A series RCL circuit is at resonance and contains a variable resistor that is set to 206Ω. The power dissipated in the circuit is 1.30 W. Assuming that the voltage remains constant, how much power is dissipated when the variable resistor is set to 532Ω? Note: The ac current and voltage are rms values and power is an average value unless indicated otherwise.

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.
