A block of balsa wood placed in one scale pan of an equalarm balance is exactly balanced
Question:
A block of balsa wood placed in one scale pan of an equalarm balance is exactly balanced by a 0.115-kg brass mass in the other scale pan. Find the true mass of the balsa wood if its density is 150 kg/m3. Explain why it is accurate to ignore the buoyancy in air of the brass but not the buoyancy in air of the balsa wood?
