Imagine you want to create the illusion of a brick sitting on top of still water as if it were on hard ground. To accomplish this, you use a 5 Liter (1 Liter = .001 m3)cube of styrofoam (whose density you know is 0.15 kg/L) that you plan to put under the brick such that the styrofoam is fully submerged but the brick is not touching the water. Now to find a brick that will complete the illusion. Q1:What mass must the brick have in order to complete the illusion? Does it matter what the density or volume of the brick is? Q2:If you started to add small pieces of brick, what would happen? Speak qualitatively about the limit - when would the compound object (styrofoam plus bricks) stop floating and eventually sink to the bottom.
