An object floats on water with 80% of its volume below the surface. the same object when placed in another liquid floats on that liquid with 72% of its volume below the surface. determine the density of the unknown fluid.

0.9g/cm cubed, this is my full answer however i have to write at least 20 characters so this is filler :)

1) when you rub your hands together quickly, the kinetic energy is converted to mechanical energy.2) thermal energy from the sun travels to earth as infrared waves.3) energy is transferred through the matter of space by electromagnetic waves. 4) when a match is burned, chemical potential energy is converted to thermal and radiant energy. 5) seismicwaves are caused by back and forth movement , or vibration, of an object. 6) mechanicalenergy in an engine changes thermal energy into kinetic energy to make a car move.
