A water hose 5 cm in diameter is used by a gardener to fill it 100.0-liter bucket. The gardener notices that it takes 10 min to fill the bucket. A nozzle with an opening of cross-sectional area 0.25 cm2 is then attached to the hose. The nozzle is held so that water is projected horizontally from a point 3.00 m above the ground.

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.
