When solid a of mass 12g is completely immersed in ameasuring cylinder filled with water it displace the same volume of water as dose solid b of mass 8g what can be deduced about the densities of solid aandb

Solid A has a greater density than solid B.

Since they displace the same volume of water, then A and B have the same volume. With density being mass/volume, if they have the same volume, then the one with the greater mass has greater density.

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.
