1) do the gain, slew rate, cutoff frequency, and unity gain frequency of an op amp change with the circuit it is used in? when these same parameters are examined for an op amp amplifier circuit from the input of the circuit to the output, do they change with the circuit used, i. e, do parameters like unity-gain frequency, cutoff frequency, etc. differ for inverting and non-inverting amplifiers? 2) why does an op amp show a gain/phase change with frequency?

An ideal vapor-compression refrigeration cycle is employed to maintain a building temperature of 23°c when the outside temperature is 37°c. the cycle operates at steady state using ammonia as the working fluid. the mass flow rate of the refrigerant is 15 kg/min. the refrigerant enters the compressor at 1.5 bar and 10 °c. the condenser pressure is 20 bar and the temperature at the condenser exit is 45 °c. determine (a) the compressor power in kw. (b) the refrigeration capacity in tons. (c) the coefficient of performance. d) the maximum theoretical coefficient of performance.
