An object of average density rho floats at the surface of a fluid of density rhofluid. (a) How must the two densities be related? (b) Now suppose the object is not fully submerged. In terms of rho and rhofluid what fraction of the object is submerged and what fraction is above the fluid? Check that your answers give the correct limiting behavior as rho → rhofluid and as rho → 0. (c)In view of the answers to parts (a) and (b), how can steel ships float in water?

it is the second option.

hello, i am papaguy.

i have found an answer to your question but use it as information.

information: because weak acids/bases have low concentration of hydrogen ions, the addition of water has a large impact on the ph. 2. a difference in 1 unit is a 10x difference in concentration for example; a liquid with ph of 3 is 10x more acidic than a liquid with a ph of 4. therefore, a liquid with a ph of 3 is stronger.

best of luck!
