. A small solid ball is released from rest while fully submerged in a liquid and then its kinetic energy is measured when it has moved 4.0
cm in the liquid. Figure 14-40 gives the results after many liquids are
used: The kinetic energy K is plotted versus the liquid density ρliq, and
Ks = 1.60 J sets the scale on the vertical axis. What are (a) the density
and (b) the volume of the ball?

An ice-making machine inside a refrigerator operates in a carnot cycle. it takes heat from liquid water at 0.0 degrees celsius and rejects heat to a room at a temperature of 19.2 degrees celsius. suppose that liquid water with a mass of 76.3kg at 0.0 degrees celsius is converted to ice at the same temperature. take the heat of fusion for water to be l_f = 3.34*10^5 j/kg.how much energy e must be supplied to the device? express your answer in joules.
