The winch is used to drag 375 N crate up a ramp at a constant speed of 75 cm/s by means of a rope that pose parallel to the surface of the ramp the rope slips upward at 33° above the horizontal in the No efficient of kinetic friction between the ramp in the crate is .25 what is the tension of the rope

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.
