Suppose a comet orbits the Sun on a highly eccentric orbit with an average (semimajor axis) distance of 1 AU. How long does it take to complete each orbit, and how do we know? Select one: A. One year, which we know from Kepler's third law. B. It depends on the eccentricity of the orbit, as described by Kepler's second law. C. It depends on the eccentricity of the orbit, as described by Kepler's first law. D. Each orbit should take about 2 years, because the eccentricity is so large.

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.
