A wooden block of volume 5.24 3 1024 m3 floats in water, and a small steel object of mass m is placed on top of the block. When m 5 0.310 kg, the system is in equilibrium, and the top of the wooden block is at the level of the water.

(a) What is the density of the wood?

(b) What happens to the block when the steel object is replaced by a second steel object with a mass less than 0.310 kg? What happens to the block when the steel object is replaced by yet another steel object with a mass greater than 0.310 kg?
