate experiment, an empty flask is weighed, 35.3 cmJ of the lubricating oil is poured into the flask, and the flask is reweighed. If the scale reading was 124.8 g in the first weighing, what would it be in the second weighing? (Suggestion: Recall Archimedes' principle, and do a force balance on the block.)
