Let's say you have a plot for pendulum experiment. let's assume g for this experiment was measured (from the slope of the plot) to be 9.78 [ms^-2]. the vertical intercept, however, is 0.021 [s^2]. what might this translate to for a measurement of the length offset systematic in all the length measurements? length offset =[mm] .011

Arefrigerator uses r-134a as the working fluid and operates on the ideal vapor-compression refrigeration cycle except for the compression process. the refrigerant enters the evaporator at 120 kpa with a quality of 34 percent and leaves the compressor at 70°c. if the compressor consumes 450 w of power, determine (a) the mass flow rate of the refrigerant, (b) the condenser pressure, and (c) the cop of the refrigerator.
