The electric dipole moment of a dipole in a 300 n/c electric field is initially perpendicular to the field, but it rotates so it is in the same direction as the field. if the electric dipole moment has magnitude 2.0 x 10- cm, what is the work done by the field? a) w12 x 10-7j b) w-6.0 x 10-7j c) w +6.0 x10-? j d) w +12 x 10-7 j =

Agas expands from an initial volume of 0.040 m^3 and an initial pressure of 210 kpa to a final volume of 0.065 m^3 while its temperature is kept constant. how much work is done by the system?

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.
