Ok, I think I may have got the correct answer, but I am not sure.
I set the density of the metal times the volume plus the density of wood times the volume equal to the density of water times volume.
Equation looks like this...
Homework Statement
one cm of a 10cm long rod is made of metal and the rest wood. Th metal has a density of 5,000kgm^3 and the wood has a density of 500kg/m^3. When the metal part points down ward, how much of the rod is underwater.
Homework Equations
water density = 1000kg/m^3...
