What is the minimum area of the top surface of a slab of ice with a uniform thickness of 0.30 m floating on fresh water that will hold up a car of mass 1100 kg sitting at the center on the top surface? The density of water is 1.0 × 103 kg/m3 and density of ice is 0.92 × 103 kg/m3 .

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.
